Hi there guys!

I just installed Dataiku on MacOS (so gpu processing is not supported).

Trying to build a Deep learning model with keras and tensorflow, got an import error for tensorflow (using the default configuration/script).

Is there something I'm doing wrong?

Your help would be much appreciated.

The error:

Hello Bogdan,

It seems that you did not install the proper code environment to be able to run deep learning models.

Dataiku DSS is not shipped directly with Keras and Tensorflow, but offers the possibility to easily install them, and then use them in the visual Machine learning, to run deep learning models.

The steps to setup the appropriate code environment are detailed in the "Prerequisites" part of this tutorial:

https://www.dataiku.com/learn/guide/visual/machine-learning/deep-learning-first.html

Don't hesitate to come back to us if you have troubles installing the environment.

 

Best regards,

Nicolas Servel

Thank you!
Installed the code env and got model to work.
