[PYTHON] Matplotlib Runtime Error resolution

When I tried to use matplotlib from Python3 installed by pyenv, the following error occurred.

RuntimeError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends. If you are Working with Matplotlib in a virtual enviroment see 'Working with Matplotlib in Virtual environments' in the Matplotlib FAQ

As a result of investigation, similar symptoms were found. I changed the backend of matplotlib rendering by referring to here.

The procedure is as follows.

Create a file named matplotlibrc in ~ / .matplotlib.
Add the following line to ~ / .matplotlib / matplotlibrc.

`~/.matplotlib/matplotlibrc`


backend: TkAgg

Now when I try to run the program using matplotlib again, it works.
