Frequently Asked Questions about Kaggle
What is Kaggle and what can I do there?▾
Kaggle is an online platform for data science and machine learning where you can find datasets, run code in hosted notebooks, learn with tutorials and courses, and participate in predictive modeling competitions and community discussions.
How do I create an account and start using Kaggle?▾
Sign up with an email or a Google account on the Kaggle site, then verify your account; you can immediately browse datasets, open notebooks, and join discussions or competitions.
How do Kaggle competitions work and how do I submit my solution?▾
Competitions provide a problem statement and data; you develop a model or predictions locally or in a Kaggle notebook and submit prediction files through the competition submission page, where leaderboard scoring and evaluation are automated according to the contest rules.
What are Kaggle notebooks and can I run code online?▾
Kaggle notebooks (previously Kernels) are cloud-hosted Jupyter-style environments that let you write, run, and share Python or R code directly in the browser, with access to many public datasets; execution and resource availability are subject to platform limits.
Are free compute resources like GPUs or TPUs available on Kaggle?▾
Kaggle offers free hosted compute that may include CPU and limited GPU/accelerator access for notebooks, but availability, session durations, and resource limits can vary and are controlled by platform policies.
Can I upload my own datasets or download datasets from Kaggle?▾
Yes — you can upload datasets to create public or private dataset pages and download most public datasets for local use; always check the dataset page for download instructions and any access or size restrictions.
How do dataset licenses and usage restrictions work on Kaggle?▾
Each dataset page displays its license and usage terms, and you must follow those terms when using or redistributing data; if no license is listed, treat the data as potentially restricted and contact the publisher for clarification.
What learning resources does Kaggle provide for beginners?▾
Kaggle offers free short courses, tutorials, example notebooks, and community forums covering topics like Python, machine learning, and data visualization to help beginners build practical skills.
How can I collaborate with others on Kaggle projects?▾
You can share and fork notebooks, comment on and contribute to datasets, join discussion threads, and in some competitions form teams to submit combined solutions according to the event rules.
Is Kaggle free to use and are there paid or enterprise options?▾
Core Kaggle features are free for individual users, while organizations or advanced use cases may involve paid or enterprise solutions typically offered through Google Cloud or custom competition hosting services.
