一、tensorflow
，pip下载速度太慢，加上pip源
eg:pip install -i http://pypi.douban.com/simple/ --trusted-host=pypi.douban.com/simple tensorflow-gpu==1.12.0

1，ERROR: Cannot uninstall ‘wrapt’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
方法1：输入 pip install -U --ignore-installed wrapt enum34 simplejson netaddr

2，ImportError: DLL load failed: A dynamic link library (DLL) initialization routine failed.Failed to load the native TensorFlow runtime.See https://www.tensorflow.org/install/errorsfor some common reasons and solutions. Include the entire stack traceabove this error message when asking for help
使用pip下载成功tensorflow后，在当前环境中使用python进行验证tensorflow是否安装成功。import tensorflow as tf
结果：冒出了一个错误，显示无法找到该模块。以及一连串的回溯失败，这下面是末尾的异常报错。以及一连串的回溯失败，这下面是末尾的异常报错。ImportError: DLL load failed: A dynamic link library (DLL) initialization routine failed.Failed to load the native TensorFlow runtime.See https://www.tensorflow.org/install/errorsfor some common reasons and solutions.

方法1：
首先，conda install tensorflow==1.12.0
然后再，pip install tensorflow==1.12.0
亲测好使
方法2：pip install protobuf
未实验，查询解答，众说纷纭，记录一下
