ComfyUI-Data-Analysis

Update (March 3, 2025)

Training workflow trains the FashionMNIST model from scratch with a single click of a button.

Experimental PyTorch model training has been added (documentation coming soon). No coding required—training is as simple as a single click!

Try it out:

Training: examples/fashion_mnist_train.json
Evaluation: examples/fashion_mnist_eval.json

This workflow trains a FashionMNIST model from scratch effortlessly.

Eval workflow

Note that the training feature is a proof of concept and currently supports only the dense model. Additional models may be added based on demand.

How Can We Figure Out Which MLB Player Had the Most Hits Per Year?

If you love ComfyUI, it's likely because of its incredible flexibility—allowing you to customize workflows to achieve exactly the results you want, primarily in image generation.

ComfyUI was designed to make Stable Diffusion accessible to non-engineers while offering extensive customization. However, it doesn’t natively support structured data like baseball statistics. That’s why I created this ComfyUI extension—to bridge that gap.

At the end of this page, you’ll find a tutorial on how to use this package to answer the MLB hits question.

I hope you find it useful and engaging for data exploration.

ComfyUI-Data-Analysis is an extension for ComfyUI that provides custom nodes for data analysis using Pandas, Seaborn, and Matplotlib within ComfyUI.

Originally designed for structural data analysis, this extension is for you if you:

• Want access to PyTorch's low-level methods (e.g., add, div, max, where, scatter, gather) to manipulate PyTorch tensors or extract information.
• Are comfortable with ComfyUI and want to learn foundational PyTorch methods without writing a single line of code.
• Want to analyze structural data (tabular data) using ComfyUI's node system.

Features

ComfyUI-Data-Analysis includes numerous custom nodes that wrap Pandas and PyTorch. For a complete list, see the Node Reference.

These nodes allow you to conduct complex analyses in an intuitive, graphical way. You can also combine them with other ComfyUI custom nodes to fit your workflow needs (e.g., integrating images).

Visualization & Analysis

These custom nodes enhance efficiency and usability in data exploration and visualization. Creating sample data and plotting it is incredibly simple:

Example plot

Additionally, you can analyze images generated in ComfyUI’s workflows. Below is an example of a histogram showing the red channel pixel distribution:

Installation

Note: GPU is not required to run this custom module.

Installation via ComfyUI Manager

1. Press Manager button on the top menu bar to display ComfyUI Manager Menu.
2. Click Custom Node Manager.
3. In the search field, enter Data analysis.
4. "ComfyUI-Data-Analysis" should be displayed. Select Install.
5. Restart ComfyUI.
6. Reload browser page.

Installation via git

1. Navigate to the custom_nodes directory within your ComfyUI installation.

2. Run the following command:

   git clone https://github.com/HowToSD/ComfyUI-Data-Analysis.git
   

   This will create a new subdirectory ComfyUI-Data-Analysis.

3. Rename the folder name from ComfyUI-Data-Analysis to data-analysis. Skipping this step will cause example workflows to fail, as they rely on this folder name.

4. Check if your ComfyUI environment already has required packages listed in requirements.txt. If not, install them using pip.

   pip install -r requirements.txt
   

   Refer to requirements.txt for the right versions.

5. Start ComfyUI.

Troubleshooting for installation

This custom node module requires pandas and matplotlib, which are not included in the default ComfyUI installation. If you install this module using ComfyUI Manager, these packages should be installed automatically. However, if installation fails, refer to the pandas and matplotlib documentation for manual installation.

How to Use

Refer to User's Guide or check out Node Reference

For a practical example, see the tutorial on baseball data: How to Find Out Who Had the Most Hits.

Update

Refer to the release notes. While backward-incompatible changes are minimized, some may be necessary. The release notes contain those changes so that you know what to expect before upgrading your version.
