tf.compat.v1.math.zero_fraction, tf.compat.v1.nn.zero_fraction, `tf.compat.v2.math.zero_fraction`, `tf.compat.v2.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.
