解决方案

看起来 Tensorflow 安装不正确，请卸载现有的 Tensorflow 并按照说明安装新的，

使用画中画

#Install tensorflow using pip virtual env 
$pip install virtualenv
$virtualenv tf   # tf is virtual env name
$source tf/bin/activate
tf $ pip install tensorflow
tf $ python
>>import tensorflow as tf
>>tf.__version__
2.5.0

使用蟒蛇

1. Set Up Anaconda Environments
conda create --name tf_env python=3

2. Activate the new Environment
source activate tf_env

3. Install Tensorflow
pip install tensorflow
