Hello,

I am getting this when trying to execute any Keras sample

I have Python 3.6.8 (tried 3.7 aswell), every package installed, I even pass the tests from preference's tabs (see screenshots attached). I don't know what to do, I reinstalled a few times with different versions and it's still not working.

Hi @painAI

Keras extension is having issues in RM. With new version 9.1 there is a matured native deep learning operator (extension need to be installed from market place) which you can use to train and test algorithms. You can try some samples here. 



You can go through the link below to learn more about this.

Also, here is the link for keras on RapidMiner, see the versions of python and extensions for the type of OS used.
