Python | tensorflow.math.Bessel_i0()方法
原文:https://www.geesforgeks.org/python-tensorflow-math-Bessel_i0-method/
TensorFlow 是谷歌为开发机器学习模型和深度学习神经网络而设计的开源 python 库。
bessel_io()是 TensorFlow 数学模块中的方法。该方法用于计算张量的元素贝塞尔 i0。
Syntax:
tensorflow.math.bessel_i0(
input, name
)
Argument:
1\. input: It's a tensor or SparseTensor for which element wise Bessel iO
need to be calculated. Allowed dtypes are half, float32, float64\.
2\. name: It is an optional argument that defines the name for the operation.
Return:
A Tensor if Tensor is given as input otherwise SparseTensor having the same dtype as input.

# importing the library
import tensorflow as tf
# initializing constant tensor
a = tf.constant([-1.5, 3 ], dtype=tf.float64)
# calculating bessel io
b = tf.math.bessel_i0(a)
# printing the input
print('Input: ',a)
# printing the output
print('Output: ',b)
输出:
Input: tf.Tensor([-1.5 3\. ], shape=(2,), dtype=float64)
Output: tf.Tensor([1.64672319 4.88079259], shape=(2,), dtype=float64)
例 2:
本示例使用 dtype 为 int32 的 tensor，这会引发错误。只允许使用 dtype half、float32、float64 的张量。

# importing the library
import tensorflow as tf
# initializing constant tensor with dtype int32
a = tf.constant([1 , 3 ], dtype=tf.int32)
# printing the input
print('Input: ',a)
# calculating bessel io
b = tf.math.bessel_i0(a)
输出:
Input: tf.Tensor([1 3], shape=(2,), dtype=int32)
