What finally worked for me was to make a local matplotlibrc
file containing the directive: backend: TkAgg
.
# Within working directory where running python
vim matplotlibrc
# new file via vim, Nano, whatever
backend: TkAgg
This was useful:
import matplotlib
print matplotlib.rcParams['backend']
Other Notes:
I had also installed pyqt using Homebrew (brew install pyqt
) and copied (could just move it) into $MyVirtEnv/lib/python2.7/site-packages/
from /usr/local/lib/python2.7/site-packages/PyQt4
But when I
import matplotlib
matplotlib.use('qt4Agg')
import librosa
"Matplotlib qt-based backends require an external PyQt4, PyQt5,\n"
ImportError: Matplotlib qt-based backends require an external PyQt4, PyQt5,
or PySide package to be installed, but it was not found.
Had also tried
pip install pyside
Successfully installed pyside-1.2.4
Same error
>>> import pyside
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named pyside
Also got the following error at some point when trying to reimport matplotlib (i think).
from . import cache
ImportError: cannot import name cache
