All of a sudden I started getting this error when trying to use accessible_output2.

>>> import accessible_output2.outputs.sapi5
>>> tts == accessible_output2.outputs.sapi5.SAPI5()
Traceback (most recent call last):

I found a "fix" by deleting c:\users\sklut\AppData\Local\Temp\gen_py\3.7 but I don't know what caused it or how to keep it from happening in the future.
