## Install FastAPI { #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]"

# TF does not support python3.13.
RUN ln -sf /usr/bin/python3.12 /usr/bin/python3
RUN ln -sf /usr/bin/python3.12 /usr/bin/python
RUN ln -sf /usr/lib/python3.12 /usr/lib/tf_python

# Make sure clang is on the path
RUN ln -s /usr/lib/llvm-18/bin/clang /usr/bin/clang

# Link the compat driver to the location if available.

## Sobre os códigos de status HTTP

/// note | Nota

Se você já sabe o que são códigos de status HTTP, pule para a próxima seção.

///

Em HTTP, você envia um código de status numérico de 3 dígitos como parte da resposta.

Esses códigos de status têm um nome associado para reconhecê-los, mas o importante é o número.

	ItemsSkipped uint64
	BytesSkipped uint64

	RetryAttempts uint64

	Finished bool // finished healing, whether with errors or not

	// Add future tracking capabilities

// loadHealingTracker will load the healing tracker from the supplied disk.
// The disk ID will be validated against the loaded one.
