在安装好tensorflow及其相关部件后，我们可以通过以下方法去检测Tensorflow是否成功调用了GPU。

目录

本人配置注明：

本人tensorflow、CuDA等部件版本如下：

Tensorflow 2.7.0

Python 3.7.11

关于各部件版本对应问题，我会尽快发帖说明。

检测Tensorflow是否调用GPU

方法一

输入以下命令：

import tensorflow.compat.v1 as tf

sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

[！！！此处需要 import tensorflow.compat.v1 as tf 。如果直接 import tensorflow as tf，则会报错’AttributeError: module ‘tensorflow’ has no attribute ‘Session’ ‘]

方法二

输入以下命令：

import tensorflow as tf

print(tf.test.is_gpu_available())

若结果返回为True，则显示GPU可用。

以上仅个人在配置使用Tensorflow过程中所作总结，希望对大家有用。
