I support a group of cryosparc users who have recently run into an issue using Topaz Train. Here is the output of the failed Topaz Train job.

I should mention that this user group had previously been running into issue with Topaz denoise jobs - that issue turned out to be related to PyTorch. The Topaz installation instructions on the Cryosparc site suggest using Python3.6 and installing via Conda - when following those steps PyTorch was using a version of Cuda that was too old for our A100 cards (these cards need Cuda 11+).
I created a new conda environment using Python3.8 (hoping to get a newer version of PyTorch). I then had to install everything via pip rather than conda install as I was only getting the CPU version of PyTorch when installing via conda, even when specifying cuda toolkit.
Here is the output of pip freeze

That solved the issues we were seeing with denoise jobs âfailing successfullyâ and resulted with the âdenoised_micrographsâ directory being empty. My concern is that using newer versions of Pytorch may have introduced an issue with Topaz Train jobs. I donât actually use the software much myself so Iâm unsure where to look next.
Any help or advice on how to get this environment working for Topaz jobs would be helpful. Thank you in advance to the community here.
