Seems like you have python-msgpack version less than 0.3.0.
Check this: python -c 'import msgpack; print(msgpack.version)'
Or: pip list | grep msgpack

from cocaine-framework-python.

python -c 'import msgpack; print(msgpack.version)'
gives me ( 0.4.0 )

i reinstalled pip, log changed

As far as I understand you should install libmsgpack-dev and reinstall msgpack for python. Without libmsgpack-dev pip installs only pure python implementation (fallback.py).
