Thank. I was able to get psi4 installed using “conda install psi4 python=3.12 -c conda-forge”.
However, when I also “conda install pytest” after the psi4 install, it rolled back the psi4 to 1.9-py312hef1bf4d_1, and then resulted in an psi4 error about “Following atoms are too close” - this error you answer previously about numpy 1 vs 2 (see https://forum.psicode.org/t/atoms-are-too-close-after-installation/3121 and https://github.com/psi4/psi4/issues/3184). However, if I do a “pip3 install pytest”, then everything works well with psi4 1.9.1-py312ha9da0b5_8.
Best regards,
Karl
