Dear all,
I’m attempted a DF-FNO-CCSD(T)/aug-cc-pvdz computation on sumanene. I’m getting an asinine energy. If I use cc-pvdz I get a normal energy that is about the same as another program’s CCSD energies. I installed stable release 1.2.1 and the python 3.5 version of it for linux. The hardware is intel haswell cpu’s.
