Tensorflow——更新到1.12.0报错处理(用安装指定版本命令装回以前的)

博主因需要安装skimage，使用了命令：

pip install -U --ignore-installed scikit-image

在安装的时候发现如下一行内容：

tensorflow 1.10.0 has requirement numpy<=1.14.5,>=1.13.3, but you'll have numpy 1.16.0 which is incompatible.

意思是我现在使用的tensorflow所需的numpy版本是不超过1.14.5的，而为了安装scikit-image必须再给我整一个1.16.0的numpy，于是我运行如下代码更新了tensorflow：

pip install --upgrade tensorflow

既然你有升级需求，我偶尔也满足一下你，应该不会出问题的……

才怪！

接下来，我的pycharm瞬间多了很多红波浪线，之前能运行的代码也报废了，经过排查，发现以下两个语句会报错：

>>> import tensorflow as tf
Traceback (most recent call last):

网上查找各种解决方法……根本就没有解决方法，唯一搜到的也是他人的求助而无人回答………………

最终不得不尝试运行：

pip install tensorflow==1.10.0

成功将tensorflow更换成以前使用的版本，程序报错也消失了，送了一大口气。

这件事告诉我，

不轻易做没需求的更新！

尝试新事物前请记当前状态为“断点”，以便需要时回溯。
