Return histogram of values.
Given the tensor `values`, this operation returns a rank 1 histogram counting the number of entries in `values` that fall into every bin. The bins are equal width and determined by the arguments `value_range` and `nbins`.
# 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.get_default_session() as sess:
hist = tf.histogram_fixed_width(new_values, value_range, nbins=5)
variables.global_variables_initializer().run()
sess.run(hist) => [2, 1, 1, 0, 2]

Public Methods
public Output <U> asOutput ()
Returns the symbolic handle of a tensor.
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.
public static HistogramFixedWidth <U> create ( Scope scope, Operand <T> values, Operand <T> valueRange, Operand <Integer> nbins, Class<U> dtype)
Factory method to create a class wrapping a new HistogramFixedWidth operation.
Parameters
scope | current scope |
---|---|
values | Numeric `Tensor`. |
valueRange | Shape [2] `Tensor` of same `dtype` as `values`. values <= value_range[0] will be mapped to hist[0], values >= value_range[1] will be mapped to hist[-1]. |
nbins | Scalar `int32 Tensor`. Number of histogram bins. |
Returns
- a new instance of HistogramFixedWidth
public static HistogramFixedWidth <Integer> create ( Scope scope, Operand <T> values, Operand <T> valueRange, Operand <Integer> nbins)
Factory method to create a class wrapping a new HistogramFixedWidth operation using default output types.
Parameters
scope | current scope |
---|---|
values | Numeric `Tensor`. |
valueRange | Shape [2] `Tensor` of same `dtype` as `values`. values <= value_range[0] will be mapped to hist[0], values >= value_range[1] will be mapped to hist[-1]. |
nbins | Scalar `int32 Tensor`. Number of histogram bins. |
Returns
- a new instance of HistogramFixedWidth
