Function dtype

tensorflow/python/keras/backend.py:1216–1243

Returns the dtype of a Keras tensor or variable, as a string. Arguments: x: Tensor or variable. Returns: String, dtype of `x`. Examples: ```python >>> from keras import backend as K >>> K.dtype(K.placeholder(shape=(2,4,5))) 'float32' >>> K.dtype(K.placeholder(shape=(2,
