Frequent `# fatal: not a git repository (or any of the parent directories): .git` messages.

[JSKenyon]

I believe that these messages are triggered by this code:

RIMS/DynSpecMS/dynspecms_version.py

Line 10 in 631048f

result=subprocess.check_output('git describe --tags', shell=True,universal_newlines=True).rstrip()

I would suggest checking for the existence of .git before attempting to run the subprocess command. When installed in an image, it will not appear as a github repository (or if the user pip installs directly from github).

It's already in a try/except for that reason though: presumably the right thing to do here is to suppress the error message you get, which isn't in fact a fatal error for the code.

[JSKenyon]

The problem is that the message is coming from the subprocess, not the Python process itself (I think). So either the terminal output of the subprocess needs to be caught and discarded, or the check for a git repo needs to be done outside. This is purely a cosmetic fix.

[mhardcastle]

Agreed, I think it should be possible just to catch and discard standard error for the subprocess, or direct to /dev/null in the shell call.
