A development environment management tool for data scientists.

Development environment for AI/ML

What is envd?

envd (ɪnˈvdɪ) is a command-line tool that helps you create the container-based development environment for AI/ML.

Development environments are full of python and system dependencies, CUDA, BASH scripts, Dockerfiles, SSH configurations, Kubernetes YAMLs, and many other clunky things that are always breaking. envd is to solve the problem:

1. Declare the list of dependencies (CUDA, python packages, your favorite IDE, and so on) in build.envd
2. Simply run envd up.
3. Develop in the isolated environment.

Why use envd?

Environments built with envd provide the following features out-of-the-box:

❤️ Knowledge reuse in your team

envd build functions can be reused. Use include function to import any git repositories. No more copy/paste Dockerfile instructions, let's reuse them.

envdlib = include("https://github.com/tensorchord/envdlib")

def build():
    base(os="ubuntu20.04", language="python")
    envdlib.tensorboard(8888)

envdlib.tensorboard is defined in github.com/tensorchord/envdlib

def tensorboard(envd_port=6006, envd_dir="/home/envd/logs",
        host_port=0, host_dir="/var/log/tensorboard"):
    """Configure TensorBoard.

    Make sure you have permission for `host_dir`

    Args:
        envd_port (Optional[int]): port used by envd container
        envd_dir (Optional[str]): log storage mount path in the envd container
        host_port (Optional[int]): port used by the host, if not specified or equals to 0,
            envd will randomly choose a free port
        host_dir (Optional[str]): log storage mount path in the host
    """
    install.python_packages(["tensorboard"])
    runtime.mount(host_path=host_dir, envd_path=envd_dir)
    runtime.daemon(
        commands=[
            [
                "tensorboard",
                "--logdir",
                "/home/envd/logs",
                "--port",
                str(envd_port),
                "--host",
                "0.0.0.0",
                ">>tensorboard.log",
                "2>&1",
            ],
        ]
    )
    runtime.expose(envd_port=envd_port, host_port=host_port, service="tensorboard")

⏱️ Builtkit native, build up to 6x faster

Buildkit supports parallel builds and software cache (e.g. pip index cache and apt cache). You can enjoy the benefits without knowledge of it.

For example, the PyPI cache is shared across builds and thus the package will be cached if it has been downloaded before.

🐍 One configuration to rule them all

Development environments are full of Dockerfiles, bash scripts, Kubernetes YAML manifests, and many other clunky files that are always breaking. You just need one configuration file build.envd[^1], it works both for local Docker and Kubernetes clusters in the cloud.

[^1]: The build language is starlark, which is a dialect of Python.

✍️ Don't sacrifice your developer experience

SSH is configured for the created environment. You can use vscode-remote, jupyter, pycharm or other IDEs that you love. Besides this, declare the IDE extensions you want, let envd take care of them.

def build():
    install.vscode_extensions([
        "ms-python.python",
    ])

☁️ No polluted environment

Are you working on multiple projects, all of which need different versions of CUDA? envd helps you create isolated and clean environments.

Who should use envd?

We’re focused on helping data scientists and teams that develop AI/ML models. And they may suffer from:

• building the development environments with Python/R/Julia, CUDA, Docker, SSH, and so on. Do you have a complicated Dockerfile or build script that sets up all your dev environments, but is always breaking?
• Updating the environment. Do you always need to ask infrastructure engineers how to add a new Python/R/Julia package in the Dockerfile?
• Managing environments and machines. Do you always forget which machines are used for the specific project, because you handle multiple projects concurrently?

Getting Started 🚀

Requirements

• Docker (20.10.0 or above)

Install and bootstrap envd

envd can be installed with pip (only support Python3). After the installation, please run envd bootstrap to bootstrap.

pip3 install --pre --upgrade envd
envd bootstrap

You can add --dockerhub-mirror or -m flag when running envd bootstrap, to configure the mirror for docker.io registry:

envd bootstrap --dockerhub-mirror https://docker.mirrors.sjtug.sjtu.edu.cn

Create an envd environment

Please clone the envd-quick-start:

git clone https://github.com/tensorchord/envd-quick-start.git

The build manifest build.envd looks like:

def build():
    base(os="ubuntu20.04", language="python3")
    # Configure the pip index if needed.
    # config.pip_index(url = "https://pypi.tuna.tsinghua.edu.cn/simple")
    install.python_packages(name = [
        "numpy",
    ])
    shell("zsh")

Note that we use Python here as an example but please check out examples for other languages such as R and Julia here.

Then please run the command below to set up a new environment:

cd envd-quick-start && envd up

Set up Jupyter notebook

Please edit the build.envd to enable jupyter notebook:

def build():
    base(os="ubuntu20.04", language="python3")
    # Configure the pip index if needed.
    # config.pip_index(url = "https://pypi.tuna.tsinghua.edu.cn/simple")
    install.python_packages(name = [
        "numpy",
    ])
    shell("zsh")
    config.jupyter()

You can get the endpoint of the running Jupyter notebook via envd envs ls.

$ envd up --detach
$ envd envs ls
