Function for Python and CLI

Run prediction functions (a.k.a "predictors") locally in your Python apps, with full GPU acceleration and zero dependencies.

[!TIP] Join our waitlist to bring your custom Python functions and run them on-device across Android, iOS, macOS, Linux, web, and Windows.

Installing Function

Function is distributed on PyPi. This distribution contains both the Python client and the command line interface (CLI). To install, open a terminal and run the following command:

# Install Function

[!NOTE] Function requires Python 3.10+

Retrieving your Access Key

Head over to fxn.ai to create an account by logging in. Once you do, generate an access key:

Making a Prediction

First, create a Function client, specifying your access key:

from fxn import Function

# Create the Function client
fxn = Function(access_key="<Function access key>")

Then make a prediction:

# Create a prediction
prediction = fxn.predictions.create(
    tag="@fxn/greeting",
    inputs={ "name": "Peter" }
)
# Print the returned greeting
print(prediction.results[0])

Using the Function CLI

Open up a terminal and login to the Function CLI:

# Login to Function
$ fxn auth login <ACCESS KEY>

Then make a prediction:

# Make a prediction using the Function CLI
$ fxn predict @fxn/greeting --name Peter
