An error message is displayed while loading Python modules when Maestro starts. What do I do?
ImportError: No module named core ...
ImportError: numpy.core.multiarray failed to import
The error may arise if PYTHONPATH is set to a location other than the one in the Schrödinger software installation. One option is to unset the PYTHONPATH variable before starting Maestro. Another is to set the SCHRODINGER_PYTHONPATH variable to a string that contains a single space character. See Article 1842 for information on setting environment variables. For example, on Linux enter the following command in a terminal window:
csh/tcsh: setenv SCHRODINGER_PYTHONPATH " "
bash/ksh: export SCHRODINGER_PYTHONPATH=" "
If you are running an old release, issues like this can also arise when there is more than one Schrodinger suite installed in a single $SCHRODINGER directory. This practice is no longer permitted.
