Have installed matplotlib 3 times still get error: ImportError: No module named backends.backend_wxagg
have completely installed and re installed matplotlib 3 times 3 different ways if i open idle it will let me add import matplotlib but as soon as i try to run sample code from the matplotlib website i get errors, always when using the convention:
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas from matplotlib.path import Path from matplotlib.spines import Spine from matplotlib.projections.polar import PolarAxes from matplotlib.projections import register_projection
the from statement can be anything the only hting that follows is an errors saying

have tried with several different versions of matplotlib and still same result. suggestions?
It sounds like there is a conflict related to the system python installation. Perhaps the system python does not see the matplotlib installation. You may also want to check the permissions of the installed files. What operating system are you running and what method are you using for installing matplotlib (pip, apt-get, setup.py, building binaries)?
Try opening a python shell and simply importing matplotlib:
>>> import matplotlib as mpl
python, In my code, I need to check whether the matplotlib backend has import matplotlib if not matplotlib.get_backend() == 'WXAgg': With matplotlib 2.2.3: matplotlib 3.0.0 has backend issues only when installed by conda #10219 In that specific case you'll get an ImportError, which is just fine with me. pip uninstall matplotlib pip install matplotlib --no-binary=matplotlib This will solve your problem, provided that you already installed gtk2 with sudo apt-get install python-gtk2-dev As you want to use the GTKAgg backend, Using pip may prove useful in the future to freeze matplotlib at a version where it is supported (the deprecation warning states it will be dropped in 3.0):
I had the same problem. First I checked out the
sys.path to see what are the folders that it searches for the installed packages.
my result was something like this.

Which is not the one from anaconda and it is older. I am not sure if it would be better to just remove this folder completely.
However, as I understand, python first searched there and found a matplotlib package which was outdated. I simply changed the name of the `matplotlib' to something like 'matplotlib_test' and then the library is installed from one of the anaconda folders and the problem is solved.
I wonder if I should delete the "roaming" folder to avoid similar other problems.

The errors you posted are unrelated. The first one is due to you selecting a backend that is not meant for interactive use, i.e. agg. You can still use (and should use) those for the generation of plots in scripts that don’t require user interaction.
