This looks like a bug somewhere if libboost-python1.62.0 changed from python3.5
to python3.6 on a rebuild when the default python3 version changed, thus
changing the shared library shipped by it as it embeds the python version,
without a rebuild forced on its users. The bug is not necessarily in boost, it
could be in caffe as it got rebuilt with python3.6 and yet it picked up a
dependency on libboost_python-py35.so.1.62.0. We may need stricter dependencies
so we detect that rebuilds are needed, plus we may want to fail builds when such
inconsistencies are found. E.g. see the mixed 3.5 and 3.6 in here:

Something looks fishy there.
