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',


  • value: A tensor of numeric type.
  • name: A name for the operation (optional).
