# Sample applications

Source: [https://docs.qualcomm.com/doc/80-70017-50/topic/example-applications.html](https://docs.qualcomm.com/doc/80-70017-50/topic/example-applications.html)

The Qualcomm IM SDK includes sample applications that enable you to explore the
            **AI/ML** and **multimedia** features of Qualcomm Linux. Additionally,
            **Python-based samples** are available for common use cases. These applications
        function as a reference for running custom use cases on Qualcomm Linux.

The following groups of sample applications are available for different use cases related
            to retail, AI Edge Box, IP camera, drones, and robotics.

- **AI/ML applications** focus on the AI and ML capabilities.
- **Multimedia applications** are related to the camera, video, and audio
                features.
- **[Python applications](https://docs.qualcomm.com/doc/80-70017-50/topic/python-sample-applications.html)** are the sample applications
                that use Python to run the use cases.

Important:
- Ensure that the host computer uses Ubuntu 22.04.
- The commands in this guide are compatible with Qualcomm Linux 1.3. [Verify your Qualcomm Linux release
                            version](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-253/set_up_the_device.html#check-qualcomm-linux-version).
    If your release version is not 1.3, [flash the latest
                        version](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-253/set_up_the_device.html#flash-software).
- The sample applications and AI procedures in this guide are compatible with
                        the following runtime versions:
    - Qualcomm® Neural Processing SDK – v2.29
    - Qualcomm® AI Engine direct – v2.29
    - TensorFlow Lite (currently known as Lite Runtime or LiteRT) –
                                v2.16.1

    Ensure that you download the matching SDKs to your host computer
                            before starting AI/ML development.
