Hey there,

I’ve been playing with your platform for months and enjoying it to bits.

However, I am struggling with virtually every deep learning’s image-related example on your hub. In other words, I cannot have the workflows running properly for one reason or another on my freshly installed 4.2.0 version.

As a last resort, I just dragged and dropped this workflow, ran it “as-is” and had the Keras Network Layer crashing with the following “ultra generic” error:

Execute failed: (“NullPointerException”): null

Thanks in advance for any help you may wish to provide,

Cheers,
-Stef
