Has happened a couple of times on fresh installations of the toolchains, I am not able to build with NANOPB enabled due to the provided python executable not having the protobuf or grpcio_tools packages installed. Currently using Windows.

I have to manually execute pip for the packaged python version (not the system one) using c:\ncs\toolchains\v2.1.1\opt\bin\python.exe -m pip install protobuf grpcio_tools
Not sure if this is expected or not. Installing it to the system python version does not work either as the toolchain's python does not look here.
Just wanting to know if this a "bug" or if it's intended.
Thanks
