Bug summary

When running a python script containing matplotlib module on a remote server machine, got the following errors:

import matplotlib.pyplot as plt

File "path_to_env/lib/python2.7/site-packages/matplotlib/pyplot.py", line 29, in

Code for reproduction

python run.py

Actual outcome

as above.

I need to clarify this only crashes when running it on a remote machine. If i tried to run it locally, it worked just fine. The remote machine should be using the same env as my local because I used SGE command 'qsub -V' which would pass all my local environment variables to the remote machine. Also, I checked that I have enough space under /home/ and others on that remote machine.

Expected outcome

quietly load in or rebuild needed fonts.
