Using coda, deepreplay version is 0.1.2a2 keras version is 2.4.0

same error here

Same error here too. Running on Colab. Any answer?

Hi,

The error arises from the default versions used by Colab nowadays which are, unfortunately, not compatible with the code I wrote for DeepReplay years ago. If is still possible to run the examples, though, if you downgrade the versions of some packages.

Paste the lines below into a new cell, run it, and restart the kernel, and you should be able to run the examples.

!pip install keras==2.2.0 !pip install tensorflow==1.15.5 !pip install keras_applications==1.0.7

Hope it helps. Best, Daniel

Thanks, that fixed it. Luciano.
