• Hardware Platform (Jetson / GPU) Jetson nano
• DeepStream Version6.0
• JetPack Version (valid for Jetson only) 4.6
• TensorRT Version 8.0.1
• Issue Type I followed the python bindings from this repository : GitHub - NVIDIA-AI-IOT/deepstream_python_apps: DeepStream SDK Python bindings and sample applications. I want to run de test1 app and I keep getting this error :
