ComfyUi on RunPod- Launching issue

[wermind00]

Hi! I am new in Comfy Ui. I run it through RunPod, first time everything worked, however after trying to insall missing nodes i had to refresh it and cannot run ComfyUi with second try. Please help! While trying to run it i come across this error: ImportError: /workspace/ComfyUI/venv/lib/python3.10/site-packages/torch/lib/libtorch_cuda.so: undefined symbol: ncclCommRegister
