I investigated a bit more. `pyarrow` is built with Substrait support alright. That's how we can get an error from `pyarrow/substrait.py`. The problem is rather (as the error message says) that some package from with `substrait` (standalone!) cannot be found. The difference in our environments explains why it fails/failed for me: I used `substrait==0.12.1`; starting with `substrait==0.15`, it works. Presumably, that version starts to include the protobuf definitions (at least, under that name). The proper fix, thus, seems to be to require that version in some setup file (or test for that version in `pyarrow/substrait.py`). -- This is an automated message from the Apache Git Service.
