Sometimes it is useful to install python packages that are not part of psana-python or install particular versions of a software package.  These should be done from the "psbuild-rhel7" machines since they have internet access.  In particular "psana" nodes do NOT have internet access.

If you change psana versions at a later time, the package you installed previously with pip may not work anymore.  If so you can uninstall the old version with "pip uninstall rayopt" and install it again using the new version of psana.
