Notes

All Datasets Downloaded: All 10 labs now have their datasets ready
Folder Structure: Labs renamed to lab_01_*, lab_02_*, etc. for better organization
Storage Used: ~24.5 GB total across all labs
Ready to Use: All labs can now be run without additional downloads
Kaggle API: Was used for downloading datasets (credentials at ~/.kaggle/kaggle.json)

Troubleshooting

Issue: Need to re-download a dataset

# Remove the specific lab's data directory
rm -rf lab_XX_*/data/*

# Run the interactive download script
./download_datasets_interactive.sh

Issue: Check dataset integrity

# Verify all datasets are present
for lab in lab_*/data; do
    echo "$(dirname $lab): $(du -sh $lab 2>/dev/null | cut -f1)"
done

Issue: Running out of space

# Current usage: ~24.5 GB
# Consider removing optional Lab 1 dataset (689 MB) if needed
rm -rf lab_01_image_processing/data/*

Verification

All datasets verified and ready:

# Current status (as of last check):
lab_01_image_processing: 689M [OK]
lab_02_cifar10_classifiers: 340M [OK]
