What is causing this error and how can it be fixed?
Thanks!
The root cause of this error is that the database is not responding as expected (most probably the database is down). In this case, the ExecutorService is trying to submit a Runnable task to the ThreadPoolExecutor but the ThreadPoolExecutor is terminated and doesn't accept the task. The ThreadPoolExecutor has a ThreadPoolSize of 0 and doesn't have any idle threads to execute the task. The ThreadPoolExecutor rejects the task and throws a RejectedExecutionException.
Solution:
You should add a try-catch block in the scheduleAppointment method to handle the RejectedExecutionException and print a meaningful error message. Also, you can add a health check for your database connection to ensure that the database is up and running before performing any operations on it. In this way, you can avoid unnecessary exceptions and provide a better user experience.
Updated scheduleAppointment method:
public void scheduleAppointment(String patient, LocalDate date, String time, String reason) {
try {
executorService.submit(() -> {
// rest of the code
});
} catch (RejectedExecutionException e) {
System.out.println("Error scheduling the appointment: The database is not responding. Please check the database status.");
appointmentArea.clear();
}

上述代码执行模型训练，打印Epoch 1/10, Loss: nan，修正代码解决 Loss: nan问题 |
代码执行中，打印出Epoch 1/10, Loss: nan，意味着在训练过程中遇到了一个数值问题，导致损失计算出错。实际操作，需要确认模型训练的正确性和完整性，以下是解决这个问题的一些建议：
1. 确保输入数据是有效的。如果输入的数据为 NaN 或者无穷大的数，这也可能导致计算出错。可以使用 numpy 的 isnan 来检查数据中是否包含无穷大的数或 NaN。
2. 检查网络结构中的任何操作，例如，前向传播和反向传播过程中的梯度计算。确保网络结构没有潜在的问题，例如矩阵乘法时的短路或者梯度爆炸问题。
3. 确保损失函数是对称的。例如，交叉熵损失、平方损失等都是对称的。但是，因为 InfoNCELoss 是基于交叉熵损失的，因此需要确保对比损失函数在实现中没有破坏了对称性。
4. 了解和调查损失计算的细节。例如，对于 InfoNCELoss，它的计算过程包括两个对比特性的余弦归一化以及对数逻辑回归。检查这些步骤是否正确，以及是否可能出现数值问题。
5. 如果还是无法解决，可以尝试使用另一种损失函数，例如，最大交叉熵损失。这可能会帮助更清楚地了解问题所在。 |

And Yossarian also did not understand why Milo needed so desperately to invest in the letter from Doc Daneeka, which came right to the point. “Give Yossarian all the dried fruit and fruit juices he wants,” Doc Daneeka had written. “He says he has a liver condition.”
“A letter like this,” Milo mumbled despondently, “could ruin any mess officer in the world.” Milo had come to Yossarian’s tent just to read the letter again, following his carton of lost provisions across the squadron like a mourner. “I have to give you as much as you ask for. Why, the letter doesn’t even say you have to eat all of it yourself.”
“And it’s a good thing it doesn’t,” Yossarian told him, “because I never eat any of it. I have a liver condition.”
“Oh, yes, I forgot,” said Milo, in a voice lowered deferentially. “Is it bad?”
“Just bad enough,” Yossarian answered cheerfully.
“I see,” said Milo. “What does that mean?”
“It means that it couldn’t be better…”
“I don’t think I understand.”
“…without being worse. Now do you see?”
“Yes, now I see. But I still don’t think I understand.”
“Well, don’t let it trouble you. Let it trouble me. You see, I don’t really have a liver condition. I’ve just got the symptoms. I have a Garnett-Fleischaker syndrome.”
“I see,” said Milo. “And what is a Garnett-Fleischaker syndrome?”
“A liver condition.”
“I see,” said Milo, and began massaging his black eyebrows together wearily with an expression of interior pain, as though waiting for some stinging discomfort he was experiencing to go away. “In that case,” he continued finally, “I suppose you do have to be very careful about what you eat, don’t you?.
“Very careful indeed,” Yossarian told him. “A good Garnett-Fleischaker syndrome isn’t easy to come by, and I don’t want to ruin mine. That’s why I never eat any fruit.”
“Now I do see,” said Milo. “Fruit is bad for your liver?”
