# tf.nn.zero_fraction(value, name=None)

### tf.nn.zero_fraction(value, name=None)

Returns the fraction of zeros in value.

If value is empty, the result is nan.

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

    z = tf.Relu(...)
summ = tf.contrib.deprecated.scalar_summary('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.
