安装了CUDA Toolkit 12.5, env.yaml怎么修改?

Question

CUDA Toolkit 11.3不支持ubuntu 22, 我安装的是CUDA Toolkit 12.5,
我改了env里的cudatoolkit==12.5.1,
跑conda env create -f 0202-env.yaml　的结果:

跑 conda activate videocomposer的结果:

你可以用  nvidia-smi  和 nvcc -V  查看你环境的驱动版本和 CUDA Toolkit 版本，一般来说，只要Toolkit 版本是 11.8 兼容性都是很不错的。
