Installation

pip install --upgrade inferless

​
Usage

This client can be used to call Inferless API from your Python code. It supports both synchronous and asynchronous calls.

​
inferless.call

inferless.call(url: str, workspace_api_key: str, data: dict ) -> Response [dict]
This method sends a synchronous request to the Inferless API endpoint

​
Parameters

  • url - Inferless Model API URL
  • workspace_api_key - Inferless Workspace API Key
  • data - Model Input Data in Dict Format
  • inputs (Optional) - Model Input Data in Inference Protocol format, data should not be given is this is given

​
Example

import inferless

URL = "https://<model>.default.model-v2.inferless.com/v2/models/<model>/versions/1/infer"
API_KEY = "76e51......39b57"
data = {"prompt" : "a horse near a beach"}

# This call is synced until the response is returned
result = inferless.call(URL, API_KEY, data)

​
inferless.call_async

inferless.call_async(URL: str, workspace_api_key: str, data: dict, callback=None)
This method sends a request to the inferless endpoint in the background.

​
Parameters

  • url - Inferless Model API URL
  • workspace_api_key - Inferless Workspace API Key
  • data - Model Input Data in Dict Format
  • inputs (Optional) - Model Input Data in Inference Protocol format, data should not be given is this is given
  • **callback - The callback function will be called after receiving the response.
    • callback function should have two params: callback(error, response)
    • error - any error resulting while calling the inferless endpoint
    • response - response from the inferless endpoint

import inferless

URL = "https://<model>.default.model-v2.inferless.com/v2/models/<model>/versions/1/infer"
API_KEY = "76e51......39b57"
data = {"prompt" : "a horse near a beach"}

# callback function which writes the response to a file
def callback_func(e, response):
    # e is the error object
    # response is the response object
    print(response)

# This is not a blocking call and runs in the background and callback function is triggered to write the endpoint response to a file
inferless.call_async(URL, KEY, DATA, callback_func)

​
Using the Inference Protocol format

import inferless

URL = "https://<model>.default.model-v2.inferless.com/v2/models/<model>/versions/1/infer"
API_KEY = "76e51......39b57"
inputs = {
  "inputs": [
    {
      "name": "prompt",
      "shape": [
        1
      ],
      "data": [
        "a horse near a beach"
      ],
      "datatype": "BYTES"
    }
  ]
}

# This call is synced until the response is returned
result = inferless.call(URL, API_KEY, inputs=inputs)
