I try to visualize the network.But I get the errors.

AttributeError: type object 'LayerParameter' has no attribute 'LayerType'

I check the caffe caffe_pb2.py and get this:

_LAYERPARAMETER_LAYERTYPE = descriptor.EnumDescriptor(
name='LayerType',
full_name='caffe.LayerParameter.LayerType',
filename=None,
file=DESCRIPTOR,

Below is my use case:

import caffe
from caffe import draw
from caffe.proto import caffe_pb2

enddef

net = caffe_pb2.NetParameter()
with open('model/_iter_500000.caffemodel','rb') as f:
net.ParseFromString(f.read())
print net.name
draw.draw_net_to_file(net,'network.png')
