Troubleshooting

Files not appearing after adding from Flow

• In Jupyter, go to File → Hub Control Panel

• Click "Stop My Server"

• Click "Start My Server"

• Your files will now appear in the flow-data/ folder

• Check that the data files show as "added to notebooks" in Flow when they're selected

Package installation fails

• Check for typos in the package name
• Try upgrading pip: !pip install --upgrade pip
• Some packages may require system dependencies not available in the notebook environment
• Remember to add a '!' before pip to run a shell command, rather than just executing a notebook cell

Performance issues

• Close unused notebooks to free memory
• Restart the kernel (Kernel → Restart)
• Consider working with data subsets if your datasets are very large

Can't access my notebook

• Sometimes cookies retained on your computer can interfere with the authentication - make sure you hard refresh your browser (Cmd-Shift-R on Mac, Ctrl-Shift-R on Windows)
