issue with clear_session() in ALA DP JUPYTER #30

Closed dlbeveridge closed 5 years ago

dlbeveridge commented 5 years ago

Working through Alanine_dipeptide.ipynb

AT "Run several model iterations...." encountered a problem with tensorflow command:

clear_session()

Thoughts on this??

Diagnostic:

UnboundLocalError Traceback (most recent call last)

I found a lot of similar issues on stack overflow that point to a compatibility issue between tensorflow and python 3.7 . What version of python are you using?

Luca,

Thanks. I am on python 3.7.3 so that may be the problem.
