Best Practices

Search Strategy

1. Start broad - Use general keywords first
2. Refine iteratively - Add filters based on results
3. Check multiple sources - Different repositories have different strengths
4. Review metadata - Check size, format, license before downloading

Download Management

1. Check size first - Use search to see dataset size
2. Preview before download - When possible, preview samples
3. Organize by source - Keep repository structure clear
4. Track downloads - Use list command to manage local datasets

Data Quality

1. Always preview - Check data before using
2. Generate data cards - Document all datasets
3. Validate data - Check for missing values, outliers
4. Keep metadata - Save original descriptions and licenses

Storage

1. Use version control - Track dataset versions
2. Compress when possible - Use Parquet or HDF5 for large datasets
3. Clean regularly - Remove unused datasets
4. Backup important data - Keep copies of critical datasets

Troubleshooting

Installation Issues

"Missing required dependency"

# Install all dependencies
pip install kaggle datasets pandas huggingface-hub requests beautifulsoup4

# Or use virtual environment
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

"Kaggle API credentials not found"

1. Go to https://www.kaggle.com/settings
2. Click "Create New API Token"
3. Save kaggle.json to:
   • Linux/Mac: ~/.kaggle/
   • Windows: %USERPROFILE%\.kaggle\
4. Set permissions: chmod 600 ~/.kaggle/kaggle.json

"Hugging Face authentication required"

# Login to Hugging Face
huggingface-cli login

# Or set token
export HF_TOKEN="your_token_here"

Search Issues

"No results found"

• Try broader search terms
• Remove restrictive filters
• Check spelling
• Try different repository

"Search timeout"

• Check internet connection
• Repository may be down temporarily
• Try again in a few minutes

Download Issues

"Download failed"

• Check internet connection
• Verify dataset still exists
• Check available disk space
• Try downloading specific files

"Permission denied"

• Some datasets require accepting terms
• May need API credentials
• Check dataset license

"Out of memory"

• Use streaming for large datasets
• Download in chunks
• Use Parquet instead of CSV

Preview Issues

"Cannot load dataset"

• Check file format
• Verify file is not corrupted
• Try specifying encoding: --encoding utf-8

"Preview too slow"

• Use smaller sample size
• Preview first N rows only
• Use format-specific tools
