ubuntu 绘制lenet网络结构图遇到的问题汇总

Couldn't import dot_parser, loading of dot files will not be possible的问题

1 .sudo pip uninstall pyparsing

2. sudo pip install -Iv https://pypi.python.org/packages/source/p/pyparsing/pyparsing-1.5.7.tar.gz#md5=9be0fcdcc595199c646ab317c1d9a709

3. sudo pip install pydot

The directory '/home/tina/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Requirement already satisfied: pydot in /usr/lib/python2.7/dist-packages

进入python文件夹：cd ./caffe/python

   使用draw_net.py绘制lenet网络结构图

      命令：python draw_net.py ../examples/mnist/lenet_train_test.prototxt lenet.png

      如果出现错误：ImportError: No module named pydot，则再次使用pip安装，pip install pydot

      再次运行：python draw_net.py ../examples/mnist/lenet_train_test.prototxt lenet.png

      如果出现错误了：pydot.InvocationException: GraphViz's executables not found，此时需要安装graphviz，命令为sudo apt-get install graphviz

      最后再运行一次，终于成功了。在python文件夹下得到lenet.png文件了。如下图：
