tf.compat.v1.math.zero_fraction, tf.compat.v1.nn.zero_fraction

tf.math.zero_fraction(
    value, name=None
)

If value is empty, the result is nan.

This is useful in summaries to measure and report sparsity. For example,

    z = tf.nn.relu(...)
    summ = tf.compat.v1.summary.scalar('sparsity', tf.nn.zero_fraction(z))

Args
`value`	A tensor of numeric type.
`name`	A name for the operation (optional).

Returns
The fraction of zeros in `value`, with type `float32`.
