This may have been a function of the conda environment I was working in. I created a new conda environment and was able to successfully install polaris-lib.

Thanks for submitting this and following up, @PatWalters. I do believe it could be related to the version of pydantic you have installed in your rdkit_2023_05 conda environment. Would you mind sharing what that version was?

We should update the polaris environment spec to only accept pydantic versions which expose the ValidationInfo class.

Thanks! Conda should be throwing an error here about dependency conflicts based on the versioning we already specify for the polaris environment. We'll dig into this a bit further and keep this issue open until we have a more concrete explanation.

Thanks for the help!
