Function for Python and CLI

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

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:

Making a Prediction

Let's run the @fxn/greeting predictor which accepts a name and returns a congenial greeting. Run the following Python script:

from fxn import Function

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

[!TIP] Explore public predictors on Function or create your own. r

Using the Function CLI

Open up a terminal and run the following command:

# Login to Function
fxn auth login <ACCESS KEY>

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