What are the most popular data science and machine learning platforms in 2026?

As of my last knowledge update in October 2023, I can't provide specific information about the most popular data science and machine learning platforms in 2026. However, I can mention some platforms that were gaining traction and popularity up to 2023, which may continue to be relevant in 2026. These include:

1. **TensorFlow**: An open-source library developed by Google for numerical computation and machine learning, widely used for deep learning applications.

2. **PyTorch**: Developed by Facebook, PyTorch is another open-source machine learning library that has gained popularity for its dynamic computation graph and ease of use, especially in research.

3. **Scikit-learn**: A popular library for classical machine learning algorithms in Python, known for its simplicity and efficiency.

4. **Keras**: A high-level neural networks API that runs on top of TensorFlow, making it easier to build and train deep learning models.

5. **Apache Spark**: A unified analytics engine for big data processing, with built-in modules for streaming, SQL, machine learning, and graph processing.

6. **H2O.ai**: An open-source platform that provides tools for building machine learning models, known for its AutoML capabilities.

7. **Microsoft Azure Machine Learning**: A cloud-based service that provides a range of tools for building, training, and deploying machine learning models.

8. **Amazon SageMaker**: A fully managed service that provides tools to build, train, and deploy machine learning models at scale.

9. **Google Cloud AI Platform**: A suite of tools and services for building and deploying machine learning models on Google Cloud.

10. **DataRobot**: An automated machine learning platform that helps users build and deploy predictive models without extensive coding.

11. **RapidMiner**: A data science platform that provides an integrated environment for data preparation, machine learning, and model deployment.

12. **Tableau**: While primarily a data visualization tool, Tableau has been integrating more machine learning capabilities, making it popular for data analysis.

To get the most accurate and up-to-date information about the most popular platforms in 2026, I recommend checking industry reports, surveys, and technology news sources closer to that time.