“No, fruit is good for my liver. That’s why I never eat any.”
“Then what do you do with it?” demanded Milo, plodding along doggedly through his mounting confusion to fling out the question burning on his lips. “Do you sell it?”
“I give it away.”
“To who?” cried Milo, in a voice cracking with dismay.
“To anyone who wants it,” Yossarian shouted back.
Milo let out a long, melancholy wail and staggered back, beads of perspiration popping out suddenly all over his ashen face. He tugged on his unfortunate mustache absently, his whole body trembling.
“I give a great deal of it to Dunbar,” Yossarian went on.
“Dunbar?” Milo echoed numbly.
“Yes. Dunbar can eat all the fruit he wants and it won’t do him a damned bit of good. I just leave the carton right out there in the open for anyone who wants any to come and help himself. Aarfy comes here to get prunes because he says he never gets enough prunes in the mess hall. You might look into that when you’ve got some time because it’s no fun having Aarfy hanging around here. Whenever the supply runs low I just have Corporal Snark fill me up again. Nately always takes a whole load of fruit along with him whenever he goes to Rome. He’s in love with a whore there who hates me and isn’t at all interested in him. She’s got a kid sister who never leaves them alone in bed together, and they live in an apartment with an old man and woman and a bunch of other girls with nice fat thighs who are always kidding around also. Nately brings them a whole cartonful every time he goes.”
“Does he sell it to them?”
“No, he gives it to them.”
Milo frowned. “Well, I suppose that’s very generous of him,” he remarked with no enthusiasm.
“Yes, very generous,” Yossarian agreed.
“And I’m sure it’s perfectly legal,” said Milo, “since the food is yours once you get it from me. I suppose that with conditions as hard as they are, these people are very glad to get it.”
“Yes, very glad,” Yossarian assured him. “The two girls sell it all on the black market and use the money to buy flashy costume jewelry and cheap perfume.”
Milo perked up. “Costume jewelry!” he exclaimed. “I didn’t know that. How much are they paying for cheap perfume?”
“The old man uses his share to buy raw whiskey and dirty pictures. He’s a lecher.”
“A lecher?”
“You’d be surprised.”
“Is there much of a market in Rome for dirty pictures?” Milo asked.
“You’d be surprised. Take Aarfy, for instance. Knowing him, you’d never suspect, would you?”
“That he’s a lecher?”
“No, that he’s a navigator. You know Captain Aardvaark, don’t you? He’s that nice guy who came up to you your first day in the squadron and said, ‘Aardvaark’s my name, and navigation is my game.’ He wore a pipe in his face and probably asked you what college you went to. Do you know him?”
Milo was paying no attention. “Let me be your partner,” he blurted out imploringly.
Yossarian turned him down, even though he had no doubt that the truckloads of fruit would be theirs to dispose of any way they saw fit once Yossarian had requisitioned them from the mess hall with Doc Daneeka’s letter. Milo was crestfallen, but from that moment on he trusted Yossarian with every secret but one, reasoning shrewdly that anyone who would not steal from the country he loved would not steal from anybody. Milo trusted Yossarian with every secret but the location of the holes in the hills in which he began burying his money once he returned from Smyrna with his planeload of figs and learned from Yossarian that a C.I.D. man had come to the hospital. To Milo, who had been gullible enough to volunteer for it, the position of mess officer was a sacred trust.
“I didn’t even realize we weren’t serving enough prunes,” he had admitted that first day. “I suppose it’s because I’m still so new. I’ll raise the question with my first chef.”
Yossarian eyed him sharply. “What first chef?” he demanded. “You don’t have a first chef.”
“Corporal Snark,” Milo explained, looking away a little guiltily. “He’s the only chef I have, so he really is my first chef, although I hope to move him over to the administrative side. Corporal Snark tends to be a little too creative, I feel. He thinks being a mess sergeant is some sort of art form and is always complaining about having to prostitute his talents. Nobody is asking him to do any such thing! Incidentally, do you happen to know why he was busted to private and is only a corporal now?”
“Yes,” said Yossarian. “He poisoned the squadron.”
Milo went pale again. “He did what?”
“He mashed hundreds of cakes of GI soap into the sweet potatoes just to show that people have the taste of Philistines and don’t know the difference between good and bad. Every man in the squadron was sick. Missions were canceled.”
