1.在执行sudo make all -j4的时候，出现了以下错误，报错提示说在caffe-segnet/src/caffe/layers的路径下的contrastive_loss_layer.cpp出错

2.
在执行sudo python ./Scripts/test_segmentation_camvid.py --model Models/segnet_basic_inference.prototxt --weights ./Example_Models/segnet_weights_driving_webdemo.caffemodel --iter 1的时候出现的错误：
解决方案：
安装需要用到的库：
sudo apt-get install python-matplotlib
sudo apt-get install python-scipy
sudo apt-get install python-opencv
sudo apt-get install python-protobuf
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
sudo python get-pip.py
sudo pip install -U scikit-image
3.后面又出现了这个错误：
Traceback (most recent call last):
File "./Scripts/test_segmentation_camvid.py", line 14, in <module>
import caffe
ImportError: No module named caffe
解决方案：
发现这里在配置caffe_root路径时少打了个/，正确的应该是'xxx/cafe-segnet/'
