Create a python package

CHTC has instructions for making a tarball of python packages (e.g. numpy, pyuvdata, etc).  This tarball is then either transferred to the execution host if it is under 100MB or downloaded from their web proxy server (with prior authorization) if 100MB or over.  This, coupled with a python installation via tarball, may be enough for execution hosts to run HERA calibration jobs.

Here is a sample set of instructions to build a python-packages tarball

cat > build.sub <<EOM

# Python build file

universe = vanilla

log = interactive.log

# Choose a version of Python from the table above
