What happened?

I have a fully working install on a device. However now I am trying to install it on a different device, and am stuck on this error. I copied all the versions from the working one to the new one, but no luck. I don't know where to look for issues at anymore.

Here are the only libraries that didn't get the exact versions, could it be one of these: datasets 2.17.0 depends on pandas evaluate 0.4.1 depends on pandas fastparquet 2024.2.0 depends on pandas>=1.5.0 mace-torch 0.3.4 depends on pandas pymatgen 2024.2.8 depends on pandas seaborn 0.13.2 depends on pandas>=1.2 transform 1.2.0 depends on pandas<1.5.0 and >=0.24.2

I have not done anything to the model, I just download it from github via the loadmodel method and it doesnt work. Clearing the cache did the same thing.

Any help is greatly appreciated.

Hi @dShado94, it seems that you are calling the latest version of MatGL (version:1.1.3) pretrained models from the Github repo. Please try to reinstall the latest version of MatGL instead of 0.9.2.

That worked! Thank you!
