Dropout Operation erroring

[mandar2812]

Its possible that sometime after commit e0691f8e2aed5f796d642a04922e59c3f857f5af the dropout layer stopped working (tested so far on gpu).

@mandar2812 Did you notice that the arguments to that class constructor changed? scaleOutput was added and I think you may not be accounting for that change where you call the constructor.

[mandar2812]

@eaplatanios I think this error is happening because of difference in binary version of tensorflow-scala used in my code versus the version which was used to compile DynaML. Closing this issue for now.
