如何解决不能绘制网络模型，报错protobuf

绘制网络模型，总显示这样的错误：

AttributeError: 'google.protobuf.pyext._message.RepeatedScalarConta' object has no attribute '_values'

具体内容见下：

caffe:>> ./python/draw_net.py ./examples/cifar10/cifar10_quick_train_test.prototxt ./visualization.pngDrawing net to ./visualization.pngTraceback (most recent call last):  File "./python/draw_net.py", line 45, in <module>    main()  File "./python/draw_net.py", line 41, in main    caffe.draw.draw_net_to_file(net, args.output_image_file, args.rankdir)  File "/home/andre/caffe/python/caffe/draw.py", line 222, in draw_net_to_file    fid.write(draw_net(caffe_net, rankdir, ext))  File "/home/andre/caffe/python/caffe/draw.py", line 204, in draw_net    return get_pydot_graph(caffe_net, rankdir).create(format=ext)  File "/home/andre/caffe/python/caffe/draw.py", line 151, in get_pydot_graph    node_label = get_layer_label(layer, rankdir)  File "/home/andre/caffe/python/caffe/draw.py", line 94, in get_layer_label    layer.convolution_param.kernel_size[0] if len(layer.convolution_param.kernel_size._values) else 1,AttributeError: 'google.protobuf.pyext._message.RepeatedScalarConta' object has no attribute '_values'

这是由于你的protobuf的版本不对造成的，用pip install protobuf安装的版本号默认是最新的3.2.0。但是caffe不支持高于3.0.0版本的protobuf.

解决方法：卸载当前protobuf。（pip uninstall protobuf）

再指定安装低版本的，版主这里用的是2.5.0（pip install protobuf==2.5.0）

结束后再编译一遍pycaffe，就可以成功画出网络结构图了。

如果实在不能成功，也不要灰心，版主还提供在线网页绘制caffe网络结构图的方法，其实更简洁方便：
