When you want to use matplotlib in deepo, we suggest using a non-interactive backend such as agg. In your figure-generating script, just call the matplotlib.use() directive before importing pylab or pyplot:

import matplotlib
matplotlib.use('agg')
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.savefig('myfig')
