tf.keras.backend.to_dense

tf.keras.backend.to_dense(tensor)

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

Converts a sparse tensor into a dense tensor and returns it.

Arguments:

• tensor: A tensor instance (potentially sparse).

Returns:

A dense tensor.

Examples:

>>> from keras import backend as K
>>> b = K.placeholder((2, 2), sparse=True)
>>> print(K.is_sparse(b))
True
>>> c = K.to_dense(b)
>>> print(K.is_sparse(c))
False
