PSI4 and openff-toolkits compatibility

[ph7klw76]

I started with a fresh environment under miniconda i installed openff-toolkits and then installed PSI4 or vice versa

The 2 modules seem not compatible, It keeps looping in resolving conflicts I tried in python 3.9 environments, python 3.7 and python 3.8 environments. It is the same.

installing both simultaneously with the following command worked for me, you can give this a try conda create -n env_name -c conda-forge -c psi4/label/dev psi4 openff-toolkit

Thanks for writing in, @ph7klw76.

Could you let us know a bit more about your computing environment? Are you on mac or linux? We've had some difficulties making envs with psi4 and usually use the trick that @pavankum posted.

Recent versions of Psi4 (1.8+, maybe earlier) are available on conda-forge and should work better together now. Please re-open or file a new issue if there are still issues!
