Am trying to install scarlet but every time I try to import the library in a python script I will get this error: `In [1]: import scarlet

ImportError Traceback (most recent call last)

Any help would be much appreciated.

This looks lot like issue #251 at first glance. We've had similar errors when trying to import from within the scarlet repo. Please make sure you are currently outside the scarlet repo.

Unfortunately no, I get this error when trying to import from a different directory to the scarlet repo.

I have read that C++ symbol issue could be a version problem. If you are on a conda environment, this might fix the issue: conda update libgcc. If this does not work, could you please specify what specific versions of python, git, etc... you are using?

Ah so i tried to update but it told be I didn't have libgcc installed. Upon installing that and then re-installing scarlet I am now able to import it. This is awesome, thank you.
