using plot_directive extension (is matplotlib installed)?

[lebedov]

According to #334, matplotlib is available on the readthedocs build server as of March 2013. When I recently tried to get the docs for a project whose documentation requires the plot_directive extension to build, however, the build complained that matplotlib isn't present. Is there some special configuration I need to enable the build process to have access to matplotlib?

Is it a Python-3 project?

[lebedov]

No - Python 2. The Python version isn't explicitly enforced anywhere in the source code or the setup.py classifiers, however.

You can try @shoyer's suggestion at the bottom of #857#issuecomment-55195387

Thanks, @ankostis - toggling Advanced Settings > Use system packages did the trick.
