Ludwig: ImportError: Python is not installed as a framework.

[tweak-wtf]

Hey people,
I´ve followed your instructions for installing ludwig manually.
Unfortunately when I try to run the binary i get an error message telling me that python isn´t installed as a framework.
Here is the stack trace I get...

Traceback (most recent call last):

ImportError: 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 using (Ana)Conda please install python.app and replace the use of 'python' with 'pythonw'. See 'Working with Matplotlib on OSX' in the Matplotlib FAQ for more information.

I´m on macOS Mojave 10.14 running Python 3.6.5.
Maybe you know a fix for this?

Meanwhile I´ve just pip-installed ludwig in another venv which works like a charm.

try :
conda install matplotlib

[tweak-wtf]

will try, thanks!
But I already pip-install all requirements. so matplotlib is already installed at version 3.0.2

Hi @tony-dorfmeister , this issue should not exist in matplotlib >= 3.0. Anyway, I also pushed a fix that should solve it also for older versions of matplotlib. Can you please try again using the latest version of Ludwig on master?

Works like a charm. Thanks! :)
