Study Notes

Accessing Google Colab

Go to Google Colab via the link: https://colab.research.google.com/.
Sign in to access the platform.
Click on the "NEW NOTEBOOK" button to create a new Colab notebook.
Upload local notebooks using the upload button; also import from Google Drive or GitHub (authentication required).
Rename notebooks by clicking on the notebook name, typically named according to the project.

Google Colab Runtimes

Colab allows selection of different runtimes, such as CPU, GPU, or TPU.
Change runtime by navigating to the 'Runtime' menu and selecting 'Change Runtime Type'.
Recommended to shut down notebooks after use to conserve resources for other users.

Terminal Commands in Colab

Use the Colab cell for running terminal commands similar to a regular terminal.
Popular Python libraries (Pandas, NumPy, scikit-learn) come pre-installed.
To install other Python libraries, use the command: !pip install library_name.
Other commands like !ls and !pwd can also be executed to list files or display the working directory.

Importing Datasets

Essential for data scientists: import datasets into Colab as the first step in data analysis.
Google Colab is a cloud-based Jupyter notebook environment allowing machine learning and deep learning tasks.
Accessible irrespective of local computer configuration; a Google account and web browser are enough.
Free access to powerful GPUs (like Tesla K80) and TPUs enhances computational tasks.

Understanding Colab Notebooks

Notebooks in Google Colab provide a web-based platform for coding and executing code.
Allows real-time code execution with output display for easier iteration and visualization.
Supports markdown for formatted text, equations, and images, facilitating note-taking and collaboration.

Key Features of Google Colab

Free Hardware Access: Provides GPUs and TPUs for improved training speeds.
Web-Based Interface: User-friendly, no local software installation needed.
Collaboration: Multiple users can work on the same notebook, integrating seamlessly with Google Drive and GitHub.
Data Upload: Basic upload of datasets directly, revamping smaller files; alternatively, integrate with Google Drive for larger datasets.

Notebooks are stored on Google Drive, auto-saved periodically to prevent data loss.
Options to export notebooks into *.py and *.ipynb formats for local storage.
Sharing notebooks is simplified through the “Share” button, allowing for shareable links or invites via email, mimicking Google Docs sharing functionality.
