            # Training step
            loss = train_step(model, batch)
            # Update progress bar
            tqdm.write(f"Loss: {loss:.4f}")

Experiment Management​

  1. Experiment Tracking

    from gitcode.tracking import track_experiment

    @track_experiment
    def run_experiment(params):
        # Experiment configuration
        config = {
            "model": "resnet50",
            "params": params
        }
        
        # Run experiment
        results = train_model(config)
        
        return results

  2. Result Visualization

    # Training curve
    plt.figure(figsize=(12, 6))
    plt.plot(history['loss'], label='train')
    plt.plot(history['val_loss'], label='validation')
    plt.legend()
    plt.title('Training History')

Collaboration Features​

      comments: true

Extension Features​

Plugin System​

  1. Extension Installation

    # Install extension
    !jupyter nbextension install extension-name

    # Enable extension
    !jupyter nbextension enable extension-name

  2. Custom Extensions

    // Custom toolbar button
    define([
        'base/js/namespace'
    ], function(Jupyter) {
        function load_ipython_extension() {
            // Add custom button
            Jupyter.toolbar.add_buttons_group([
                Jupyter.keyboard_manager.actions.register({
                    'help': 'Run all cells',
                    'icon': 'fa-play',
                    'handler': run_all
                }, 'run-all', 'Custom')
            ])
        }
        return {
            load_ipython_extension: load_ipython_extension
        };
    });

            "disk_usage": get_disk_usage()
        }
        return metrics

  2. Performance Analysis

    # Code performance analysis
    %load_ext line_profiler
    %lprun -f function_name function_name(args)

    # Memory analysis
    %load_ext memory_profiler
    %memit function_name(args)

Usage Tips​

Development Tips​

Code Organization: Split code into small parts for easier understanding, manage code with version control, add comments to explain code functions, and save work regularly.

Performance Optimization: Choose appropriate data structures, optimize computationally intensive operations, use caching effectively, and release unnecessary resources promptly.

Collaboration Tips​

Team Collaboration: Write clear code explanations, maintain consistent code style, communicate and provide feedback promptly, and update code versions regularly.

Secure Usage: Protect sensitive information, control access permissions, back up important data regularly, and follow platform usage guidelines.

Summary​

Notebook is a powerful online programming environment. With Notebook, you can develop quickly (no need to install software, start coding directly), experiment efficiently (interactive programming, see results in real time), work data-driven (powerful data processing and visualization capabilities), and collaborate with teams (support for collaborative development).

Remember, Notebook makes programming simple and fun. Start with simple code, learn gradually, and you will master various AI development skills!
