测试tensorflow安装成功

• 在命令行中输入以下命令测试tensorflow安装是否成功

 import tensorflow as tf
 tf.compat.v1.disable_eager_execution()
 x=tf.constant(1)

#如果这里报错 Could not load dynamic library ‘nvcuda.dll’; dlerror:nvcuda.dll not found或者Could not load dynamic library’cudart64_110.dll’; dlerror: cudart64_110.dll not found
去下载cudart64_110.dll 文件，官方下载地址：https://www.dll-files.com/cudart64_110.dll.html，解压会出现如下文件：cudart64_110.dll； 把cudart64_110.dll复制粘贴到C:\Windows\System32里就可以了之后，再重新输入x=tf.constant(1)

 x=tf.constant(1)
 y=tf.constant(2)
 z=x+y

#如果这里报错To enable them in other operations, rebuild TensorFlow with
the appropriate compiler flags.就加下面两行

 **import os
 os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'**

sess=tf.compat.v1.Session()
print(sess.run(z))

结果：3
