Bins the given values for use in a histogram.
Aliases:

tf.histogram_fixed_width_bins(
values,
value_range,
nbins=100,
dtype=tf.dtypes.int32,
name=None
)
Given the tensor values
, this operation returns a rank 1 Tensor
representing the indices of a histogram into which each element of values
would be binned. The bins are equal width and determined by the arguments value_range
and nbins
.
Args:
values
: NumericTensor
.value_range
: Shape [2]Tensor
of samedtype
asvalues
.values
<=value_range
[0] will be mapped to hist[0],values
>=value_range
[1] will be mapped to hist[-1].nbins
: Scalarint32 Tensor
. Number of histogram bins.dtype
:dtype
for returned histogram.name
: Aname
for this operation (defaults to 'histogram_fixed_width').
Returns:
A Tensor
holding the indices of the binned values
whose shape matches values
.
Raises:
TypeError
: If any unsupported dtype is provided.tf.errors.InvalidArgumentError
: If value_range does not satisfy value_range[0] < value_range[1].
Examples:
# Bins will be: (-inf, 1), [1, 2), [2, 3), [3, 4), [4, inf)
nbins = 5
value_range = [0.0, 5.0]
new_values = [-1.0, 0.0, 1.5, 2.0, 5.0, 15]
with tf.compat.v1.get_default_session() as sess:
indices = tf.histogram_fixed_width_bins(new_values, value_range, nbins=5)
variables.global_variables_initializer().run()
sess.run(indices) # [0, 0, 1, 2, 4, 4]
