How to use model from local path or git server or S3 storage

Pre-requirement

Run command aws configure to set Access key and Secrete key for S3 storage.

Configure model with custom storage

Enable endpoint_url in model.yaml file to point to custom S3 storage endpoint URL.

# from AWS S3
  initialization:
    s3_mirror_config: 
      # bucket_uri: s3://gpt2/facemodel/  # Must include hash file with commit id in the repo

# from custom S3 storage such as minio
  initialization:
    s3_mirror_config:
      endpoint_url: http://3.107.108.170:9000 # for custom S3 storage endpoint url 
      bucket_uri: s3://gpt2/facemodel/  # Must include hash file with commit id in the repo

# from local path
  initialization:
    s3_mirror_config:
      bucket_uri: /Users/hub/models/gpt2/ # Local path of model with hash file

# from git server
  initialization:
    s3_mirror_config:
      git_uri: https://portal.opencsg.com/models/AIWizards/gpt2.git # git address for git clone

To use the local path of the model, set bucket_uri to the local path. For example: bucket_uri: /Users/home/models/gpt2/.

Make sure there is a file hash include under model path as below.

llm-inference user$ cat /Users/models/opt-125m/hash

To download the model using git clone, set git_uri to the model address.

How to auto download model from OpenCSG Hub

  • Add runtime_env section to model yaml config file.
  • Update model_id according to OpenCSG Model Hub.

For example:

  initialization:
    runtime_env:
      env_vars:
        HF_ENDPOINT: https://hub.opencsg.com/hf
