Model Serving as Code for PyTorch

Getting Started

TorchLego is a server for running inference on PyTorch models. It is inspired by the concept of X-as-Code e.g. Infrastructure-as-Code, Security-as-Code, etc. With TorchLego, one can define the preprocess, postprocess and PyTorch TorchScript module location as a config for execution.

Usage

  • Create a TorchLego model configuration file models.yaml in YAML format. You can refer to following YAML:
models:
  - name: torchvision-resnet50 <- unique name/slug for the model
    download: http://download-link <- module download link
    gpu: false
    stages:
      input: file <- support for file upload as input while running inference
      # default pytorch transforms for preprocessing the input
      preprocess:
        default: image_classification <- default torchvision transforms for preprocessing
  - name: custom-resnet50
    download: http://download-link <- module download link
    gpu: false
    stages:
      input: file
      # custom pytorch transforms for preprocessing the input
      preprocess:
        resize: 299
        center_crop: 299
        to_tensor: true
        normalize:
          mean: [0.485, 0.456, 0.406]
          std: [0.229, 0.224, 0.225]
        unsqueeze: 0
  • Run the following command to run an example configuration. Note, TorchLego picks up config files from model-config folder from the root directory.
docker run --rm --net=host -v ${PWD}/examples:/model-config prabhuomkar/torchlego:latest
