# Function for Python

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

> [!TIP]

> [Join our waitlist](https://fxn.ai/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:

```sh

# Install Function

$ pip install --upgrade fxn

```

> [!NOTE]

> Function requires Python 3.10+

## Retrieving your Access Key

Head over to [fxn.ai](https://www.fxn.ai/account/developer) to create an account by logging in. Once you do, generate an access key:

![generate access key](https://raw.githubusercontent.com/fxnai/.github/main/access_key.gif)

## Making a Prediction

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

```py

from fxn import Function

# Create the Function client

fxn = Function(access_key="")

```

Then make a prediction:

```py

# 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:

```sh

# Login to Function

$ fxn auth login 

```

Then make a prediction:

```sh

# Make a prediction using the Function CLI

$ fxn predict @fxn/greeting --name Peter

```
