No module named 'sawtooth_sdk.protobuf'

Failed to import Stream from sawtooth_sdk.messaging.stream, because submodule protobuf is missing since 1.2.4.

from sawtooth_sdk.messaging.stream import Stream

 Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/sawtooth_sdk/messaging/stream.py", line 27, in <module>
    from sawtooth_sdk.protobuf import validator_pb2
ModuleNotFoundError: No module named 'sawtooth_sdk.protobuf'

Python 3.8
sawtooth-sdk 1.2.4
ubuntu 20.04

The problem seems to be in the provided wheel package.

Workaround
A workaround is to add the option "--no-binary sawtooth-sdk" to pip install command.
pip3 install --no-binary sawtooth-sdk sawtooth-sdk
This will work in your CLI, but not in a pipeline, because of get_version binary not found.

Workaround 2
This will work for pipelines.

python3 -m pip install grpcio-tools
git clone --depth 1 --branch v1.2.4 https://github.com/hyperledger/sawtooth-sdk-python.git
python3 sawtooth-sdk-python/bin/protogen
python3 -m pip install sawtooth-sdk-python/
rm -rf sawtooth-sdk-python

I had the same issue, workaround 2 by @m-unkel worked for me. But is this issue still pending ? I wonder how other people are working with the sdk.
