ImportError: cannot import name _remove_dead_weakref

I'm trying to run the sniffer per SNIFFER.md but I get an include error. I believe I followed all the steps and have all the dependencies. I noticed some of the files mentioned in the top-level have moved which makes me wonder if the .MD is out of date.

macOS 10.13.6
python 2.7.10

Re-reading the top-level readme it looks like pyspinel expects to be in the tools directory of OpenThread. I'll try moving it there when I get in the office.

@beriberikix, see this discussion.

Yes, the README being out of date was reported in #36 (admittedly a long time ago).
