Re: [protobuf] Re: How to import protocol buffer definitions from another Python package?
Right, --proto_path should always point at the "root" of your source tree, and all imports should be fully-qualified. Probably the documentation for "import" in the language guide should include a bit more text on this, as it comes up a lot. If you file a bug I'll update it when I get time. Thanks for offering to help, BTW. Unfortunately our documentation is not in a repository that can easily be edited from the outside.

[protobuf] Re: How to import protocol buffer definitions from another Python package?
Nevermind! I fixed it... The solution was to use import "sift/sift_descriptors.proto" in filtered_descriptors.proto, and then point protoc to --proto_path=../ instead of --proto_path=../sift. Then, protoc generates python code that does the import as import sift.sift_descriptors_pb2. This isn't explained well in the documentation. How can I help write something?

Sorry, transcription error... I meant "import sift_descriptors_pb2" where I wrote "import sift_descriptors_pb2.py" both times.
