View source on GitHub

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

Aliases:

  • tf.compat.v1.keras.backend.dtype
  • tf.compat.v2.keras.backend.dtype
tf.keras.backend.dtype(x)

Arguments:

  • x: Tensor or variable.

Returns:

String, dtype of x.

Examples:

    >>> from keras import backend as K
    >>> K.dtype(K.placeholder(shape=(2,4,5)))
    'float32'
    >>> K.dtype(K.placeholder(shape=(2,4,5), dtype='float32'))
    'float32'
    >>> K.dtype(K.placeholder(shape=(2,4,5), dtype='float64'))
    'float64'
    # Keras variable
    >>> kvar = K.variable(np.array([[1, 2], [3, 4]]))
    >>> K.dtype(kvar)
    'float32'
    >>> kvar = K.variable(np.array([[1, 2], [3, 4]]), dtype='float32')
    >>> K.dtype(kvar)
    'float32'
