Importing filterbank breaks matplotlib throughout entire script about blimpy

Can you try with this new script? I made a local edit and hadn't pushed it to github

PS: You're probably also seeing

/usr/local/lib/python2.7/dist-packages/matplotlib/__init__.py:1350: UserWarning:  This call to matplotlib.use() has no effect
because the backend has already been chosen;
matplotlib.use() must be called *before* pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.

What is likely happening in your version is that matplotlib is necessarily loaded when you import filterbank. For example, this code should work:

import filterbank
import random

x = random.sample(range(1,100), 10)
y = random.sample(range(1,100), 10)
filterbank.plt.plot(x,y)
filterbank.plt.savefig('myplot.pdf', format='pdf')

You are correct, I am seeing the UserWarning above.

Anyways, I cloned the most recent version of filterbank.py and tried it; that seems to have fixed the problem and the plot is generated without issue, though the UserWarning persists. 😕

EDIT: Never mind. When I use the following code there is no warning and it runs as expected:

import filterbank
import random
import matplotlib.pyplot as plt

x = random.sample(range(1,100), 10)
y = random.sample(range(1,100), 10)
plt.plot(x,y)
plt.savefig('myplot.pdf', format='pdf')

Thank you!
