tf.math.count_nonzero Computes number of nonzero elements across dimensions of a tensor. (deprecated arguments) (deprecated arguments)

tf.math.count_nonzero(
input_tensor=None, axis=None, keepdims=None, dtype=tf.dtypes.int64, name=None,
reduction_indices=None, keep_dims=None, input=None
)
Warning: SOME ARGUMENTS ARE DEPRECATED: `(keep_dims)`

. They will be removed in a future version. Instructions for updating: keep_dims is deprecated, use keepdims instead Warning: SOME ARGUMENTS ARE DEPRECATED: `(axis)`

. They will be removed in a future version. Instructions for updating: reduction_indices is deprecated, use axis instead Reduces `input_tensor`

along the dimensions given in `axis`

. Unless `keepdims`

is true, the rank of the tensor is reduced by 1 for each entry in `axis`

. If `keepdims`

is true, the reduced dimensions are retained with length 1.

If `axis`

has no entries, all dimensions are reduced, and a tensor with a single element is returned.

Note: Floating point comparison to zero is done by exact floating point equality check. Small values are not rounded to zero for purposes of the nonzero check.
For example: x = tf.constant([[0, 1, 0], [1, 1, 0]])
tf.math.count_nonzero(x) # 3
tf.math.count_nonzero(x, 0) # [1, 2, 0]
tf.math.count_nonzero(x, 1) # [1, 2]
tf.math.count_nonzero(x, 1, keepdims=True) # [[1], [2]]
tf.math.count_nonzero(x, [0, 1]) # 3
Note: Strings are compared against zero-length empty string `""`

. Any string with a size greater than zero is already considered as nonzero.
For example: x = tf.constant(["", "a", " ", "b", ""])
tf.math.count_nonzero(x) # 3, with "a", " ", and "b" as nonzero strings.
Args
`input_tensor`

The tensor to reduce. Should be of numeric type, `bool`

, or `string`

.
`axis`

The dimensions to reduce. If `None`

(the default), reduces all dimensions. Must be in the range `[-rank(input_tensor), rank(input_tensor))`

.
`keepdims`

If true, retains reduced dimensions with length 1.
`dtype`

The output dtype; defaults to `tf.int64`

.
`name`

A name for the operation (optional).
`reduction_indices`

The old (deprecated) name for axis.
`keep_dims`

Deprecated alias for `keepdims`

.
`input`

Overrides input_tensor. For compatibility.

Returns The reduced tensor (number of nonzero values).
