 Instructions:
-- Only include external packages that need to be installed via pip
+- 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., cv2 -> opencv-python, PIL -> Pillow, sklearn -> scikit-learn)
+- Examples of comprehensive dependencies:
+  * 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
-- Use the correct PyPI package names (e.g., cv2 -> opencv-python, PIL -> Pillow, sklearn -> scikit-learn)
-- Do not specify versions unless absolutely necessary for compatibility
+- 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"
