So you are using gnuradio 3.8, how did you installed it - manually, pybombs or from the gnuradio's PPA?
Which gr-gsm version are you trying to compile and from which git repository/branch?

The gr-gsm's master branch still does not support gnuradio 3.8. We are working on porting it in https://github.com/ptrkrysik/gr-gsm/issues/475
For now you need to checkout and build the `maint-3.8` branch from my fork - https://github.com/velichkov/gr-gsm/tree/maint-3.8

How did you install gr-osmosdr?

Note that gr-osmosdr from the bionic's apt repository does not support gnuradio 3.8 so you need to install it manually from one of the forks - https://github.com/igorauad/gr-osmosdr/tree/gr3.8 Also note that having multiple versions (one from the apt repo in /usr and second one installed manually in /usr/local) could lead to many hard to investigate problems. So if you want to use gnuradio 3.8 my advice is to remove all gnuradio and gr-osmosdr packages installed from the bionic's apt repository.

The manual installation of gr-omosdr will place it's python files in /usr/local/lib/python3/dist-packages/ and this path is not in the default search paths so you w need to add it to your PYTHONPATH

export PYTHONPATH=/usr/local/lib/python3/dist-packages/:$PYTHONPATH

P.S.
In the future you may post gr-gsm related questions to the gr-gsm's mailing list as well https://github.com/ptrkrysik/gr-gsm/#mailing-list
