Long time lurker first time poster.  Sorry if this is the wrong place or if this bug is due to user error.

I installed zeppelin 0.7.0 from binaries and attempted to use a python3-based venv, but I find that matplotlib appears to be broken.

%python
import matplotlib
import sys
print(sys.version)
print(sys.executable)
print(matplotlib.__version__)
import matplotlib.pyplot as plt
plt.plot([1,2,3])
