Inferoxy is a service for quick deploying and using dockerized Computer Vision models. It's a core of EORA's Computer Vision platform Vision Hub that runs on top of AWS EKS.
You should use it if:
- You want to simplify deploying Computer Vision models with an appropriate Data Science stack to production: all you need to do is to build a Docker image with your model including any pre- and post-processing steps and push it into an accessible registry
- You have only one machine or cluster for inference (CPU/GPU)
- You want automatic batching for multi-GPU/multi-node setup
- Model versioning
Inferoxy is built using message broker pattern.
- Roughly speaking, it accepts user requests through different interfaces which we call "bridges". Multiple bridges can run simultaneously. Current supported bridges are REST API, gRPC and ZeroMQ
- The requests are carefully split into batches and processed on a single multi-GPU machine or a multi-node cluster
- The models to be deployed are managed through Model Manager that communicates with Redis to store/retrieve models information such as Docker image URL, maximum batch size value, etc.
One of the core Inferoxy's features is the batching mechanism.
- For batch processing it's taken into consideration that different models can utilize different batch sizes and that some models can process a series of batches from a specific user, e.g. for video processing tasks. The latter models are called "stateful" models while models which don't depend on user state are called "stateless"
- Multiple copies of the same model can run on different machines while only one copy can run on the same GPU device. So, to increase models efficiency it's recommended to set batch size for models to be as high as possible
- A user of the stateful model reserves the whole copy of the model and releases it when his task is finished.
- Users of the stateless models can use the same copy of the model simultaneously
- Numpy tensors of RGB images with metadata are all going through ZeroMQ to the models and the results are also read from ZeroMQ socket
The cluster management consists of keeping track of the running copies of the models, load analysis, health checking and alerting.
You can run Inferoxy locally on a single machine or k8s cluster. To run Inferoxy, you should have a minimum of 4GB RAM and CPU or GPU device depending on your speed/cost trade-off.
To run locally you should use Inferoxy Docker image. The last version you can find here.
docker pull public.registry.visionhub.ru/inferoxy:v1.0.4After image is pulled we need to make basic configuration using .env file
# .env
CLOUD_CLIENT=docker
TASK_MANAGER_DOCKER_CONFIG_NETWORK=inferoxy
TASK_MANAGER_DOCKER_CONFIG_REGISTRY=
TASK_MANAGER_DOCKER_CONFIG_LOGIN=
TASK_MANAGER_DOCKER_CONFIG_PASSWORD=
MODEL_STORAGE_DATABASE_HOST=redis
MODEL_STORAGE_DATABASE_PORT=6379
MODEL_STORAGE_DATABASE_NUMBER=0
LOGGING_LEVEL=INFOThe next step is to create inferoxy Docker network.
docker network create inferoxyNow we should run Redis in this network. Redis is needed to store information about your models.
docker run --network inferoxy --name redis redis:latest Create models.yaml file with simple set of models. You can read about models.yaml in
documentation
stub:
address: public.registry.visionhub.ru/models/stub:v5

docker run --env-file .env
