Do you have MSVC installed? |
Fixed in 863adf0 But this is only a clearer warning that MSVC is not found. You need to install MSVC and Windows SDK |
Hello @woct0rdho @GraftingRayman , so yes, I need to install the MSVC (added it to the path manually) but then I got a new error that WARNING: Failed to find CUDA. so I manually installed the latest version of CUDA now the errors are gone and comfy open without any error but then I try to run my usual workflow that is working without triton(Wavespeed) but when I try to run I got this error:
the some here has the same issue but slightly different I would say as the solutions suggested to him and worked for him in the comment are not relevant in my base, I am attaching the log so you guys can check the issue, hope there is a workflow for me:

This is fixed in 094edac I'll make a new release |
I've made the new release |
so I did that manually and as the OP said in 094edac I had installed cuda 12.4 instead of 12.8 but now I got a new error:
and here is the full log:

You need this: pytorch/pytorch#138211 This will be solved only when PyTorch 2.6 is out |
I made the following changes:
in the codecache.py and now I got a new error(crying in the corner), please suggest me how can I revert back so I can able to use something that is stable and workable for comfyUI portable btw here is the error:

Hmmm, your GPU is RTX 2060, it's too old (sm75) and Triton does not support compiling bf16 on it If you really want to try out triton, you can change bf16 to fp16 in the nodes or the code If you want to revert, just uninstall triton: Anyway, thanks for the bug report |
Hey, may you please tell me where can I change the bf16 to fp16 in the nodes? and is there any triton, comfyUI combination that will let me use Triton? any other old version? I watch to run wavespeed and in the backend it is using Triton, so if you may show some light? EDIT: |
Some ComfyUI nodes may convert the model dtype. As long as there is one bf16 in the middle of the computation, Triton may fail to compile it The easiest way for changing bf16 to fp16 is to look if there is somewhere to choose the dtype in all the nodes you use. If not, then you need some programming |
seems like the RTX 20 series is out of options for Triton and Wavespeed btw thanks for the support. |
I am installing it for the ComfyUI portable and got this error:
