Ошибка TF вида max_value dict() < float()

Ошибка вида

File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/keras/layers/advanced_activations.py", line 310, in __init__

if max_value is not None and max_value < 0.:

TypeError: unorderable types: dict() < float()

Для решения проблемы надо в 310 строку добавить:

 
	    #print(max_value) 
	    if type(max_value) is dict: 
	        max_value = max_value['value'] 
	    if type(negative_slope) is dict: 
	        negative_slope = negative_slope['value'] 
	    if type(threshold) is dict: 
	        threshold = threshold['value']
