Training error

[qwdr7777]

I ran "python TrainingAnomalyDetector_public.py " ans I ran this problem:

AttributeError: 'Tensor' object has no attribute 'reshape'

I've installed keras, theano and python etc using anaconda, here's my packages info: theano 1.0.3 keras 2.2.4 python 3.7.3 Do i change packages version?

Any solution to this??

[mvk07]

Please use theano backend. This is due to tensorflow vector being passed to theano flatten.

Use this link for more information: https://keras.io/backend/

I solved the problem using

import os
os.environ['KERAS_BACKEND'] = 'theano'
