GTX 1050ti CUDA error: no kernel image is available for execution

1

Hello!

help me please, im already tired.

i try run SeedVR2 with portable Comfy and getting this error.

i already try several methods but they dont help.

and i want try this:

pip install torch==2.7.0 torchvision==0.22.0 torchaudio==2.7.0 --index-url https://download.pytorch.org/whl/cu126 --force-reinstall

but it gives me error “cannot find satisfying etc”. but version 2.9 or higher install easy. how fix this?

install mmcv-full can help?

Also i didnt have installed Visual studio but i dont think problem in it.

i have now:

Python 3.14

Cuda 12.6

CUDA error: no kernel image is available for execution on the device
Search for `cudaErrorNoKernelImageForDevice’ in CUDA Runtime API :: CUDA Toolkit Documentation for more information.
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

Your Python version is most likely to new for PyTorch 2.7.0 assuming you really want to install this older release. Downgrade Python in this case and try to reinstall PyTorch afterwards.

by one advice i downloader portable Comfy with cu128 with 2.9.0 pytorch and found some things need to fix.

even i use proper command and firsty remove 2.9.0 by pip uninstall torch -y

and after it shows that no any pytorch installed i got and install 2.8.0, at Cmd it download exactly 2.8.0 but at launch ComfyUI it says exactly that it runs with 2.9.0 and above that i need Install PyTorch with 12.6 cuda when it see i have GTX 1050ti.

i think seems PyTorch installs for Windows even i run Cmd under/in ComfyUI portable folder and shows exactly this path in Cmd.

What im doing wrong?

how correctly run Cmd to delete 2.9.0 and install 2.8.0 PyTorch at this Portable ComfyIu?

please, help me! thanks.

We have seen similar issues in the past reported by users depending on ComfyUI which seemingly ignores the already installed PyTorch binary. I’m not familiar with ComfyUI so also don’t know how to ask it to install the correct PyTorch binary or to just reuse the already installed one.