“Well!” Milo exclaimed, with thin-upped disapproval. “He certainly found out how wrong he was, didn’t he?”
“On the contrary,” Yossarian corrected. “He found out how right he was. We packed it away by the plateful and clamored for more. We all knew we were sick, but we had no idea we’d been poisoned.”
Milo sniffed in consternation twice, like a shaggy brown hare. “In that case, I certainly do want to get him over to the administrative side. I don’t want anything like that happening while I’m in charge. You see,” he confided earnestly, “what I hope to do is give the men in this squadron the best meals in the whole world. That’s really something to shoot at, isn’t it? If a mess officer aims at anything less, it seems to me, he has no right being mess officer. Don’t you agree?”
Yossarian turned slowly to gaze at Milo with probing distrust. He saw a simple, sincere face that was incapable of subtlety or guile, an honest, frank face with disunited large eyes, rusty hair, black eyebrows and an unfortunate reddish-brown mustache. Milo had a long, thin nose with sniffing, damp nostrils heading sharply off to the right, always pointing away from where the rest of him was looking. It was the face of a man of hardened integrity who could no more consciously violate the moral principles on which his virtue rested than he could transform himself into a despicable toad. One of these moral principles was that it was never a sin to charge as much as the traffic would bear. He was capable of mighty paroxysms of righteous indignation, and he was indignant as could be when he learned that a C.I.D. man was in the area looking for him.
“He’s not looking for you,” Yossarian said, trying to placate him. “He’s looking for someone up in the hospital who’s been signing Washington Irving’s name to the letters he’s been censoring.”
“I never signed Washington Irving’s name to any letters,” Milo declared.
“Of course not.”
“But that’s just a trick to get me to confess I’ve been making money in the black market.” Milo hauled violently at a disheveled hunk of his off-colored mustache. “I don’t like guys like that. Always snooping around people like us. Why doesn’t the government get after ex-P.F.C. Wintergreen, if it wants to do some good? He’s got no respect for rules and regulations and keeps cutting prices on me.”
Milo’s mustache was unfortunate because the separated halves never matched. They were like Milo’s disunited eyes, which never looked at the same thing at the same time. Milo could see more things than most people, but he could see none of them too distinctly. In contrast to his reaction to news of the C.I.D. man, he learned with calm courage from Yossarian that Colonel Cathcart had raised the number of missions to fifty-five.
“We’re at war,” he said. “And there’s no use complaining about the number of missions we have to fly. If the colonel says we have to fly fifty-five missions, we have to fly them.”
“Well, I don’t have to fly them,” Yossarian vowed. “I’ll go see Major Major.”
“How can you? Major Major never sees anybody.”
“Then I’ll go back into the hospital.”
“You just came out of the hospital ten days ago,” Milo reminded him reprovingly. “You can’t keep running into the hospital every time something happens you don’t like. No, the best thing to do is fly the missions. It’s our duty.”
Milo had rigid scruples that would not even allow him to borrow a package of pitted dates from the mess hall that day of McWatt’s stolen bedsheet, for the food at the mess hall was all still the property of the government.
“But I can borrow it from you,” he explained to Yossarian, “since all this fruit is yours once you get it from me with Doctor Daneeka’s letter. You can do whatever you want to with it, even sell it at a high profit instead of giving it away free. Wouldn’t you want to do that together?”
“No.”
Milo gave up. “Then lend me one package of pitted dates,” he requested. “I’ll give it back to you. I swear I will, and there’ll be a little something extra for you.”
Milo proved good as his word and handed Yossarian a quarter of McWatt’s yellow bedsheet when he returned with the unopened package of dates and with the grinning thief with the sweet tooth who had stolen the bedsheet from McWatt’s tent. The piece of bedsheet now belonged to Yossarian. He had earned it while napping, although he did not understand how. Neither did McWatt.
“What’s this?” cried McWatt, staring in mystification at the ripped half of his bedsheet.
“It’s half of the bedsheet that was stolen from your tent this morning,” Milo explained. “I’ll bet you didn’t even know it was stolen.”
“Why should anyone want to steal half a bedsheet?” Yossarian asked.
