נותן לי את הודעת השגיאה:

InvalidArgumentError: Nan in summary histogram for: dnn/dnn/hiddenlayer_0/activation
	 [[Node: dnn/dnn/hiddenlayer_0/activation = HistogramSummary[T=DT_FLOAT, _device="/job:localhost/replica:0/task:0/device:CPU:0"](dnn/dnn/hiddenlayer_0/activation/tag, dnn/hiddenlayer_0/Relu)]]

During handling of the above exception, another exception occurred:

מה לא תקין ב:
regressor.train(input_fn=get_input_fn(training_set), steps=5000)

?

פייתון 3.5 , tensorflow ו numpy מעודכנים .

בתודה מראש
