The error message was misleading as it appeared to be an Ollama connectivity issue, but actually occurred during faiss vector database initialization. ## 🔍 Root Cause Analysis The issue was in the faiss vector database serialization logic in `llama_stack/providers/inline/vector_io/faiss/faiss.py`: 1. **Saving**: `faiss.serialize_index()` returns binary data (uint8 numpy array) 2. **Bug**: Code incorrectly used `np.savetxt()` which converts binary to text with scientific notation (e.g., `7.300000000000000000e+01`) 3. **Loading**: `np.loadtxt(buffer, dtype=np.uint8)` failed to parse scientific notation back to uint8 4. **Result**: Server crashed during initialization before reaching Ollama connectivity check ## ✅ Solution Replaced text-based serialization with proper binary serialization: ``` **After (fixed):** ```python # Saving - proper binary format np.save(buffer, np_index, allow_pickle=False) # Loading - proper binary format self.index = faiss.deserialize_index(np.load(buffer, allow_pickle=False)) ``` ## 🧪 Testing - ✅ Binary serialization/deserialization works correctly - ✅ Backward compatible with existing functionality - ✅ No security concerns (allow_pickle=False maintained) - ✅ Resolves the specific ValueError mentioned in the issue ## 📊 Impact This fix resolves: - ValueError during server startup with Ollama templates ## 🔗 Related Issues - Closes #2519 - Affects all users of Ollama template and faiss vector_io configurations ## 📝 Files Changed - `llama_stack/providers/inline/vector_io/faiss/faiss.py` - Fixed serialization methods in `initialize()` and `_save_index()` --------- Signed-off-by: Ben Browning <bbrownin@redhat.com> Co-authored-by: Ben Browning <bbrownin@redhat.com> |

chore: enable pyupgrade fixes (#1806)
# What does this PR do? The goal of this PR is code base modernization. Schema reflection code needed a minor adjustment to handle UnionTypes and collections.abc.AsyncIterator. (Both are preferred for latest Python releases.) Note to reviewers: almost all changes here are automatically generated by pyupgrade. Some additional unused imports were cleaned up. The only change worth of note can be found under `docs/openapi_generator` and `llama_stack/strong_typing/schema.py` where reflection code was updated to deal with "newer" types.

Fix precommit check after moving to ruff (#927)
Lint check in main branch is failing. This fixes the lint check after we moved to ruff in https://github.com/meta-llama/llama-stack/pull/921. We need to move to a `ruff.toml` file as well as fixing and ignoring some additional checks. Signed-off-by: Yuan Tang <terrytangyuan@gmail.com> |

[API Updates] Model / shield / memory-bank routing + agent persistence + support for private headers (#92)
This is yet another of those large PRs (hopefully we will have less and less of them as things mature fast). This one introduces substantial improvements and some simplifications to the stack. Most important bits: * Agents reference implementation now has support for session / turn persistence. The default implementation uses sqlite but there's also support for using Redis. * We have re-architected the structure of the Stack APIs to allow for more flexible routing. The motivating use cases are: - routing model A to ollama and model B to a remote provider like Together - routing shield A to local impl while shield B to a remote provider like Bedrock - routing a vector memory bank to Weaviate while routing a keyvalue memory bank to Redis * Support for provider specific parameters to be passed from the clients. A client can pass data using `x_llamastack_provider_data` parameter which can be type-checked and provided to the Adapter implementations. |
