Source: [https://docs.qualcomm.com/doc/80-70015-15BY/topic/snpe-download.html](https://docs.qualcomm.com/doc/80-70015-15BY/topic/snpe-download.html)
Qualcomm Neural Processing Engine SDK 需要在 Ubuntu 22.04 主机上运行。
Note: 如果主机运行的是 Windows 或 macOS 操作系统软件，须按照 [此处](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-41)提供的步骤安装虚拟机。后续步骤必须在运行 Ubuntu 22.04 LTS 的虚拟机中执行。
Qualcomm Neural Processing SDK 工作流程已通过采用以下配置并运行于物理主机或虚拟机上的 Ubuntu 22.04 进行了验证。
Note: 不支持在基于 Arm 架构的 macOS 操作系统中的 VM 内运行 Ubuntu 22.04。

## Qualcomm Package Manager
Qualcomm Neural Processing Engine SDK 也可以通过 Qualcomm Package Manager (QPM) 下载。本部分将演示如何使用 QPM 下载 Qualcomm Neural Processing Engine SDK。
Note: 如需使用 Qualcomm Package Manager 下载 Qualcomm Neural Processing SDK，应确保用户已经注册了 Qualcomm ID。如果您没有 Qualcomm ID，系统将提示其注册。然后，按照下方说明下载并安装 SDK。
1. 前往 [Qualcomm Package Manager](https://qpm.qualcomm.com/#/main/) 并使用 Qualcomm ID 登录。
2. 导航至 **Tools** 选项卡并在左侧窗格中搜索 *AI Stack*。在筛选结果中，点击 Qualcomm® AI Stack 旁边的箭头，展开可用的 AI 软件 SDK 列表，然后从列表中选择 **Qualcomm Neural Processing SDK**。
3. 点击 **Qualcomm Neural Processing SDK**，导航至下一页。从下拉列表中选择 **Linux** 和 **Version 2.26.2.240911**，然后点击 **Download** 下载 Qualcomm Neural Processing SDK 安装程序。
Note:
- 这些步骤基于版本 2.26.2.240911作为示例。
- 如果使用 Qualcomm Package Manager 桌面工具， **Extract** 按钮则为可见。点击该按钮会自动安装 SNPE SDK。
4. 使用 QPM CLI 工具安装下载的安装程序 (.qik)。
