Error with Pb scf calculation

Hello,

When I run a Pb atom calculation I get an error. However, when I run a Ne atom, it runs okay.

Input: For Pb
#Any line starting with the # character is a comment line #! Sample HF/LANL2DZ memory 2000 mb molecule Pb { Pb 0 0 0 } set basis LANL2DZ energy(‘scf’)

Error: for Pb

Input for Ne
#Any line starting with the # character is a comment line #! Sample HF/LANL2DZ memory 2000 mb molecule Ne { Ne 0 0 0 } set basis LANL2DZ energy(‘scf’)

What should I be doing different for Pb? Is it something do with the way psi4 was compiled?

Thanks for your time and support.

Please read and follow our best practices for posting topics. Your files are extremely difficult to read.

Yes, we will need to know how you installed Psi. You need libecpint to do this calculation, which you do not have on your installation, for some reason.

Sorry about that.

I used the following command to install psi4 on a windows machine (64 bit) via mini conda
conda install psi4 python=3.8 -c psi4

Unfortunately, it doesn’t look like there’s a libecpint package available for Windows, https://anaconda.org/search?q=libecpint . Can you get to a Linux machine?

iirc, there’s a missing dependency of libecpint on Windows, and I had a plan for how to build it out on conda-forge, but I haven’t gotten to it yet.
