Python – tensorflow.histogram_fixed_width()

TensorFlow 是由 Google 设计的开源Python库，用于开发机器学习模型和深度学习神经网络。

histogram_fixed_width()用于查找直方图值。

Syntax: tensorflow.histogram_fixed_width( values, value_range, nbins, dtype, name )

Parameters:

• values: It is a numeric Tensor.
• value_range: It is a Tensor of shape [2] with same dtype as values.
• nbins(optional): It defines the number of bins in histogram. Default value is 100.
• dtype(optional): It defines the dtype of returned histogram. Default value is int32.
• name(optional): It defines the name of the operation.  

Returns: It returns a Tensor of histogram values.

示例 1：

Python3

# Importing the library
import tensorflow as tf
  
# Initializing the input
nbins = 6
value_range = [0.0, 6.0]
new_values = [3.0, 0.0, 1.5, 2.0, 5.0, 15]
  
# Finding histogram values
hist = tf.histogram_fixed_width(new_values, value_range, nbins)
  
# Printing the result
print("res: ", hist.numpy())

输出：

res:  [1 1 1 1 0 2]

示例 2：

Python3

# Importing the library
import tensorflow as tf
  
# Initializing the input
nbins = 6
value_range = [0.0, 4.0]
new_values = [3.0, 0.0, 1.5, 2.0, 5.0, 1.0]
  
# Finding histogram values
hist = tf.histogram_fixed_width(new_values, value_range, nbins)
  
# Printing the result
print("res: ", hist.numpy())

输出：

res:  [1 1 1 1 1 1]
