I tried to install pytorch with cuda enabled using the following command in conda prompt: conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia.  
but I got the following error: (‘Connection broken: IncompleteRead(217545068 bytes read, 176616422 more expected)’, IncompleteRead(217545068 bytes read, 176616422 more expected)).

I am not sure what this means to me. Could anyone please explain why this is happening?

It seems your internet connection might have issues so you might want to retry the download.

Works for me:

```python
conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia
