How to use Open Source foundation models curated by Azure Machine Learning

  • บทความ

In this article, you learn how to fine tune, evaluate and deploy foundation models in the Model Catalog.

You can quickly test out any pre-trained model using the Sample Inference form on the model card, providing your own sample input to test the result. Additionally, the model card for each model includes a brief description of the model and links to samples for code based inferencing, fine-tuning and evaluation of the model.

How to evaluate foundation models using your own test data

You can evaluate a Foundation Model against your test dataset, using either the Evaluate UI form or by using the code based samples, linked from the model card.

Evaluating using the studio

You can invoke the Evaluate model form by selecting the Evaluate button on the model card for any foundation model.

Each model can be evaluated for the specific inference task that the model will be used for.

Test Data:

  1. Pass in the test data you would like to use to evaluate your model. You can choose to either upload a local file (in JSONL format) or select an existing registered dataset from your workspace.
  2. Once you selected the dataset, you need to map the columns from your input data, based on the schema needed for the task. For example, map the column names that correspond to the 'sentence' and 'label' keys for Text Classification

Compute:

  1. Provide the Azure Machine Learning Compute cluster you would like to use for fine-tuning the model. Evaluation needs to run on GPU compute. Ensure that you have sufficient compute quota for the compute SKUs you wish to use.

  2. Select Finish in the Evaluate form to submit your evaluation job. Once the job completes, you can view evaluation metrics for the model. Based on the evaluation metrics, you might decide if you would like to fine-tune the model using your own training data. Additionally, you can decide if you would like to register the model and deploy it to an endpoint.

Evaluating using code based samples

To enable users to get started with model evaluation, we have published samples (both Python notebooks and CLI examples) in the Evaluation samples in azureml-examples git repo. Each model card also links to evaluation samples for corresponding tasks

How to fine-tune foundation models using your own training data

In order to improve model performance in your workload, you might want to fine tune a foundation model using your own training data. You can easily fine-tune these foundation models by using either the fine-tune settings in the studio or by using the code based samples linked from the model card.

Fine-tune using the studio

You can invoke the fine-tune settings form by selecting on the Fine-tune button on the model card for any foundation model.

Fine-tune Settings:

Fine-tuning task type

  • Every pre-trained model from the model catalog can be fine-tuned for a specific set of tasks (For Example: Text classification, Token classification, Question answering). Select the task you would like to use from the drop-down.

Training Data

  1. Pass in the training data you would like to use to fine-tune your model. You can choose to either upload a local file (in JSONL, CSV or TSV format) or select an existing registered dataset from your workspace.

  2. Once you've selected the dataset, you need to map the columns from your input data, based on the schema needed for the task. For example: map the column names that correspond to the 'sentence' and 'label' keys for Text Classification

  • Validation data: Pass in the data you would like to use to validate your model. Selecting Automatic split reserves an automatic split of training data for validation. Alternatively, you can provide a different validation dataset.
  • Test data: Pass in the test data you would like to use to evaluate your fine-tuned model. Selecting Automatic split reserves an automatic split of training data for test.
  • Compute: Provide the Azure Machine Learning Compute cluster you would like to use for fine-tuning the model. Fine-tuning needs to run on GPU compute. We recommend using compute SKUs with A100 / V100 GPUs when fine tuning. Ensure that you have sufficient compute quota for the compute SKUs you wish to use.
  1. Select Finish in the fine-tune form to submit your fine-tuning job. Once the job completes, you can view evaluation metrics for the fine-tuned model. You can then register the fine-tuned model output by the fine-tuning job and deploy this model to an endpoint for inferencing.

Fine-tuning using code based samples

Currently, Azure Machine Learning supports fine-tuning models for the following language tasks:

  • Text classification
  • Token classification
  • Question answering
  • Summarization
  • Translation

To enable users to quickly get started with fine-tuning, we have published samples (both Python notebooks and CLI examples) for each task in the azureml-examples git repo Finetune samples. Each model card also links to fine-tuning samples for supported fine-tuning tasks.

Deploying foundation models to endpoints for inferencing

You can deploy foundation models (both pre-trained models from the model catalog, and fine-tuned models, once they're registered to your workspace) to an endpoint that can then be used for inferencing. Deployment to both serverless APIs and managed compute is supported. You can deploy these models by using either the Deploy UI wizard or by using the code based samples linked from the model card.

Deploying using the studio

You can invoke the Deploy UI form by selecting the Deploy button on the model card for any foundation model, and selecting either Serverless API with Azure AI Content Safety or Managed Compute without Azure AI Content Safety

Deployment settings

Since the scoring script and environment are automatically included with the foundation model, you only need to specify the Virtual machine SKU to use, number of instances and the endpoint name to use for the deployment.

Shared quota

If you're deploying a Llama-2, Phi, Nemotron, Mistral, Dolly or Deci-DeciLM model from the model catalog but don't have enough quota available for the deployment, Azure Machine Learning allows you to use quota from a shared quota pool for a limited time. For more information on shared quota, see Azure Machine Learning shared quota.

Deploying using code based samples

To enable users to quickly get started with deployment and inferencing, we have published samples in the Inference samples in the azureml-examples git repo. The published samples include Python notebooks and CLI examples. Each model card also links to Inference samples for Real time and Batch inferencing.

Import foundation models

If you're looking to use an open source model that isn't included in the model catalog, you can import the model from Hugging Face into your Azure Machine Learning workspace. Hugging Face is an open-source library for natural language processing (NLP) that provides pre-trained models for popular NLP tasks. Currently, model import supports importing models for the following tasks, as long as the model meets the requirements listed in the Model Import Notebook:

  • fill-mask
  • token-classification
  • question-answering
  • summarization
  • text-generation
  • text-classification
  • translation
  • image-classification
  • text-to-image

Note

Models from Hugging Face are subject to third-party license terms available on the Hugging Face model details page. It is your responsibility to comply with the model's license terms.

You can select the Import button on the top-right of the model catalog to use the Model Import Notebook.

Screenshot showing the model import button as it's displayed in the top right corner on the foundation model catalog.

The model import notebook is also included in the azureml-examples git repo here.

In order to import the model, you need to pass in the MODEL_ID of the model you wish to import from Hugging Face. Browse models on Hugging Face hub and identify the model to import. Make sure the task type of the model is among the supported task types. Copy the model ID, which is available in the URI of the page or can be copied using the copy icon next to the model name. Assign it to the variable 'MODEL_ID' in the Model import notebook. For example:

Screenshot showing an example of a hugging face model ID ('bert-base-uncased') as it's displayed in the hugging face model documentation page.

You need to provide compute for the Model import to run. Running the Model Import results in the specified model being imported from Hugging Face and registered to your Azure Machine Learning workspace. You can then fine-tune this model or deploy it to an endpoint for inferencing.
