Answer 1

I find an useful method.

You can add a key named name for your test phase layer, and modify the keys ntop and top just like this:

net.data = L.Data(name='data', 
                include=dict(phase=caffe_pb2.Phase.Value('TRAIN')),
                ntop=1)
net.test_data = L.Data(name='data', 
                    include=dict(phase=caffe_pb2.Phase.Value('TEST')),
                    top='data',
                    ntop=0)
