# Basic Dialog

This section contains tutorials that pertain to running the Llama 2 7B model on HTP within a basic dialog.

## HTP Backend Example Model Config and Backend Extension Config

See [Genie Dialog JSON configuration string](https://docs.qualcomm.com/doc/80-63442-10/topic/dialog_json.html#genie-dialog-json-config-string) for details on the fields and what
they mean. An example model\_config can be found at
`${QNN_SDK_ROOT}/examples/Genie/configs/llama2-7b/llama2-7b-htp.json`. Note that the tokenizer path and
context binary fields will need to be updated based on your actual preparation steps.

**LLaMA model inference on Android**

To run on QNN HTP backend, open a command shell on android and run the following. This assumes that the HTP architecture
has been set (e.g., ARCH=75).

adb shell mkdir -p /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/bin/aarch64-android/genie-t2t-run /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/lib/aarch64-android/libGenie.so /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/lib/aarch64-android/libQnnHtp.so /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/lib/aarch64-android/libQnnSystem.so /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/lib/aarch64-android/libQnnHtpPrepare.so /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/lib/aarch64-android/libQnnHtpNetRunExtensions.so /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/lib/aarch64-android/libQnnHtpV${ARCH}Stub.so /data/local/tmp/
    adb push ${QNN_SDK_ROOT}/lib/hexagon-v${ARCH}/unsigned/libQnnHtpV${ARCH}Skel.so /data/local/tmp/
    adb push <path to htp_backend_ext_config.json> /data/local/tmp/
    adb push <path to llama2-7b-htp.json> /data/local/tmp/
    adb push <path to tokenizer.json> /data/local/tmp/
    adb push <path to model bin files> /data/local/tmp/
    
    # open adb shell
    adb shell
    
    export LD_LIBRARY_PATH=/data/local/tmp/
    export PATH=$LD_LIBRARY_PATH:$PATH
    
    cd $LD_LIBRARY_PATH
    ./genie-t2t-run -c <path to llama2-7b-htp.json>
                    -p "What is the most popular cookie in the world?"