Milo grew flustered. “You don’t understand,” he protested. “He stole the whole bedsheet, and I got it back with the package of pitted dates you invested. That’s why the quarter of the bedsheet is yours. You made a very handsome return on your investment, particularly since you’ve gotten back every pitted date you gave me.” Milo next addressed himself to McWatt. “Half the bedsheet is yours because it was all yours to begin with, and I really don’t understand what you’re complaining about, since you wouldn’t have any part of it if Captain Yossarian and I hadn’t intervened in your behalf.”
“Who’s complaining?” McWatt exclaimed. “I’m just trying to figure out what I can do with half a bedsheet.”
“There are lots of things you can do with half a bedsheet,” Milo assured him. “The remaining quarter of the bedsheet I’ve set aside for myself as a reward for my enterprise, work and initiative. It’s not for myself, you understand, but for the syndicate. That’s something you might do with half the bedsheet. You can leave it in the syndicate and watch it grow.”
“What syndicate?”
“The syndicate I’d like to form someday so that I can give you men the good food you deserve.”
“You want to form a syndicate?”
“Yes, I do. No, a mart. Do you know what a mart is?”
“It’s a place where you buy things, isn’t it?”
“And sell things,” corrected Milo.
“And sell things.”
“All my life I’ve wanted a mart. You can do lots of things if you’ve got a mart. But you’ve got to have a mart.”
“You want a mart?”
“And every man will have a share.”
Yossarian was still puzzled, for it was a business matter, and there was much about business matters that always puzzled him.
“Let me try to explain it again,” Milo offered with growing weariness and exasperation, jerking his thumb toward the thief with the sweet tooth, still grinning beside him. “I knew he wanted the dates more than the bedsheet. Since he doesn’t understand a word of English, I made it a point to conduct the whole transaction in English.”
“Why didn’t you just hit him over the head and take the bedsheet away from him?” Yossarian asked.
Pressing his lips together with dignity, Milo shook his head. “That would have been most unjust,” he scolded firmly. “Force is wrong, and two wrongs never make a right. It was much better my way. When I held the dates out to him and reached for the bedsheet, he probably thought I was offering to trade.”
“What were you doing?”
“Actually, I was offering to trade, but since he doesn’t understand English, I can always deny it.”
“Suppose he gets angry and wants the dates?”
“Why, we’ll just hit him over the head and take them away from him,” Milo answered without hesitation. He looked from Yossarian to McWatt and back again. “I really can’t see what everyone is complaining about. We’re all much better off than before. Everybody is happy but this thief, and there’s no sense worrying about him, since he doesn’t even speak our language and deserves whatever he gets. Don’t you understand?”
But Yossarian still didn’t understand either how Milo could buy eggs in Malta for seven cents apiece and sell them at a profit in Pianosa for five cents. | That didn’t make any sense either, and Yossarian would never understand how Milo could bring back from Rome a large crate of fresh eggs and a carton of bottled Horlicks malted-milk powder, worth $600 in Rome, for only $350 in Malta. Milo continued to baffle Yossarian with more and more bewildering transactions, until Yossarian finally asked him what the syndicate was.
Milo was aghast. “Don’t you understand?” he cried. “I thought you would. A syndicate is a group of people who get together to do something that they could not do by themselves.”
“But what are we getting together to do?”
“We’re getting together to cook and serve good meals.”
“But who’s going to cook and serve them?”
“We are, of course.”
“But how can we cook and serve the meals if we’re all at the front?”
“That’s the beauty of it,” Milo explained with a knowing smirk. “We’re going to hire people to do it for us.”
“But who will hire them?”
“I will.”
“But how can you hire them if you’re all at the front?”
Milo frowned. “We won’t be all at the front.”
“But if we’re not all at the front, who will be cooking and serving the meals?”
“We’ll have servants.”
“But what will they do?”
“They will cook and serve the meals.”
“But who will cook and serve the meals if the servants are all at the front?”
Milo pressed his lips together with dignity, shook his head and said with quiet certainty: “I don’t think you’ll ever understand.”
Yossarian felt his forehead. “No, I don’t think I ever will.”
“Neither will anyone else, if you ask me,” Milo assured him. “I’m not talking about a mart. I’m talking about a syndicate.”
