I was following this instruction to train/run SSD and in step 3, when executing 'create_data.sh', I get the following error message:

Traceback (most recent call last):
  File "/home/USR/Desktop/caffe-ssd/data/VOC0712/../../scripts/create_annoset.py", line 103, in <module>
    label_map = caffe_pb2.LabelMap()
AttributeError: module 'caffe.proto.caffe_pb2' has no attribute 'LabelMap'

I'm running python 3.7.3 on ubuntu 18. I would be glad about any ideas what went wrong. Thank you!
