+# Final Fix for ModuleNotFoundError on Hugging Face Spaces
+
+## Problem Summary
+The persistent `ModuleNotFoundError: No module named 'controller'` error was occurring because:
+1. Gunicorn was trying to import modules before the Python environment was properly configured
+2. There was no verification of imports before starting the application
+3. The Python path wasn't being set correctly in the container environment
+
+## Solution Implemented
+
+### 1. Dedicated Startup Script (`startup.sh`)
+Created a robust startup script that:
+- Explicitly sets `PYTHONPATH` to include all necessary directories
+- Determines the correct Python command to use (`python3` or `python`)
+- Verifies that critical imports work before starting the application
+- Provides clear error messages if imports fail
+- Only proceeds to start gunicorn if all imports succeed
+
+### 2. Updated Dockerfile
+- Ensures the startup script is properly copied and made executable
+- Adds debugging output to verify the script exists
+- Uses the startup script as the entry point
+
+### 3. Proper Error Handling
+The startup script follows this sequence:
+1. Set up environment variables
+2. Determine which Python command to use
+3. Test Python path setup
+4. Test controller module import
+5. Test specific controller import (pix2text_controller)
+6. Start gunicorn only if all tests pass
+
+## Why This Fix Works
+
+### Early Import Verification
+By testing imports before starting gunicorn, we catch import issues early with clear diagnostics rather than letting them cause cryptic errors during worker initialization.
+
+### Explicit Path Management
+The script explicitly manages the Python path, ensuring that all necessary directories are included before any imports are attempted.
+
+### Robust Command Detection
+The script determines which Python command is available in the environment, making it compatible with different container setups.
+
+## Expected Outcomes
+
+### Success Case (in Hugging Face logs):
+```
+=== STARTUP.SH EXECUTING ===
+Using python3
+=== TESTING PYTHON PATH SETUP ===
+✅ Python path setup successful
+=== TESTING CONTROLLER IMPORT ===
+✅ Controller module imported successfully
+=== TESTING PIX2TEXT CONTROLLER IMPORT ===
+✅ pix2text_controller imported successfully
+=== ALL IMPORTS SUCCESSFUL, STARTING GUNICORN ===
+```
+
+### Failure Case (in Hugging Face logs):
+```
+=== STARTUP.SH EXECUTING ===
+Using python3
+=== TESTING PYTHON PATH SETUP ===
+✅ Python path setup successful
+=== TESTING CONTROLLER IMPORT ===
+❌ Failed to import controller module
+[Detailed error information]
+```
+
+## Files Modified
+
+1. **`startup.sh`** - New startup script with import verification
+2. **`Dockerfile`** - Updated to use the startup script as entry point
+3. **No changes to `app.py`** - Keeping the original functionality
+
+This approach follows the proven pattern from the memory "Hugging Face Spaces startup script pattern" and should resolve the persistent ModuleNotFoundError.
