  • Options for configuration of python libraries - Stack Overflow
    2 projects | /r/learnpython | 14 May 2023
    In search for a tool that needs comparable configuration I looked into mlflow and found this. There they define a class _EnvironmentVariable and create many objects out of it, for any variable they need. The get method of this class is in principle a decorated os.getenv. Maybe that is something I can take as orientation.
  • [D] Is there a tool to keep track of my ML experiments?
    2 projects | /r/MachineLearning | 13 May 2023
    I have been using DVC and MLflow since then DVC had only data tracking and MLflow only model tracking. I can say both are awesome now and maybe the only factor I would like to mention is that IMO, MLflow is a bit harder to learn while DVC is just a git practically.

  • Integrating Hugging Face Transformers & DagsHub
    2 projects | /r/mlops | 27 Mar 2023
    While Transformers already includes integration with MLflow, users still have to provide their own MLflow server, either locally or on a Cloud provider. And that can be a bit of a pain.
  • Any MLOps platform you use?

    I have an old labmate who uses a similar setup with MLFlow and can endorse it.

    MLflow - an open-source platform for managing your ML lifecycle. What’s great is that they also support popular Python libraries like TensorFlow, PyTorch, scikit-learn, and R.
  • Selfhosted chatGPT with local contente
    3 projects | /r/selfhosted | 24 Feb 2023
    even for people who don't have an ML background there's now a lot of very fully-featured model deployment environments that allow self-hosting (kubeflow has a good self-hosting option, as do mlflow and metaflow), handle most of the complicated stuff involved in just deploying an individual model, and work pretty well off the shelf.
  • ML experiment tracking with DagsHub, MLFlow, and DVC
    4 projects | | 12 Jan 2023
    Here, we’ll implement the experimentation workflow using DagsHub, Google Colab, MLflow, and data version control (DVC). We’ll focus on how to do this without diving deep into the technicalities of building or designing a workbench from scratch. Going that route might increase the complexity involved, especially if you are in the early stages of understanding ML workflows, just working on a small project, or trying to implement a proof of concept.

  • [P] I reviewed 50+ open-source MLOps tools. Here’s the result
    3 projects | /r/MachineLearning | 29 May 2022
    Currently, you can see the integrations we support here and it includes a lot of tools in your list. I also feel I agree with your categorization (it is exactly the categorization we use in our docs pretty much). Perhaps one thing missing might be feature stores but that is a minor thing in the bigger picture.
  • [D] Feedback on a worked Continuous Deployment Example (CI/CD/CT)

    Hey everyone! At ZenML, we released today an integration that allows users to train and deploy models from pipelines in a simple way. I wanted to ask the community here whether the example we showcased makes sense in a real-world setting:
  • How we made our integration tests delightful by optimizing our GitHub Actions workflow
    3 projects | | 11 Mar 2022
    As of early March 2022 this is the new CI pipeline that we use here at ZenML and the feedback from my colleagues -- fellow engineers -- has been very positive overall. I am sure there will be tweaks, changes and refactorings in the future, but for now, this feels Zen.
  • Ask HN: Who is hiring? (March 2022)
    30 projects | | 1 Mar 2022
    ZenML is hiring for a Design Engineer.

    ZenML is an extensible, open-source MLOps framework to create production-ready machine learning pipelines. Built for data scientists, it has a simple, flexible syntax, is cloud- and tool-agnostic, and has interfaces/abstractions that are catered towards ML workflows.

    We’re looking for a Design Engineer with a multi-disciplinary skill-set who can take over the look and feel of the ZenML experience. ZenML is a tool designed for developers and we want to delight them from the moment they land on our web page, to after they start using it on their machines. We would like a consistent design experience across our many touchpoints (including the [landing page](, the [docs](, the [blog](, the [podcast](, our social media, the product itself which is a [python package]( etc).

    A lot of this job is about communicating complex ideas in a beautiful way. You could be a developer or a non-coding designer, full time or part-time, employee or freelance. We are not so picky about the exact nature of this role. If you feel like you are a visually creative designer, and are willing to get stuck in the details of technical topics like MLOps, we can’t wait to work with you!
