+unstructured[all-docs] # Includes pypdf, python-docx, openpyxl, Pillow, pytesseract, lxml, etc.
+# pdf2image # often a dependency for unstructured PDF processing with images

-unstructured # Base library for UnstructuredFileLoader
-pypdf # Dependency for UnstructuredFileLoader for PDFs
-python-docx # Dependency for UnstructuredFileLoader for DOCX
-openpyxl # Dependency for UnstructuredFileLoader for XLSX
-xlrd # Dependency for UnstructuredFileLoader for older XLS files
-python-pptx # Dependency for UnstructuredFileLoader for PPTX
-beautifulsoup4 # Dependency for UnstructuredFileLoader for HTML
-lxml # Often a useful parser for unstructured
-markdown # For .md file processing by unstructured
-pymagic # For file type detection, unstructured might need it
-libmagic # System dependency for pymagic, often needs manual install (e.g., brew install libmagic / sudo apt-get install libmagic1) - for HF Spaces, usually pre-installed or handled by base image.
-
-# Optional, for advanced PDF table/layout analysis with unstructured (strategy="hi_res"):
-# detectron2 # This has more complex installation steps (PyTorch, torchvision, etc.)
-#             # Refer to official detectron2 installation guide. May not be straightforward on Hugging Face free tier.
-# Pillow # Usually a dependency of detectron2 or unstructured itself
-
-# Other potential dependencies for unstructured depending on file types:
-# tabulate # For markdown table conversion
-# pandas # Often used by excel/csv loaders
-
-# Note on libmagic:
-# For Hugging Face Spaces, common system libraries are often available.
-# If you encounter issues with 'libmagic' locally, install it using your system's package manager:
-# macOS: brew install libmagic
-# Debian/Ubuntu: sudo apt-get install libmagic1
-# Windows: Requires a different approach, often involving manual DLL placement or using a pre-compiled package.
