NVIDIA DIGITS 5.1-dev学习笔记之安装过程记录：Windows10 x64位系统 、 MicroSoft Caffe Master、CUDA 8.0 、Python 2.7

今天成功在windows下配置成功了英伟达的DIGITS，记录一下问题解决过程。
环境简介： Windows10_x64 CUDA 8.0 / CUDA 7.5 Python2.7 Microsoft-Caffe-master

完全按照此步骤操作不会出现问题，尤其是 关于python package的版本问题，详见DIGITS-master目录下的requirements.txt：

Pillow>=2.3.0,<=3.1.2
numpy>=1.8.1,<=1.11.0
scipy>=0.13.3,<=0.17.0
protobuf>=2.5.0,<=2.6.1
six>=1.5.2,<=1.10.0
requests>=2.2.1,<=2.9.1
gevent>=1.0,<=1.1.0
gevent-websocket0.9.3
Flask0.10.1
Flask-WTF>=0.11,<=0.12
wtforms>=2.0,<=2.1
Flask-SocketIO2.6
setuptools>=3.3,<=20.7.0
lmdb0.87
h5py>=2.2.1,<=2.6.0
pydot>=1.0.28,<=1.0.29
psutil>=1.2.1,<=3.4.2
matplotlib>=1.3.1,<=1.5.1
scikit-fmm>=0.0.9

版本号一定确保和上述一致。

BUG 1 : 与google.protobuf 有关

**
我记得是在加载from google.protobuf import _symbol 指令时（大概就是这个指令吧），问题是由于我原来安装的时ptotobuf 2.5.0，版本有点低，然后我更新到2.6.1后，就没问题了。ptotobuf在windows下的python支持编译方法请自行google。

BUG 2 : 当我运行时

I:\DIGITS-master>python -m digits

A valid Caffe installation was not found on your system.
Use the envvar CAFFE_ROOT to indicate a valid installation.
Traceback (most recent call last):

然后，我看了下caffe.py这个文件。
caffe.py：
关键信息我都红色标记了。
