Skywork/SkyReels-V2-I2V-1.3B-540P

I am in a runpod environment. Ubuntu 22.04 with 1xL40 GPU. I set up a conda environment for skyreels and installed python 3.12. I downloaded skyreels and ran pip install -r requirements.txt . I tried to run the difference forcing example, and I get this error.

Traceback (most recent call last):
