Hi! I'm having an issue converting a Phi3 model to a torch scripted model. Code, error, and versions below. Any guidance would be super helpful, thanks!
Here is the code:
Here is the error:
torch==2.5.1
transformers==4.51.3
Here is the code:
from transformers import AutoModelForCausalLM
import torch
base_model = "microsoft/Phi-3-mini-4k-instruct"
model = AutoModelForCausalLM.from_pretrained(
base_model,
return_dict=True,
low_cpu_mem_usage=True,
torch_dtype=torch.float16,
device_map="auto",
trust_remote_code=True,
torchscript=True
)
scripted_model = torch.jit.script(model)Here is the error:
