One of the possible reasons is undefined reference/symbol in the OOT's shared object (.so) file. Go to the source directory of lora_sdr, open `python/__init__.py`, change ImportError to ModuleNotFoundError, save, rebuild, reinstall, run your flowagraph and hopefully you are going to get some more information about what is wrong. Provide the full output if you need help resolving this.
