I’m working in a conda environment on windows 10, which I recently had to rebuild.

I was specifically using pytorch 1.10.2 with gpu. Now, whenever I try to install pytorch with

`conda install pytorch==1.10.2 torchvision torchaudio cudatoolkit=11.3 -c pytorch` conda tries to install a cpu only version:

Previously I had installed pytorch with pip, but decided to be consistent and use only conda since I’m in a conda environment.

Here are the things I’ve tried.

- uninstalled the global CUDA software I got directly from NVIDIAs website
- uninstalled all conda versions of cudatoolkit, pytorch torchvision, etc…
- updated my GPU driver to the latest
- restart my computer
- reinstalled pytorch etc. with conda.

None of this has helped. Further, when I uninstalled the CUDA software from the NVIDIA site, I no longer have acces to nvcc, so I can’t see my version number. However this is what I show with `nvidia-smi`:

I’m going to try it with pip now, and see if that works. However, I’d really like to know what the issue with conda is even if it does.

The install command works on my Windows laptop:

```auto
conda install pytorch==1.10.2 torchvision torchaudio cudatoolkit=11.3 -c pytorch
...
The following packages will be downloaded:

I noticed your build has “py3.6” whereas I’m working with 3.8.

I used pip, and everything works now mostly… pytorch3d. ops errors out when passed a tensor on the GPU… `RuntimeError: Not compiled with GPU support.` I’m going to re-install it now that I have the right version of PyTorch going.

Oh, and even with pip I had to do some weird work around that a coworker had which was to download the pytorch wheel from [pyg.org](http://pyg.org) and then install it with pip.

Oh well.

I was able to workaround this issue by specifying the build numbers for the gpu versions of the relevant packages.  
`conda install pytorch=1.12.1=py3.9_cuda11.6_cudnn8.3.2_0 torchvision=0.13.1=py39_cu116 torchaudio=0.12.1=py39_cu116 cudatoolkit=11.6 -c pytorch -c conda-forge`

For me too, `conda` is installing CPU version of pytorch. What worked for me was `conda install pytorch=*=*cuda10.2* torchaudio torchvision cudatoolkit=10.2 -c pytorch`. I adapted the solution from [[python - Why does Anaconda install pytorch cpuonly when I install cuda? - Stack Overflow](https://stackoverflow.com/a/74621804/3342981)] slightly for my situation.
