11.3 binaries compatibel with Cuda 11.7?

1

Hello all. I have Cuda 11.7, with the 515 driver, on my system. I wanted to see if I could get a functional version of pytorch quick-and-dirty (no downgrading or building from source), so I used this command, not really expecting it to work:

conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch

Surprisingly, these binaries seem to work, at least for some basic things I’ve tested so far. Will this work in general? Or did conda install a local 11.3 cuda toolkit? Either way - should I be very worried about unstable behavior? Or is it probably fine?

The binaries ship and will use their own CUDA runtime and your local CUDA toolkit will be used if you are building PyTorch from source or e.g. a CUDA extension.
To run the binaries you would only need to install the NVIDIA driver.
