When you source environment-setup-armv7ahf-vfp-neon-oe-linux-gnueabi it points python to the e310/ARM version of Python that comes to the SDK. Since gr_modtool needs to run on your host system to set up a new OOT module, the ARM version of python won't work for you. Your best bet is to open a new terminal, source your e310/setup_env.sh, and then develop your OOT module as needed. Only source environment-setup-armv7ahf-vfp-neon-oe-linux-gnueabi at the end when it's time to build and install your OOT module into your cross-compile build. Another alternative, do development and testing of your OOT module on a pybomb prefix set up for x86 gnuradio and just copy-paste-make-install the directory to your cross-compile prefix at the end.
