HuggingFace Server

Thanks to our collaboration with the HuggingFace team you can now easily deploy your models from the HuggingFace Hub with Seldon Core.

We also support the high performance optimizations provided by the Transformer Optimum framework.

Pipeline parameters

The parameters that are available for you to configure include:

Name	Description
task	The transformer pipeline task
pretrained_model	The name of the pretrained model in the Hub
pretrained_tokenizer	Transformer name in Hub if different to the one provided with model
optimum_model	Boolean to enable loading model with Optimum framework

Simple Example

You can deploy a HuggingFace model by providing parameters to your pipeline.

apiVersion: machinelearning.seldon.io/v1alpha2
kind: SeldonDeployment
metadata:
  name: gpt2-model
spec:
  protocol: v2
  predictors:
  - graph:
      name: transformer
      implementation: HUGGINGFACE_SERVER
      parameters:
      - name: task
        type: STRING
        value: text-generation
      - name: pretrained_model
        type: STRING
        value: distilgpt2
    name: default
    replicas: 1

Quantized & Optimized Models with Optimum

You can deploy a HuggingFace model loaded using the Optimum library by using the optimum_model parameter.

apiVersion: machinelearning.seldon.io/v1alpha2
kind: SeldonDeployment
metadata:
  name: gpt2-model
spec:
  protocol: v2
  predictors:
  - graph:
      name: transformer
      implementation: HUGGINGFACE_SERVER
      parameters:
      - name: task
        type: STRING
        value: text-generation
      - name: pretrained_model
        type: STRING
        value: distilgpt2
      - name: optimum_model
        type: BOOL
        value: true
    name: default
    replicas: 1

Custom Model Example

You can deploy a custom HuggingFace model by providing the location of the model artefacts using the modelUri field.

apiVersion: machinelearning.seldon.io/v1alpha2
kind: SeldonDeployment
metadata:
  name: custom-tiny-stories-model
spec:
  protocol: v2
  predictors:
  - graph:
      name: transformer
      implementation: HUGGINGFACE_SERVER
      modelUri: gs://seldon-models/v1.18.0/huggingface/text-gen-custom-tiny-stories
      parameters:
      - name: task
        type: STRING
        value: text-generation
    name: default
    replicas: 1
