TensorFlow 1 version View source on GitHub

Returns the dtype of a Keras tensor or variable, as a string.

tf.keras.backend.dtype(x)

Arguments:

  • x: Tensor or variable.

Returns:

String, dtype of x.

Examples:

>>> tf.keras.backend.dtype(tf.keras.backend.placeholder(shape=(2,4,5)))
'float32'
>>> tf.keras.backend.dtype(tf.keras.backend.placeholder(shape=(2,4,5),
...                                                     dtype='float32'))
'float32'
>>> tf.keras.backend.dtype(tf.keras.backend.placeholder(shape=(2,4,5),
...                                                     dtype='float64'))
'float64'
>>> kvar = tf.keras.backend.variable(np.array([[1, 2], [3, 4]]))
>>> tf.keras.backend.dtype(kvar)
'float32'
>>> kvar = tf.keras.backend.variable(np.array([[1, 2], [3, 4]]),
...                                  dtype='float32')
>>> tf.keras.backend.dtype(kvar)
'float32'
