Hello

I have Jetson Nano 4GB development kit.

I have installed Jetson Nano with Ubuntu 20.04 OS image provided by by Qengineering which includes OpenCV with CUDA enabled.

The result of sudo apt show nvidia-l4t-jetson-multimedia-api -a is :

I have followed installation instruction and installed the argus camera library.

I did change the multimedia path in the Setup.py as well as FindTegraMM.cmake to point to "/usr/src/jetson_multimedia_api"

I have also build the argus camera from the /usr/src/jetson_multimedia_api folder and when i execute "argus_camera" from the terminal the programs runs perfectly file.

But when i run the sample.py file I get following error;

from argus_camera import ArgusCamera
Traceback (most recent call last):

ImportError: cannot import name '_argus_camera_cpp' from partially initialized module 'argus_camera' (most likely due to a circular import) (/home/jetson/Downloads/argus_camera-master/argus_camera/init.py)

I would appreciate if you could help resolve this issue.
