pdf files indexing not working

[PatJack01]

Hi,

During indexing, I'm getting following message for each pdf file :

WARNING - [backend.semantic_search:run_indexing_task:307] - Could not load file "filename" with UnstructuredLoader.

ModuleNotFoundError: No module named 'fusion_utils'

I'm using out of the box settings
Thanks for help

Thanks for reporting!

This was a classic dependency issue with unstructured and onnxruntime when bundled via PyInstaller, specifically ModuleNotFoundError: fusion_utils. Fixed in v1.0.14.

✅ Use the main branch or grab the binary from Releases when available.
⚠️ PFS is still in an early version and needs more tests, feedback is welcome!

Enjoy!
