**• How to reproduce the issue ? **
I am trying to use python demo-apps in deepstream. I pulled docker image nvcr.io/nvidia/deepstream:6.0-devel and copied repo(GitHub - NVIDIA-AI-IOT/deepstream_python_apps: A project demonstrating use of Python for DeepStream sample apps given as a part of SDK (that are currently in C,C++).) and followed HOWTO and built gstreamer. Then installed pyds with pip3 command.

/opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps/apps/deepstream-test1# python3 deepstream_test_1.py sample_qHD.h264

Traceback (most recent call last):

streammux.set_property(‘width’, 1920)
AttributeError: ‘NoneType’ object has no attribute ‘set_property’

Then I remove the cache rm ~/.cache/gstreamer-1.0/registry* and then run gst-inspect-1.0

Please make sure your GPU driver, CUDA version are correct before you install DS 6.0 GA. Quickstart Guide — DeepStream 6.0 Release documentation
