python nltk plots are not showing up

I have posted the following message in StackOverflow about my problem with graph plotting using python nltk using Matplotlib and numpy.

Advices will be tremendously helpful. Thanks in advance.

What is the result of:

python -c "import matplotlib; print matplotlib.get_backend()"
python -c "import matplotlib; print matplotlib.matplotlib_fname()"

And when you run setup.py build, what is the first block of output showing all the libraries and dependencies?

For whatever reason, it sounds like your mpl backend is not an interactive backend.

This usually happens when you're using a non interactive backend.
What's the output of plt.get_backend()?

If I understand, this should have given me “TkAgg”.

so, the backend is not working properly.

No, the backend is fine, it is just the wrong one. Most likely, when you built mpl, the libraries for the gui backends were not found.

Try:

sudo apt-get build-dep python-matplotlib

and then try building and installing mpl again.
