*Hi Richard and Jeff,* I hope you're both doing well.
I would like to provide an update on the gRPC-based Python client integration. I have reached the stage where the client connects and RPC calls are being made, but I am consistently receiving a server-side error when attempting sentence detection. To assist with debugging, I have pushed the *entire raw state* of my environment to my repository: *https://github.com/JOBIN-SABU/opennlp-sandbox-experiments <https://www.google.com/url?sa=E&source=gmail&q=https://github.com/JOBIN-SABU/opennlp-sandbox-experiments>* *Technical Context:* - 1. *Working Directory:* tmp-opennlp-sandbox1/opennlp-sandbox/opennlp-grpc/target/ 2. *Server Command:* java -cp "opennlp-grpc-server-2.5.8-SNAPSHOT.jar:models/:" -Dopennlp.model.dir=. org.apache.opennlp.grpc.OpenNLPService 3. *Model Location:* ./models/opennlp/tools/sentdetect/en-sent.bin 4. *The Error:* grpc._channel._InactiveRpcError: status = StatusCode.INTERNAL, details = "Could not find the given model." I suspect the issue lies in how the gRPC wrapper handles resource loading—specifically whether it expects models on the *ClassPath* or supports *Relative/Absolute File System paths* via the config file. Since I’ve experimented with both flat and nested directory hierarchies without success, I would appreciate any insight into the "expected" pathing for the Sandbox server. *Regarding GSoC 2026:* As I have been contributing to this for nearly a year, my goal remains to establish a robust bridge between OpenNLP and the Python community. I would love to formally propose this as a project for the *GSoC 2026 cycle* to move these features from the sandbox into a production-ready state. Beyond fixing the current integration, my proposal includes: - *Expanding Services:* Implementing NER (Named Entity Recognition) and Chunking as gRPC services. - *Pythonic SDK:* Developing a client library for distribution via PyPI/pip. - *Documentation:* Creating comprehensive benchmarks and "Getting Started" guides. Given my deep involvement in the current implementation, *would either of you be interested in mentoring me for this project during the upcoming GSoC cycle?* I am eager to see this through to completion for the Apache OpenNLP community.
