        # Cog: Containers for machine learning

Cog is an open-source tool that lets you package machine learning models in a standard, production-ready container.

You can deploy your packaged model to your own infrastructure, or to [Replicate](https://replicate.com/).

## Highlights

- 📦 **Docker containers without the pain.** Writing your own `Dockerfile` can be a bewildering process. With Cog, you define your environment with a [simple configuration file](#how-it-works) and it generates a Docker image with all the best practices: Nvidia base images, efficient caching of dependencies, installing specific Python versions, sensible environment variable defaults, and so on.

- 🤬️ **No more CUDA hell.** Cog knows which CUDA/cuDNN/PyTorch/Tensorflow/Python combos are compatible and will set it all up correctly for you.

- ✅ **Define the inputs and outputs for your model with standard Python.** Then, Cog generates an OpenAPI schema and validates the inputs and outputs with Pydantic.

- 🎁 **Automatic HTTP prediction server**: Your model's types are used to dynamically generate a RESTful HTTP API using [FastAPI](https://fastapi.tiangolo.com/).

- 🥞 **Automatic queue worker.** Long-running deep learning models or batch processing is best architected with a queue. Cog models do this out of the box. Redis is currently supported, with more in the pipeline.

- ☁️ **Cloud storage.** Files can be read and written directly to Amazon S3 and Google Cloud Storage. (Coming soon.)

- 🚀 **Ready for production.** Deploy your model anywhere that Docker images run. Your own infrastructure, or [Replicate](https://replicate.com).

## How it works

Define the Docker environment your model runs in with `cog.yaml`:

```yaml

build:

  gpu: true

  system_packages:

    - "libgl1-mesa-glx"

    - "libglib2.0-0"

  python_version: "3.11"

  python_packages:

    - "torch==1.8.1"

predict: "predict.py:Predictor"

```

Define how predictions are run on your model with `predict.py`:

```python

from cog import BasePredictor, Input, Path

import torch

class Predictor(BasePredictor):

    def setup(self):

        """Load the model into memory to make running multiple predictions efficient"""

        self.model = torch.load("./weights.pth")

    # The arguments and types the model takes as input

    def predict(self,

          image: Path = Input(description="Grayscale input image")

    ) -> Path:

        """Run a single prediction on the model"""

        processed_image = preprocess(image)

        output = self.model(processed_image)

        return postprocess(output)

```

Now, you can run predictions on this model:

```console

$ cog predict -i [email protected]

--> Building Docker image...

--> Running Prediction...

--> Output written to output.jpg

```

Or, build a Docker image for deployment:

```console

$ cog build -t my-colorization-model

--> Building Docker image...

--> Built my-colorization-model:latest

$ docker run -d -p 5000:5000 --gpus all my-colorization-model

$ curl http://localhost:5000/predictions -X POST \

    -H 'Content-Type: application/json' \

    -d '{"input": {"image": "https://.../input.jpg"}}'

```

## Why are we building this?

It's really hard for researchers to ship machine learning models to production.

Part of the solution is Docker, but it is so complex to get it to work: Dockerfiles, pre-/post-processing, Flask servers, CUDA versions. More often than not the researcher has to sit down with an engineer to get the damn thing deployed.

[Andreas](https://github.com/andreasjansson) and [Ben](https://github.com/bfirsh) created Cog. Andreas used to work at Spotify, where he built tools for building and deploying ML models with Docker. Ben worked at Docker, where he created [Docker Compose](https://github.com/docker/compose).

We realized that, in addition to Spotify, other companies were also using Docker to build and deploy machine learning models. [Uber](https://eng.uber.com/michelangelo-pyml/) and others have built similar systems. So, we're making an open source version so other people can do this too.

Hit us up if you're interested in using it or want to collaborate with us. [We're on Discord](https://discord.gg/replicate) or email us at [[email protected]](mailto:[email protected]).

## Prerequisites

- **macOS, Linux or Windows 11**. Cog works on macOS, Linux and Windows 11 with [WSL 2](docs/wsl2/wsl2.md)

- **Docker**. Cog uses Docker to create a container for your model. You'll need to [install Docker](https://docs.docker.com/get-docker/) before you can run Cog. If you install Docker Engine instead of Docker Desktop, you will need to [install Buildx](https://docs.docker.com/build/architecture/#buildx) as well.

## Install

If you're using macOS, you can install Cog using Homebrew:

```console

brew install cog

```

You can also download and install the latest release of Cog

directly from GitHub by running the following commands in a terminal:

```console

sudo curl -o /usr/local/bin/cog -L "https://github.com/replicate/cog/releases/latest/download/cog_$(uname -s)_$(uname -m)"

sudo chmod +x /usr/local/bin/cog

```

Alternatively, you can build Cog from source and install it with these commands:

```console

make

sudo make install

```

## Upgrade

If you previously installed Cog from a GitHub Releases URL, you can upgrade to the latest version by running the same commands you used to install it:

```console

sudo curl -o /usr/local/bin/cog -L "https://github.com/replicate/cog/releases/latest/download/cog_$(uname -s)_$(uname -m)"

sudo chmod +x /usr/local/bin/cog

```

If you're using macOS and you previously installed Cog with Homebrew, run the following:

```console

brew upgrade cog

```
