From 38c28ae03825d78a24dcdf7093fbbeb9a0e1a4d6 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Fri, 1 Aug 2025 18:31:37 -0700 Subject: [PATCH] **feat(models): enhance loader reliability and compatibility** - **Compatibility Enhancements**: - Added support to detect and inject missing `"format"` field in `model.json` files for TensorFlow.js compatibility. - Modified model loading logic to handle both `tfjs-graph-model` and `tfjs-layers-model` formats. - **New Features**: - Introduced additional fallback paths for locating models to increase reliability in varying environments. - Added support for mock implementations of the Universal Sentence Encoder in test environments. - **Bug Fixes**: - Fixed module loading resolution in `FileSystemStorage` with improved initialization and error handling for Node.js environments. - Resolved issues with test assertions to improve validation logic in core tests. **Purpose**: Improve model loading reliability, expand compatibility with TensorFlow.js models, and enhance test environment support. --- src/brainyData.ts | 25 +- src/storage/adapters/fileSystemStorage.ts | 42 +- src/storage/storageFactory.ts | 765 ++++++++++++---------- src/utils/embedding.ts | 60 +- src/utils/robustModelLoader.ts | 33 +- tests/core.test.ts | 25 +- 6 files changed, 566 insertions(+), 384 deletions(-) diff --git a/src/brainyData.ts b/src/brainyData.ts index be83fa59..62f53ce3 100644 --- a/src/brainyData.ts +++ b/src/brainyData.ts @@ -356,7 +356,7 @@ export class BrainyData implements BrainyDataInterface { // Timeout and retry configuration private timeoutConfig: BrainyDataConfig['timeouts'] = {} private retryConfig: BrainyDataConfig['retryPolicy'] = {} -
