What is 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:
- Declare the list of dependencies (CUDA, python packages, your favorite IDE, and so on) in
- Simply run
- Develop in the isolated environment.
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, it works both for local Docker and Kubernetes clusters in the cloud.
✍️ 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?
Setup your first
envd environment in 3 minutes
- Docker (20.10.0 or above)
Install and bootstrap
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
-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
Please clone the
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 NAME JUPYTER SSH TARGET CONTEXT IMAGE GPU CUDA CUDNN STATUS CONTAINER ID envd-quick-start http://localhost:42779 envd-quick-start.envd /home/gaocegege/code/envd-quick-start envd-quick-start:dev false <none> <none> Up 54 seconds bd3f6a729e94
