@danintel, I'm using the version from ubuntu repo grpcio-tools==1.21.1, both for generating on shell and reading services.
I'm not sure about the necessity to use the python3-grpcio-tools package from repo.sawtooth.me, but maybe can be a solution to set this package on rest-api, subscriber and processor.
Note that PR #32 updates Sawtooth to 1.2 and also removes the old version restriction on package python3-grpcio-tools from version 1.1.3-1 to now allow any version.
