Wallaroo SDK Upload Tutorials: Hugging Face

How to upload different Hugging Face models to Wallaroo.

The following tutorials cover how to upload sample Hugging Face models. The complete list of supported Hugging Face pipelines are as follows.

Parameter	Description
Web Site	https://huggingface.co/models
Supported Libraries	`transformers==4.27.0` `diffusers==0.14.0` `accelerate==0.18.0` `torchvision==0.14.1` `torch==1.13.1`
Frameworks	The following Hugging Face pipelines are supported by Wallaroo. `Framework.HUGGING_FACE_FEATURE_EXTRACTION` aka `hugging-face-feature-extraction` `Framework.HUGGING_FACE_IMAGE_CLASSIFICATION` aka `hugging-face-image-classification` `Framework.HUGGING_FACE_IMAGE_SEGMENTATION` aka `hugging-face-image-segmentation` `Framework.HUGGING_FACE_IMAGE_TO_TEXT` aka `hugging-face-image-to-text` `Framework.HUGGING_FACE_OBJECT_DETECTION` aka `hugging-face-object-detection` `Framework.HUGGING_FACE_QUESTION_ANSWERING` aka `hugging-face-question-answering` `Framework.HUGGING_FACE_STABLE_DIFFUSION_TEXT_2_IMG` aka `hugging-face-stable-diffusion-text-2-img` `Framework.HUGGING_FACE_SUMMARIZATION` aka `hugging-face-summarization` `Framework.HUGGING_FACE_TEXT_CLASSIFICATION` aka `hugging-face-text-classification` `Framework.HUGGING_FACE_TRANSLATION` aka `hugging-face-translation` `Framework.HUGGING_FACE_ZERO_SHOT_CLASSIFICATION` aka `hugging-face-zero-shot-classification` `Framework.HUGGING_FACE_ZERO_SHOT_IMAGE_CLASSIFICATION` aka `hugging-face-zero-shot-image-classification` `Framework.HUGGING_FACE_ZERO_SHOT_OBJECT_DETECTION` aka `hugging-face-zero-shot-object-detection` `Framework.HUGGING_FACE_SENTIMENT_ANALYSIS` aka `hugging-face-sentiment-analysis` `Framework.HUGGING_FACE_TEXT_GENERATION` aka `hugging-face-text-generation`
Runtime	Containerized aka `tensorflow` / `mlflow`

Hugging Face Schemas

Input and output schemas for each Hugging Face pipeline are defined below. Note that adding additional inputs not specified below will raise errors, except for the following:

Framework.HUGGING-FACE-IMAGE-TO-TEXT
Framework.HUGGING-FACE-TEXT-CLASSIFICATION
Framework.HUGGING-FACE-SUMMARIZATION
Framework.HUGGING-FACE-TRANSLATION

Additional inputs added to these Hugging Face pipelines will be added as key/pair value arguments to the model’s generate method. If the argument is not required, then the model will default to the values coded in the original Hugging Face model’s source code.

See the Hugging Face Pipeline documentation for more details on each pipeline and framework.
