Python – tensorflow.math.imag()

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。

imag()用于查找张量的虚部。

Syntax: tensorflow.math.imag( input, name)

Parameters:

• input: It is a tensor. Allowed dtypes are float, double, complex64, complex128.
• name(optional): It defines the name of the operation

Returns: It returns a tensor of dtype as x.

示例 1：

Python3

# importing the library
import tensorflow as tf
 
# Initializing the input tensor
a = tf.constant([7, 8, 13, 11], dtype = tf.float64)
 
# Printing the input tensor
print('a: ', a)
 
# Calculating the result
res = tf.math.imag(a)
 
# Printing the result
print('Result: ', res)

输出：

a:  tf.Tensor([ 7.  8. 13. 11.], shape=(4, ), dtype=float64)
Result:  tf.Tensor([0. 0. 0. 0.], shape=(4, ), dtype=float64)

示例 2：

Python3

# Importing the library
import tensorflow as tf
 
# Initializing the input tensor
a = tf.constant([2 + 4j, 8 + 7j, 14 + 5j], dtype = tf.complex128)
 
# Printing the input tensor
print('a: ', a)
 
# Calculating the result
res = tf.math.imag(a)
 
# Printing the result
print('Result: ', res)

输出：

a:  tf.Tensor([ 2.+4.j  8.+7.j 14.+5.j], shape=(3, ), dtype=complex128)
Result:  tf.Tensor([4. 7. 5.], shape=(3, ), dtype=float64)
