tf.keras.backend.to_dense(tensor)
Defined in tensorflow/python/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:
python
>>> 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
