## 区域可用性
<a name="model-card-amazon-titan-text-embeddings-v2-2-regional-availability"></a>

***地区供应情况一览***

**Bedrock 提供三种推断选项：**In-Region**将请求保留在单个区域内以实现严格合规；在尊重数据驻留的情况下跨地理区域（美国、欧盟等）进行地理 Cross-Region路由，以提高吞吐量；以及**全球任何地方的全球 Cross-Region**路由，以便在没有驻留限制的情况下实现最大吞吐量。**有关更多详细信息，请参阅该[区域可用性](models-region-compatibility.md)页面。

您的 AWS 账户具有默认配额，用于维持服务性能并确保适当使用 Amazon Bedrock。分配给账户的默认配额可能会根据地区因素、付款历史记录、欺诈性使用情况、[增加配额请求](https://docs.aws.amazon.com/bedrock/latest/userguide/quotas-increase.html)的 and/or 批准而更新。有关更多详细信息，请参阅[Amazon Bedrock 的配额](quotas.md)文档并查看该模型的[限制](https://docs.aws.amazon.com/general/latest/gr/bedrock.html#limits_bedrock)。

## 示例代码
<a name="model-card-amazon-titan-text-embeddings-v2-2-sample-code"></a>

**第 1 步-AWS 账户：**如果您已有 AWS 账户，请跳过此步骤。如果您不熟悉 AWS，请注册一个 A [WS 账户](https://portal.aws.amazon.com/billing/signup)。

**第 2 步-API 密钥：**前往 [Amazon Bedrock 控制台](https://console.aws.amazon.com/bedrock/home#/api-keys/long-term/create)生成长期 API 密钥。

**第 3 步-获取 SDK：**要使用本入门指南，必须已安装 Python。然后根据您使用的 API 安装相关软件。

```
pip install boto3
```

**第 4 步-设置环境变量：**将您的环境配置为使用 API 密钥进行身份验证。

```
AWS_BEARER_TOKEN_BEDROCK="<provide your Bedrock API key>"
```

**第 5 步-运行您的第一个推理请求：**将文件另存为 `bedrock-first-request.py`
