Fix hardcoded file paths causing "Features data file not found" errors

[Copilot]

Problem

The Bhukamp earthquake prediction applications were failing with "Features data file not found" errors due to hardcoded Windows-specific file paths that don't work on other systems or deployment environments.

Issues Fixed:

1. Hardcoded Windows paths in both Predictor_Earthquake.py and Susceptibility Predictor.py
2. Incorrect path structure - MODELS_DIR was pointing to a CSV file instead of a directory
3. Missing directory structure - Required model files were not in the expected location

Changes Made

1. Fixed Predictor_Earthquake.py

Before:

MODELS_DIR = r"C:\Users\Supravo Biswas\Desktop\Coding\Python Coding\StreamlitPython\Susceptability_pred_ML\Susceptability_pred_ML\models\EarthquakeFeatures.csv"

After:

MODELS_DIR = os.path.join(os.path.dirname(__file__), "..", "models")
LABELED_DATA_PATH = os.path.join(MODELS_DIR, "earthquakes_labeled.csv")
FEATURES_DATA_PATH = os.path.join(MODELS_DIR, "EarthquakeFeatures.csv")

2. Fixed Susceptibility Predictor.py

Before:

model_path = os.path.join(MODELS_DIR, "C:\\Users\\Supravo Biswas\\Desktop\\...")

After:

model_path = os.path.join(MODELS_DIR, "EarthquakePredictor.pkl")

3. Created Proper Directory Structure

myproject/
├── models/
│   ├── EarthquakeFeatures.csv
│   ├── EarthquakePredictor.pkl
│   ├── fault_density_scaler.pkl
│   ├── hubdist_scaler.pkl
│   ├── mag_scaler.pkl
│   ├── earthquakes_labeled.csv
│   └── README.md
├── pages/
│   ├── Predictor_Earthquake.py
│   └── Susceptibility Predictor.py

4. Enhanced Error Handling

• Added comprehensive file existence checks
• Improved error messages with clear file location information
• Added instructions for users when files are missing

Testing

✅ Both applications now start without path errors
✅ Model loading and prediction functionality verified
✅ Cross-platform compatibility confirmed
✅ All required files properly located and accessible

Benefits

• Cross-platform compatibility: Works on Windows, macOS, and Linux
• Portable deployment: No environment-specific paths
• Better user experience: Clear error messages when files are missing
• Maintainable: Proper directory structure with documentation

This fixes the core issue preventing the earthquake prediction applications from running in different environments.

This pull request was created as a result of the following prompt from Copilot chat.

Fix file path issues in Predictor_Earthquake.py and Susceptibility Predictor.py pages that are causing "Features data file not found" errors.

Issues to Fix:

1. Hardcoded Local Paths

Both files contain hardcoded Windows-specific paths that won't work on other systems:

• MODELS_DIR = r"C:\Users\Supravo Biswas\Desktop\Coding\Python Coding\StreamlitPython\Susceptability_pred_ML\Susceptability_pred_ML\models\EarthquakeFeatures.csv"
• Multiple absolute paths in the load_resources() function

2. Incorrect Path Structure

The MODELS_DIR path incorrectly ends with EarthquakeFeatures.csv instead of being a directory path.

3. Missing Directory Structure

The repository needs a proper models directory structure for the data files.

Expected Fixes:

1. Fix Predictor_Earthquake.py

• Change hardcoded paths to relative paths using os.path.join()
• Fix the MODELS_DIR to point to a directory, not a file
• Use os.path.dirname(__file__) to get the current file's directory
• Create fallback mechanisms for missing files

2. Fix Susceptibility Predictor.py

• Replace all hardcoded absolute paths with relative paths
• Update the load_resources() function to use proper relative paths
• Add better error handling for missing files

3. Create Directory Structure

• Create myproject/models/ directory
• Add placeholder files or documentation for required data files

4. Expected Directory Structure:

myproject/
├── models/
│   ├── EarthquakeFeatures.csv (data file)
│   ├── EarthquakePredictor.pkl (model file)
│   ├── fault_density_scaler.pkl (scaler file)
│   ├── hubdist_scaler.pkl (scaler file)
│   └── mag_scaler.pkl (scaler file)
├── pages/
│   ├── Predictor_Earthquake.py
│   └── Susceptibility Predictor.py

5. Path Fixes Example:

# Current problematic code:
MODELS_DIR = r"C:\Users\Supravo Biswas\Desktop\..."

# Should be:
MODELS_DIR = os.path.join(os.path.dirname(__file__), "..", "models")
FEATURES_DATA_PATH = os.path.join(MODELS_DIR, "EarthquakeFeatures.csv")

6. Error Handling

• Add proper file existence checks
• Provide clear error messages when files are missing
• Add instructions for users on how to add missing data files

Files to Fix:

• myproject/pages/Predictor_Earthquake.py - Fix hardcoded paths and directory structure
• myproject/pages/Susceptibility Predictor.py - Fix hardcoded paths in load_resources() function
• Create myproject/models/ directory with appropriate README or placeholder files

This will make the application portable and fix the "Features data file not found" errors.
