解决方案：进入提示的网站https://www.tensorflow.org/install/errors，大多数问题都可以在这里找到。这个问题的解决方案在左侧pip中

点击上图中的Microsoft VC++ downloads下载安装包并下载，即可成功导入Tensorflow
若无法打开该网站，我这里提供某盘链接The latest supported Visual C++ downloads

下载安装之后即可，重新import之后就可以前往下一个坑了。

初学tf尝试

No module named ‘tensorflow.examples.tutorials’

常见于初学者训练mnist

ModuleNotFoundError: No module named 'tensorflow.examples.tutorials'

可先检查tensorflow文件夹中是否存在tutorials文件夹

1、在自己编译器运行的python环境的…\Python3\Lib\site-packages,该目录下有文件夹tensorflow, tensorflow_core, ensorflow_estimator。。。选择进入tensorflow_core\examples文件夹，如果文件夹下只有saved_model这个文件，则是没有tutorials。

2、前往tensorflow gayhub主页下载总文件夹然后补入缺失文件，GitHub Tensorflow
3、下载解压完毕后，在tensorflow-master\tensorflow\examples\路径下找到tutorials文件夹，把tutorials整个文件夹拷贝到上文中提到的…\Python3\Lib\site-packages\tensorflow_core\examples\中
4、重新import一下，继续踩下一个坑。

当尝试白嫖其他人的代码段时出错

AttributeError: module ‘tensorflow’ has no attribute ‘logging’

AttributeError: module ‘tensorflow’ has no attribute ‘placeholder’

常见于白嫖网上代码段，在tf2下使用了tf1的API

import tensorflow as tf
from tensorflow.examples.tutorials.mnist import input_data
tf.logging.set_verbosity(tf.logging.INFO)# 此行直接删除

# 或者替换为
import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

重新import，然后继续踩坑