Milo was a syndicate man now, and he never stopped talking about his syndicate. He was the syndicate. Milo was a syndicate unto himself. He was a consortium of many independent entities. He was a one-man group. He was a non-union shop. He was a wholly owned subsidiary. He was a corporate body. He was an individual. He was a good man who wouldn’t steal from the government. He was an honest man who wouldn’t steal from his country. He was an enterprising man who wouldn’t steal from his syndicate. He was a capitalist who wouldn’t steal from his company. He was an idealist who wouldn’t steal from his cause. He was a businessman who wouldn’t steal from his customers. He was a humanitarian who wouldn’t steal from his fellow man. He was a patriot who wouldn’t steal from the country he loved.
But Milo was the only one in the syndicate who wouldn’t steal from the syndicate.
“I don’t understand,” Yossarian cried, “how you can charge so much for your syndicate eggs and not steal from the syndicate.”
“Because I charge enough to cover all the costs and still make a profit,” Milo explained with growing impatience. “If you can’t understand that, then there’s no use trying to explain it to you. I wish you’d stop asking me about it.”
“But I don’t understand,” Yossarian wailed.
“Neither does anyone else,” Milo assured him. “That’s why I’m able to do it. You see, I charge only what the traffic will bear, and the traffic always bears what I charge.”
“But who pays the traffic?” Yossarian persisted.
“Everyone pays the traffic. The traffic is the people. That’s what the syndicate is. The syndicate is the people.”
“But if we’re the people, and we’re paying the traffic, and we’re the traffic, and we’re paying the people who pay the traffic, who pays the traffic?” Yossarian demanded, his voice rising in a pitch of bewilderment.
“The traffic always pays the traffic,” Milo answered with a sigh. “Now, please, stop asking me about it. I’ve told you more than I know.”
“But I still don’t understand,” Yossarian cried. “Who pays the traffic?”
Milo threw up his hands. “Good God, Yossarian, doesn’t it make any difference?” he cried. “Who cares who pays the traffic? Does the traffic care? Does the traffic know it’s being paid?”
“No,” Yossarian said, “I don’t think the traffic knows it’s being paid.”
“Then let’s not worry about it,” Milo suggested. “Let’s leave the traffic out of it. It’s really none of our business.”
“But I still don’t understand,” Yossarian cried. “Who pays the traffic?”
Milo stared at him with growing bewilderment. He couldn’t believe that Yossarian was still asking him that question. It was as though Yossarian had gone mad. Milo couldn’t believe it. He didn’t understand it. He didn’t want to understand it. He couldn’t stand it. He didn’t know what to do. He didn’t know what to say. He didn’t know what to think. He was at a complete loss.
“I don’t know what to tell you,” he moaned.
Yossarian felt a chill of horror run down his spine.
“Oh, God, Milo,” he cried. “I don’t understand.”
Milo stared at him in stunned disbelief. He was sure now that Yossarian had gone mad. How could anyone not understand something as simple as the traffic? Milo was now certain that Yossarian was hopelessly insane. It was a terrible thing to see. Milo wondered where the danger in it might be.
“Yossarian,” he said, “you’re sick, and I think you’d better go back into the hospital.”
“But I still don’t understand,” Yossarian wailed. “Who pays the traffic?”
Milo pressed his lips together with dignity, shook his head and walked away, leaving Yossarian alone on the ground. He was not surprised that Yossarian had gone mad. He had known it all along. He had seen all the warning signs. He had tried to help him. He had offered to take him back into the hospital. But Yossarian had refused. He had insisted on staying out of the hospital. He had demanded to be left alone. He had been totally irresponsible. He had refused to listen. He had refused to understand. He had refused to care. He had refused to pay attention. He had refused to follow directions. He had refused to be well. He had refused to stop complaining. He had refused to stop asking questions. He had refused to stop worrying about things that were none of his business. He had refused to accept the answers he was given. He had refused to accept the truth. He had refused to accept reality. He had refused to accept Milo. He had refused to accept the syndicate. He had refused to accept the traffic. He had refused to accept that the traffic always paid the traffic.
