1.下載Windows版Caffe
解壓後，在windows目錄下發現Caffe 2013工程
工程爲64位
2.編譯通過後，將D:\caffe-windows\python下的draw_net和D:\caffe-windows\examples\mnist\lenet_train_test.prototxt複製到d:\test下
3. cmd下輸入Python draw_net.py lenet_train_test.prototxt lenet.png
-----------------------------------------------------------------------------
D:\test>Python draw_net.py lenet_train_test.prototxt lenet.png
Traceback (most recent call last):
File "draw_net.py", line 9, in <module>
import caffe.draw
File "D:\caffe\pycaffe\caffe\draw.py", line 22, in <module>
import pydot
ImportError: No module named pydot
解決辦法：
必須先安裝 graphviz，再安裝pydot
D:\test>pip install graphviz
Collecting graphviz

解決辦法：
下載
http://www.graphviz.org/Download_windows.php windows下的graphviz安裝
Graphviz 2.30: The msi installer is again causing problems with the PATH variable. We hope to have this fixed shortly.
| graphviz | current stable release | development snapshot |
| Windows |
graphviz-2.38.msi graphviz-2.38.zip |
安裝graphviz-2.38.msi， 選擇for everyone 否則會出錯；
在path中設置graphviz路徑，否則pydot解析不出來， 如C:\Program Files (x86)\Graphviz2.38\bin
成功
