Top 23 Python Data Analysis Projects

  • scikit-learn

    scikit-learn: machine learning in Python

    Project mention: Polars | | 2024-01-08

    sklearn is adding support through the dataframe interchange protocol ( scipy, as far as I know, doesn't explicitly support dataframes (it just happens to work when you wrap a Series in `np.array` or `np.asarray`). I don't know about PyTorch but in general you can convert to numpy.

  • Pandas

    Flexible and powerful data analysis / manipulation library for Python, providing labeled data structures similar to R data.frame objects, statistical functions, and much more

    Project mention: Help Us Build Our Roadmap – Pydantic | | 2024-02-19

    there is pull request to integrate in both pydantic extra types and into pandas cose [1]

  • gradio

    Build and share delightful machine learning apps, all in Python. 🌟 Star to support our work!

    Project mention: Show HN: Dropbase – Build internal web apps with just Python | | 2023-12-05

    There's also that library all the AI models started using that gives you a public URL to share. After researching it: is the link.

    It's used specifically for making simple UIs for machine learning apps. But I guess technically you could use it for anything.

  • best-of-ml-python

  • airbyte

    The leading data integration platform for ETL / ELT data pipelines from APIs, databases & files to data warehouses, data lakes & data lakehouses. Both self-hosted and Cloud-hosted.

    Project mention: Launch HN: Bracket (YC W22) – Two-Way Sync Between Salesforce and Postgres | | 2023-12-12

    I'l also give a shout-out to Airbyte (, with which I've had some limited success with integrating Salesforce to a local database. The particular pull for Airbyte is that we can self-host the open source version, rather than pay Fivetran a significant sum to do this for us.

    It's an immature tool, so I don't yet know that I can claim we've spent _less_ than Fivetran on the additional engineering and ops time, but it feels like it has potential to do so once stabilized.

  • ydata-profiling

    A Python Package to Tackle the Curse of Imbalanced Datasets in Machine Learning

    Project mention: What’s your approach to highly imbalanced data sets? | /r/datascience | 2023-05-26

    There's a pletora of undersampling and oversampling models you can try out. To avoid removing information form the dataset, you can focus on oversampling techniques. You can try imbalanced-learn or smote-variants. Given enough data, using fully synthetic data is also an option, you can check ydata-synthetic for it. Let us know how it turned out!
