Description
I use the following code snippet, similar to issue #3986 on Py35/matplotlib2.0.0 installed via Anaconda3:
import matplotlib.pyplot as plt
import numpy as np
import pickle
ax = plt.subplot(111)
x = np.linspace(0, 10)
y = np.exp(x)
plt.plot(x, y)
with open('bla.pickle', 'wb') as pickle_file:
pickle.dump(ax, pickle_file)
import matplotlib.pyplot as plt
import pickle
with open('bla.pickle', 'rb') as pickle_file:
ax = pickle.load(pickle_file)
plt.show()The latter pickle.load() fails with:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-23-0e84ab5169e3> in <module>()
15
16 with open('bla.pickle', 'rb') as pickle_file:
---> 17 ax = pickle.load(pickle_file)
18 plt.show()
/home/uni09/cosmo/cbyrohl/anaconda3/envs/py35/lib/python3.5/site-packages/matplotlib/figure.py in __setstate__(self, state)
1443 allnums = plt.get_fignums()
1444 num = max(allnums) + 1 if allnums else 1
-> 1445 mgr = plt._backend_mod.new_figure_manager_given_figure(num, self)
1446
1447 # XXX The following is a copy and paste from pyplot. Consider
AttributeError: module 'ipykernel.pylab.backend_inline' has no attribute 'new_figure_manager_given_figure'
This code was executed in a jupyter notebook (ipython 5.3)..
When executing as usual python script, it works just fine. It also works fine when dumping in Jupyter and loading in script.
