pwgen::PwgenException Driver Error in Jetson nano


I am using deepstream-imagedata-mulitstream for person detection. And for person detection, I am using my custom train yolov4 model. Now I want to create a single exe for my project and for that I am using pyinstaller.

Now in Pyinstaller whenever I am using --ondir command everything is working and exe is generating the model.engine file properly. But when I use --onefile for single exe it is not working and throwing error as given below.

terminate called after throwing an instance of 'pwgen::PwgenException’
** what(): Driver error: **
Fatal Python error: Aborted

So How Can I solve this error ?

Thank you

Could you fill out the following information first?

• Hardware Platform (Jetson / GPU)
• DeepStream Version
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)


• Hardware Platform : Jetson Nano

How to reproduce the issue: Used Deepstream-imagedata-multistream Python module along with yolov4 model for object detection in multiple streams. Now to generate one single exe file I have used pyinstaller. When I use pyinstaller --onefile main.spec file it crashes when engine building module is running. And when I run the script normally using python3 it works properly.


Would you mind attaching the model file with --add-data to see if it helps?
