Combining Pre-trained Left and Right nets into a single joint model

combine.py

import numpy as np
import sys, os

# Edit the paths as needed:
caffe_root = '../caffe/'
sys.path.insert(0, caffe_root + 'python')

import caffe

# Path to your combined net prototxt files:
combined_model_root_path = './models/combined_net/'
l_model_root_path = './models/left/2015-07-20/'
r_model_root_path= './models/right/2015-07-20/'

# The pre-trained Caffemodel files:
lnet_file = '_iter_50000.caffemodel'
rnet_file = '_iter_60000.caffemodel'
# Their respective prototxt files:
lnet_proto = 'net.prototxt'
rnet_proto = 'net.prototxt'

# Chdir if your prototxt files specify your training and testing files
# in relative paths:
os.chdir(l_model_root_path)
lnet = caffe.Net(lnet_proto, lnet_file, caffe.TRAIN)

os.chdir(r_model_root_path)
rnet = caffe.Net(rnet_proto, rnet_file, caffe.TRAIN)

os.chdir(combined_model_root_path)
comb_net = caffe.Net('net.prototxt', caffe.TRAIN)

# The layers you want to combine into the new caffe net:
layer_names = ['ff1', 'ff2']

# The two nets we have already loaded:
nets = {
    'l': lnet,
    'r': rnet,
}

# For each of the pretrained net sides, copy the params to
# the corresponding layer of the combined net:
for side, net in nets.items():
    for layer in layer_names:
        W = net.params[layer][0].data[...] # Grab the pretrained weights
        b = net.params[layer][1].data[...] # Grab the pretrained bias
        comb_net.params['{}_{}'.format(side, layer)][0].data[...] = W # Insert into new combined net
        comb_net.params['{}_{}'.format(side, layer)][1].data[...] = b 

# Save the combined model with pretrained weights to a caffemodel file:
comb_net.save('pretrained.caffemodel')

I wonder the two pre-trained model are the same networks or different?

I am not able to load two nets, my terminal becomes unresponsive. Is there anything to be taken care of? The following codes prints loaded rgb net and then tries to load the second net . After printing out the following, it hangs

os.chdir(combined_model_root_path)
net_rgb = caffe.Net(net_proto, net_file, caffe.TRAIN)
print("loaded rgb net")
comb_net = caffe.Net('pose_train_test_rgb.prototxt', caffe.TRAIN)
print("loaded comb net")
