It's solved, it's a permission issue.
Thanks to everyone in the Qualcomm AI Hub channel,
I got the following information to solve the problem,
qpm-cli --license-activate qualcomm_ai_engine_direct
qpm-cli --extract qualcomm_ai_engine_direct
qtld-release.aar was successfully obtained.

Awesome, glad the community was able to help solve this issue!

Hello! Can you help me? When I execute the qpm-cli --extract qualcomm_ai_engine_direct command, it returns directly.

Firstly, Qualcomm's relevant agreements must be filled out

https://www.qualcomm.com/agreements

To ensure that QPM3 is installed and has passed Qualcomm's security review,

The data is copied from the qpm3 download page of the official website:
Install QPM3 from https://qpm.qualcomm.com/#/main/tools/details/QPM3
In the terminal, run the following command:

1. qpm-cli --login
2. qpm-cli --license-activate qualcomm_ai_engine_direct
3. qpm-cli -- extract qualcomm_ai_engine_direct (or)
   qpm-cli --extract < the full path to the downloaded .qik file>
   (or)
   From the QPM3 desktop app:
4. Open the QPM3 app on your desktop
5. Go to the Tools page and select Qualcomm® AI Engine Direct SDK

After executing the Give model File as input./moblenet_v3.tflite step, report the following error and how to fix it。
error：
' python build_apk.py -q $QNN_SDK_PATH -m mobilenet_v3_large'
Do you want us to download the model from AI hub (y/n)n
Give model File as input./moblenet_v3.tflite
./moblenet_v3.tflite

Hi @ZhangWeiOneTwo, as mentioned previously the QNNDelegate can be accessed here https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-apps/qnn/linux/2.20.0.240223.zip. It seems like the other error you have pasted above is in relation to not having mobile net_v3 saved / saved in a reference-able location. If you continue to hit issues, please open a new GitHub issue or post in slack, as this issue is closed.

Indeed, you need to reopen a post to discuss new issues.
Okay, I'll write a complete process article and post it on some forums or blogs. It may be slower for about one or two days.

It's solved,
I got the following information to solve the problem,
thanks.
