iaparc_inference

The IA Parc inference plugin allows developers to easily integrate their inference pipeline into IA Parc's production module.

Installation

pip install iaparc-inference

Usage

• If your inference pipeline support batching:

  from iaparc_inference import IAPListener
  
  # Define a callback to query your inference pipeline
  # To load your model only once it is recommended to use a class:
  class MyModel:
      def __init__(self, model_path: str):
          ## Load your model in pytorch, tensorflow or any other backend
      
      def batch_query(batch: list, parameters: Optional) -> list:
          ''' execute your pipeline on a batch input
              Note:   "parameters" is an optional argument.
                      It can be used to handle URL's query parameters
                      It's a list of key(string)/value(string) dictionaries
          '''
  
  if __name__ == '__main__':
      # Initiate your model class
      my_model = MyModel("path/to/my/model")
  
      # Initiate IAParc listener
      listener = IAPListener(my_model.batch_query)
      # Start the listener
      listener.run()
  
  

• If your inference pipeline do not support batching:

  from iaparc_inference import IAPListener
  
  # Define a callback to query your inference pipeline
  # To load your model only once it is recommended to use a class:
  class MyModel:
      def __init__(self, model_path: str):
          ## Load your model in pytorch, tensorflow or any other backend
      
      def single_query(one_input, parameters: Optional):
          ''' execute your pipeline on a single input
              Note:   "parameters" is an optional argument.
                      It can be used to handle URL's query parameters
                      It's a key(string)/value(string) dictionary
          '''
  
  if __name__ == '__main__':
      # Initiate your model class
      my_model = MyModel("path/to/my/model")
  
      # Initiate IAParc listener
      listener = IAPListener(my_model.single_query, batch=1)  # Note that batch size is forced to 1 here
      # Start the listener
      listener.run()
  

Features
