Once the dataset is available in the Colab notebook, you can read and process the data using Python libraries such as Pandas or NumPy.

Are there limitations on computational resources in Google Colab?

While Google Colab provides free access to computational resources, some limitations are in place to ensure fair usage and prevent abuse. The following are the resource limitations in the free tier of Google Colab:

  1. Session duration: Each Colab session has a maximum duration of 12 hours. After this period, the session is automatically terminated, and all data and outputs are lost. However, you can save your work and restart a new session.
  2. Idle timeout: If a Colab notebook remains inactive for a certain period, typically around 90 minutes, the session will be disconnected. You can reconnect and resume your work, but any unsaved data or variables will be lost.
  3. Resource limits: Colab provides a limited amount of CPU and GPU resources to each user. This ensures fair distribution and prevents excessive resource consumption by individual users.

While the limitations are in place, they generally do not hinder most machine learning tasks and are suitable for experimentation, prototyping, and small to medium-sized projects. Google Colab Pro offers extended runtime limits and higher resource allocations at a monthly subscription fee for users with more demanding requirements.

Can I install custom libraries in Google Colab?

Yes, you can install custom libraries in Google Colab. Colab provides a terminal within the notebook interface, allowing you to execute system commands and install additional Python packages or libraries using pip or conda. For example, to install a library called “mylibrary,” you may utilize the following command to run a task within a code cell.: !pip install my library. Installing custom libraries allows you to use specific tools or frameworks that are not pre-installed in the Colab environment.

What programming languages are supported in Google Colab?

Google Colab primarily supports the Python programming language. Python is widely used in the machine learning and data science communities due to its simplicity, readability, and extensive library ecosystem. Colab notebooks are created using Python kernels, which allow the execution of Python code cells. However, you can also write and execute shell commands, enabling you to leverage the power of the command-line interface within your notebooks.

How to save and download work from Google Colab?
