Update torch to 2.5.0

In my experience, many comfyui nodes have conflicts, if upgrading torch still does not solve the problem, please create a new comfyui directory (for mochi only), may solve the problem

Thank you for your reply. Sorry for the silly question, but how do I install torch 2.5?

Thank you for your reply. Sorry for the silly question, but how do I install torch 2.5?

Try any of the following command lines:

pip3 install torch==2.5.0 torchvision --index-url https://download.pytorch.org/whl/test/cu118 pip3 install torch==2.5.0 torchvision --index-url https://download.pytorch.org/whl/test/cu121 pip3 install torch==2.5.0 torchvision --index-url https://download.pytorch.org/whl/test/cu124

Thank you. I would use any of those commands on a cmd window in the mochi folder or the comfy one?

Yes, it seems mochi has no strict requirements for the cuda version. In my own case, I use cu118

Run In the ComfyUI_windows_portable\python_embeded folder: python.exe -m pip install -U torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu124

Still getting the same window...frustrating.

It feels like there are many possibilities, maybe there is a problem with the version of python you installed? Try to install a version that is compatible with your system. Use the following two lines to see the version? python --version python -c "import platform; print(platform.architecture())"

Or if phthon hasn't been upgraded to a new version, try: python -m pip install --upgrade pip

Thank you for your reply. I ended up having problems even starting comfy with the same message so I reinstalled comfy and nodes and it’s working now. Thanks again 👍
