Environment details

GPU: 4070 Super

When I launch ComfyUI it shows these versions:
Python version: 3.13.6
pytorch version: 2.8.0+cu129

Based on pytorch version I've done:
.\python_embeded\python.exe -m pip install -U "triton-windows<3.5"

.\python_embeded\python.exe -m pip show triton-windows
shows 3.4.0.post20

I am dumb, I forgot to check closed issues. Working on it.

[woct0rdho]

Did you copy the folders include and libs? See https://github.com/woct0rdho/triton-windows#8-special-notes-for-comfyui-with-embeded-python

[Rinkashikachi]

Yes, sorry, my bad. I skipped that part of the instruction because first half of it looked like a duplicate of "2. Python environment".

Thank you for quick and thorough responses. Might I suggest that you somehow reorganize this part of instructions so that people don't jump to stupid conclusions like I did?
