3. Creating Your First Kernel
To create a new notebook:
- Click “New Notebook” to open a fresh environment.
- Familiarize yourself with the components: Code Editor, Output Area, File Browser, and Settings Panel.
4. Adding Data to Your Kernel
You can add data in three ways:
- From Kaggle Datasets: Click “Add Input,” search for a dataset, and click “Add.”
- From a Competition: Data is automatically available if you created a kernel from a competition.
- Upload Your Own Data: Click “Add data” > “Upload” and select files from your computer (up to 20GB).
5. Writing and Running Code
To run your code:
- Type your code in a code cell.
- Press “Shift+Enter” or click the “Run” button to execute.
- Add new cells as needed.
6. Using GPU/TPU Accelerators
For resource-intensive tasks, select an accelerator in the “Settings” tab:
- None (default CPU)
- GPU (T4 x2)
- GPU P100
- TPU VM (v3-8)
7. Installing Additional Packages
To install packages:
- Use pip in your code.
- Go to “Add-ons” > “Install Dependencies” to enter the package name and version.
8. Saving and Sharing Your Work
To save and share:
- Click “Save Version” to create a snapshot.
- Choose visibility (Public/Private) and share your kernel with a link.
9. Forking and Collaborating
To collaborate:
- Find a public notebook, click “Copy & Edit” to create your version.
- Make changes and save your version.
10. Common Keyboard Shortcuts
Enhance your workflow with these shortcuts:
- Shift+Enter: Run current cell
- Ctrl+Enter: Run current cell without moving
- Alt+Enter: Run current cell and insert new cell below
- Esc+A: Insert cell above
- Esc+B: Insert cell below
- Esc+D,D: Delete current cell
- Esc+M: Change to Markdown cell
- Esc+Y: Change to Code cell
11. Troubleshooting
Common issues include:
- Kernel Timeouts: Sessions terminate after 9 hours of inactivity; save frequently.
- Memory Errors: Reduce data size or use efficient algorithms.
- Package Installation Errors: Check compatibility and try different versions.
