## Install dependencies { #install-dependencies }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## Using `Jinja2Templates` { #using-jinja2templates }

* Import `Jinja2Templates`.

                .build());
        options.addOption(Option.builder(Character.toString(ACTIVATE_PROFILES))
                .longOpt("activate-profiles")
                .desc(
                        "Comma-delimited list of profiles to activate. Don't use spaces between commas or double quote the full list. Prefixing a profile with ! excludes it, and ? marks it as optional.")
                .hasArg()

## Install FastAPI { #install-fastapi }

The first step is to install FastAPI.

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then **install FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note

    public List<String> getActiveProfileIds() {
        return activeProfileIds;
    }

    /**
     * Sets the identifiers of those profiles that should be activated by explicit demand.
     *
     * @param activeProfileIds The identifiers of those profiles to activate, may be {@code null}.
     * @return This context, never {@code null}.
     */
    public DefaultProfileActivationContext setActiveProfileIds(List<String> activeProfileIds) {

## Install `PyJWT` { #install-pyjwt }

We need to install `PyJWT` to generate and verify the JWT tokens in Python.

Make sure you create a [virtual environment](../../virtual-environments.md), activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

    @Deprecated
    MavenExecutionRequest setActiveProfiles(List<String> profiles);

    /**

You can use [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) with **FastAPI**.

## Install `websockets` { #install-websockets }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `websockets` (a Python library that makes it easy to use the "WebSocket" protocol):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

    pyenv local "3.11"
    export CLOUDSDK_PYTHON=$(pyenv which python3.11)
  else
    echo "Python 3.11 not found, falling back to system python"
    export CLOUDSDK_PYTHON=$(which python3)
  fi
  gcloud auth activate-service-account --key-file="${GOOGLE_APPLICATION_CREDENTIALS}"
fi
set -x

# "TFCI_MACOS_PYENV_INSTALL_ENABLE" controls whether to use Pyenv to install

But you can also install an ASGI server manually.

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then you can install the server application.

For example, to install Uvicorn:

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>
