Anaconda: Unable to import pylab
13,176
Just had this problem and it was related to which qt backend matplotlib was trying to use, try:
import PyQt4
If you don't have PyQt4 you probably have PySide
import PySide
If this is the case you need to set the matplotlib.rcParams['backend.qt4'] == 'PySide'
not 'PyQt4'
. You can also do this in your matplotlibrc file (~/.matplotlib/matplotlibrc)
# find and change line:
backend.qt4 : PySide
Note: if you don't have the matplotlibrc file you can copy it from the matplotlib source directory
import os
import matplotlib
mpl_dir = os.path.dirname(matplotlib.__file__)
os.system("cp {}/mpl-data/matplotlibrc ~/.matplotlib/".format(mpl_dir))

I am unable to
import pylab
using the latest version of Anaconda (Linux 64 bit). Other packages seem to work fine. (Note: I don't havesudo
access)In [1]: import pylab as pl --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-6-2cf12a0af6ff> in <module>() ----> 1 import pylab as pl /home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/pylab.py in <module>() ----> 1 from matplotlib.pylab import * 2 import matplotlib.pylab 3 __doc__ = matplotlib.pylab.__doc__ /home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/matplotlib/pylab.py in <module>() 267 from numpy.linalg import * 268 --> 269 from matplotlib.pyplot import * 270 271 # provide the recommended module abbrevs in the pylab namespace /home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/matplotlib/pyplot.py in <module>() 96 97 from matplotlib.backends import pylab_setup ---> 98 _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() 99 100 /home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/matplotlib/backends/__init__.pyc in pylab_setup() 23 backend_name = 'matplotlib.backends.%s'%backend_name.lower() 24 backend_mod = __import__(backend_name, ---> 25 globals(),locals(),[backend_name]) 26 27 # Things we pull in from all backends /home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/matplotlib/backends/backend_qt4agg.py in <module>() 11 12 from backend_agg import FigureCanvasAgg ---> 13 from backend_qt4 import QtCore, QtGui, FigureManagerQT, FigureCanvasQT,\ 14 show, draw_if_interactive, backend_version, \ 15 NavigationToolbar2QT /home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/matplotlib/backends/backend_qt4.py in <module>() 23 figureoptions = None 24 ---> 25 from qt4_compat import QtCore, QtGui, _getSaveFileName, __version__ 26 27 backend_version = __version__ /home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/matplotlib/backends/qt4_compat.py in <module>() 34 # Now perform the imports. 35 if QT_API in (QT_API_PYQT, QT_API_PYQTv2): ---> 36 import sip 37 if QT_API == QT_API_PYQTv2: 38 if QT_API_ENV == 'pyqt': ImportError: No module named sip
If I try
> conda install sip
I get:
Error: No packages found matching: sip
I also get errors with:

Any thoughts on why?

tacaswell over 10 yearsYou seem to not have
PyQt
installed properly, use a different backend. -
Josh over 10 yearsThanks @tcaswell. What other backend would you recommmend?
-
tacaswell over 10 yearsThe snarky (but mostly correct) answer is which ever one you have the dependencies installed for. Try
tkagg
,wxagg
, orgtk3agg
