使用pip安装安装tensorflow时出错

Question

我在cmd:pip install tensorflow==2.1.0--user上写过 它正确地加载了所有包，但最后它说：

WARNING: The scripts estimator_ckpt_converter.exe, saved_model_cli.exe, tensorboard.exe, tf_upgrade_v2.exe, tflite_convert.exe, toco.exe and toco_from_protos.exe are installed in 'C:\Users\franc\AppData\Roaming\Python\Python37\Scripts' which is not on PATH.

然后：

Successfully installed gast-0.2.2 tensorflow-2.1.0 tensorflow-estimator-2.1.0``

不管怎样，如果我写了一个代码，然后我尝试使用tensorflow，它就不起作用了

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

我得到的错误是：

Using TensorFlow backend.
ERROR:root:Internal Python error in the inspect module.
Below is the traceback from this internal error.

Traceback (most recent call last):
