I run the HED on Ubuntu+caffe+CPU on computer and came across the following errors when make runtest, I ignoreed them and went on, It happened to ImportError: No module named _caffe, what should I do ?

@exampen I think the problem "ImportError: No module named _caffe" happened because you haven't set up pycaffe correctly, you can make it with "make pycaffe -j4"

Thanks, and are you sure that I should make pycaffe before make runtest?

@exampen no, I think there is no relationship between "make pycaffe" and "make runtest". You can run the test python scripts well after "make pycaffe" even you failed to "make runtest", but I'm not sure whether there will be errors when training.
