Tensorflow基本打印输出错误

Question

我是第一次尝试 tensorflow！ 我的代码是：

import tensorflow as tf
sess=tf.Session()
hello=tf.constant('Hello!')
print(sess.run(hello))

但它输出错误。我不知道如何解决它，但我不想安装另一个 tensorflow 版本。我使用 python 3.6 和 tensorflow 2.1.0

我要写更多，因为我不能发布它，我不知道该写什么。

这是完整的输出：

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/errors

for some common reasons and solutions.  Include the entire stack trace

Answer 1

tf.Session 已弃用。请改用 tf.compat.v1.Session。请参考下面的代码

import tensorflow as tf
print(tf.__version__)

with tf.compat.v1.Session() as sess:
  hello=tf.constant('Hello!')
  result = sess.run(hello)
  print(result)

输出：

2.1.0
b'Hello!'
