## Install FastAPI

The first step is to install FastAPI.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then **install FastAPI**:

<div class="termy">

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

func (b *bufPool) Get() []byte {
	bufp := b.pool.Get().(*[]byte)
	return (*bufp)[:b.sz]
}

func newBufPool(sz int) httputil.BufferPool {
	return &bufPool{sz: sz, pool: sync.Pool{
		New: func() interface{} {
			buf := make([]byte, sz)
			return &buf
		},
	}}
}

// ServeHTTP forwards HTTP traffic using the configured transport
func (f *Forwarder) ServeHTTP(w http.ResponseWriter, inReq *http.Request) {
	outReq := new(http.Request)

    theta_inputs[input_index] = thetaMinus.get();
    TF_RETURN_IF_ERROR(
        RunAndMaybeSum(ctx, forward, theta_inputs, f_outputs, use_function));
    AbstractTensorHandlePtr fMinus(f_outputs[0]);

    // Take Difference of both estimates: (f(theta + eps) - f(theta - eps)).
    TF_RETURN_IF_ERROR(
        ops::Sub(ctx, fPlus.get(), fMinus.get(), f_outputs, "sub_top"));
    AbstractTensorHandlePtr fDiff(f_outputs[0]);

	}
	return
}

	configs := make([]*xdsstatus.ClientConfig_GenericXdsConfig, 0)
	if clientConfig.GetGenericXdsConfigs() != nil {
		configs = clientConfig.GetGenericXdsConfigs()
		return configs
	}

## Structure

Each platform and module has its own source directory under [platforms/](../platforms).
In these source directories, you will find the Gradle projects that make up the platform or module.

The platforms and modules are defined using a DSL in [settings.gradle.kts](../settings.gradle.kts)

     * Sets the POM file of the project to build. Note that providing the path to a POM file via this method will make
     * the model builder operate in project mode. This mode is meant for effective models that are employed during the
