🚀

New Release! Git-backed Machine Learning Model Registry for all your model management needs.

Continuous Machine Learning (CML) is CI/CD for Machine Learning Projects

Get StartedDownload
We’re on GitHub

GitFlow for data science

Use GitLab, GitHub, or Bitbucket to manage ML experiments, track who trained ML models or modified data and when. Codify data and models with DVC instead of pushing to your Git repo.

Auto reports for ML experiments

Auto-generate reports with metrics and plots in each Git Pull Request. Rigorous engineering practices help your team make informed, data-driven decisions.

No additional services

Build your own ML platform using just GitHub or GitLab and your favorite cloud services: AWS, Azure, GCP, or Kubernetes. No databases, services or complex setup needed.

CML Use Cases

The simplest case of using CML, and a clear way for any user to get started, is to generate a simple report. Add the following .yaml to your project repository and commit to get started

.gitlab-ci.yml

train-and-report:
image: iterativeai/cml:0-dvc2-base1
script:
- pip install -r requirements.txt
- python train.py # generate plot.png
# Create CML report
- cat metrics.txt >> report.md
- echo '![](./plot.png "Confusion Matrix")' >> report.md
- cml comment create report.md
