Changeset:   4d27dc97e6a5
Branch:      yt
User:        mzingale
Date:        2017-04-13 19:35:55+00:00
Summary:     use try/except for creating the config directory and writing
the file.  on supercomputers, we don't always have access to
the home directory from the compute nodes, so the import of
yt fails.  This patch makes yt work at OLCF
