Can I use python3 in wp76xx module

41

Because I cannot run file on python3 and it get same error with python.
I have ask the wfx company they said have to fix “Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to [:<exec_prefix>]” first.
and I think it have only surface cuz’ when I press up-arrow I got “^]]A”. It should get the command before right?

42

does this help?

43

I already tried. it same result.

no idea as I am not python expert.
Currently the python3 can be run already, so this is out of the scope.

47

it have a command that have to use with python version3.6 upper.
So have can I install python3 version3.6 or upper in wp76 module

48

I have no experience on this…

Maybe you change that command to be usable in python3.5.5 will be easier

I want to import logging to using with my code. I have found the file in “./yocto/build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/python3/3.5.5-r1.0/packages-split/python3-logging” and tried to copy it in to wp76 module but still cannot import.

How can I do??

>>> import logging
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'logging'

you need to do the following two commands

scp -r ./build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/python3/3.5.5-r1.0/image/usr/lib/python3.5/logging/ root@192.168.2.2:/usr/lib/python3.5
scp -r ./build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/python3/3.5.5-r1.0/image/usr/lib/python3.5/collections/ root@192.168.2.2:/usr/lib/python3.5

I don’t know, seems already having the struct.py…

Just found that you can do this:
scp ./build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/python3/3.5.5-r1.0/image/usr/lib/python3.5/lib-dynload/_struct.cpython-35m-arm-linux-gnueabi.so root@192.168.2.2:/usr/lib/python3.5

to import distutils:

scp -r ./build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/python3/3.5.5-r1.0/image/usr/lib/python3.5/distutils/ root@192.168.2.2:/usr/lib/python3.5/

no idea for StrictVersion…
