StopIteration: points is not a numpy array, neither a scalar

Hi again, I am using conda and I installed opencv-python as it is written in this issue, but I didn't remove my previous opencv.
Now, I am getting the following error, is it possible that it is because of an opencv conflict?!

Epoch 1/20

I've seen this error yesterday too .. seems to be caused by Keras 2.1.0. For now, install Keras 2.0.9 to fix this issue.

For reference, this is what caused it : keras-team/keras#8056 (review)

Yesss, thank you so much.
I installed the 2.0.9 version by conda install -c conda-forge keras and it works.
