is pyhton version problem?

Same situation. I am on Debian Strech host, trying to use gef with arm-none-eabi-gdb-py or arm-none-eabi-gdb. Error is the same for both of them. Host gdb loads gef with no problems.

arm-none-eabi-gdb-py it only supports python2.7, so should modified gdbinit-gef.py:

Yeah, it looks like a Python2 related thing, and since last Jan. we don't support Python2 any longer I'm closing this issue.
Re-open with more information about your setup if you think it's a mistake.