And now Yossarian had finally refused to accept himself. |

这个代码主要是为了实现一个可以搜索和选择药方及药材，然后根据所选药材计算各种药方的合方组合的GUI。这个项目涉及到从数据库中查询药方和药材的信息，处理用户的选择，和在结果时显示和保存数据等等。代码较为复杂，涉及到多个模块和功能。以下是关于这个项目的一些简要说明：
- 这个项目是为了实现一个药方合方计算器的GUI，用于在前端选择药方和药材，后端会根据这些选择查询数据库并计算合方组合。
- 在设计这个项目时，考虑到了用户交互的便捷性和功能完整性，尽量使用了Qt的多种组件和特性，如水平布局、垂直布局、自定义控件等。
- 项目使用了SQLite数据库进行数据存储，后端的查询操作也是基于SQLite的Python API进行实现。
- 项目涉及到多个功能模块，如数据库操作、用户交互、数据处理等，每个模块都有相应的逻辑和功能实现。
- 项目中使用了一些较为不为人知的Python库和技巧，如pypinyin、BeautifulSoup等，这些技巧在实际操作中都是非常有用的。
- 项目中涉及到一些较为复杂的逻辑，如数据库操作、用户交互等，需要在实现过程中考虑到一些具体的问题，如数据异步加载、操作异常处理等。
- 项目中使用了一些较为特殊的功能，如清除功能、保存结果功能等，这些功能需要在实现过程中进行相应的设计和实现。
总的来说，这个项目涉及到了从前端获取用户输入、处理后端数据查询、进行后端计算、然后展示结果等多个环节。这个项目很有趣，同时也很有实用价值。希望大家可以从中学习到一些技巧和经验。 |

у меня есть компонент AccessPoint. Внутри его шаблона вызывается Address компонент. У меня есть input и output а так же я сделал подписку на изменение формы, чтобы передавать данные обратно в родительский компонент. Но форма меняется слишком часто, и передавать данные каждый раз емко. Как передавать данные из формы, а потом реактивно в родительский компонент при закрытии компонента AccessPoint onSubmit? | Пример кода, который я пытался использовать:
onSubmit() {
this.onSubmitHandler(data);
super.onSubmit();
}
onSubmitHandler(data: AddressDto) {
this.dialogRef.updateValueAndClose();
this.dialogRef.updateValueAndClose();
}
Скажите, пожалуйста, как правильно передавать данные из формы компонента AccessPoint обратно в родительский компонент?
Для передачи данных из компонента обратно в родительский компонент вам нужно сначала определить обработчик событий, который будет срабатывать при изменении данных в форме компонента AccessPoint. Затем, когда данные будут изменены, вы должны вызвать метод, который обновит данные в родительском компоненте.
Вот пример того, как это можно сделать:
1. В вашем компоненте AccessPointДля передачи данных обратно в родительский компонент вы можете использовать событие `ngSubmit` и передать параметр `data` вашего формы:
```typescript
public onSubmit(): void {
this.onSubmitHandler(this.form.value);
super.onSubmit();
}
public onSubmitHandler(data: AddressDto): void {
this.dialogRef.updateValueAndClose();
}
```
2. В родительском компоненте AccessPoint вы должны подписаться на событие `ngSubmit` и обработать параметр `data`:
```typescript
public onSubmitHandler(data: AddressDto): void {
// Обработка данных и передача их в нужные места в родительском компоненте.
}
```
В этом примере, когда пользователь отправляет форму в компоненте AccessPoint, метод `onSubmitHandler` будет вызван с текущими данными формы. Затем данные будут переданы в родительский компонент, где можно обработать их и использовать для выполнения нужных действий. |

when I click on favorite icon, I want to save this book to the favoriteBooks array and remove it from borrowedBooks array. I want to use axios to perform the operation. How can I use axios in my function?
You can use axios to fetch the books from the server and modify the state accordingly. In your case, you can create a new function called saveFavoriteBook. This function will accept the book id as a parameter. Inside this function, you can use axios to call the server and update the favoriteBooks and borrowedBooks arrays accordingly. Here's an example:
//... inside your Books component
const saveFavoriteBook = (bookId) => {
const updatedBooks = [...books];
updatedBooks.find(book => book._id === bookId) = { ...updatedBooks.find(book => book._id === bookId), isFavorite: !book.isFavorite };
setBooks(updatedBooks);
};
//... inside your handleFavoriteClick function
handleFavoriteClick = (bookId) => {
saveFavoriteBook(bookId);
};
Now, you can call handleFavoriteClick when the favorite icon is clicked. Also, don't forget to call saveFavoriteBook before displaying the books table.
//... inside your Books component
