首先说明Windows7笔记本可以跑的起TensorFlow-GPU版的最低软硬件要求：
– 显卡 GTX 750M,GPU版TensorFlow要求显卡算力在3.0及以上；
– CUDA8.0.44，其他版本会出问题；
– cudnn6.0 ;
–TensorFlow-GPU1.4.0更高或者更低版本都回出问题；
–Python3.6.x，其他版本不确定能不能正常运行TensorFlow；
问题1：CUDA版本与TensorFlow版本要求不搭配导致 ImportError: No module named ‘_pywrap_tensorflow_internal’
cuda版本不对会报如下错误：

本人电脑GPU是GTX 750M根据官网的说明，需要安装这个版本：
可以从英伟达官网下载。更高版本的cuda经试验是不能被TensorFlow1.4.0正确调用的。请不要选择更高版本的cuda。本事尝试了这个版本可以正常使用（这是下载链接）。
另外，在安装cuda后务必检查Visual C++ Redistributable for Visual Studio 2015是否安装，可在操作系统控制面板查看，如果没有安装需要去微软官网下载（这是下载链接）。
问题2：win7跑tensorflow_gpu的python测试程序时，电脑总是卡死
解决方法：将电脑显卡驱动更新至最新版本，并重启启动电脑即可。
