tf.keras.backend.is_sparse(tensor)

Defined in tensorflow/python/keras/_impl/keras/backend.py.

Returns whether a tensor is a sparse tensor.

Arguments:

  • tensor: A tensor instance.

Returns:

A boolean.

Example: python >>> from keras import backend as K >>> a = K.placeholder((2, 2), sparse=False) >>> print(K.is_sparse(a)) False >>> b = K.placeholder((2, 2), sparse=True) >>> print(K.is_sparse(b)) True
