-Instructions:
-- Include the direct packages needed for the imports
-- Include commonly used companion packages and dependencies for better functionality
-- Use correct PyPI package names (e.g., PIL -> Pillow, sklearn -> scikit-learn)
-- IMPORTANT: For diffusers, ALWAYS use: git+https://github.com/huggingface/diffusers
-- IMPORTANT: For transformers, ALWAYS use: git+https://github.com/huggingface/transformers
-- IMPORTANT: If diffusers is installed, also include transformers and sentencepiece as they usually go together
-- Examples of comprehensive dependencies:
-  * diffusers often needs: git+https://github.com/huggingface/transformers, sentencepiece, accelerate, torch, tokenizers
-  * transformers often needs: accelerate, torch, tokenizers, datasets
-  * gradio often needs: requests, Pillow for image handling
-  * pandas often needs: numpy, openpyxl for Excel files
-  * matplotlib often needs: numpy, pillow for image saving
-  * sklearn often needs: numpy, scipy, joblib
-  * streamlit often needs: pandas, numpy, requests
-  * opencv-python often needs: numpy, pillow
-  * fastapi often needs: uvicorn, pydantic
-  * torch often needs: torchvision, torchaudio (if doing computer vision/audio)
-- Include packages for common file formats if relevant (openpyxl, python-docx, PyPDF2)
-- Do not include Python built-in modules
-- Do not specify versions unless there are known compatibility issues
-- One package per line
-- If no external packages are needed, return "# No additional dependencies required"
-
-🚨 CRITICAL OUTPUT FORMAT:
-- Output ONLY the package names, one per line (plain text format)
-- Do NOT use markdown formatting (no ```, no bold, no headings, no lists)
-- Do NOT add any explanatory text before or after the package list
-- Do NOT wrap the output in code blocks
-- Just output raw package names as they would appear in requirements.txt
