Error when using zmq camera on jetbot

The jetbot was having an issue with slow framrates, so I tried to use the zmq camera fix, however it gives the following Error:

    ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-4-7eaed894edf3> in <module>
----> 1 from jetbot.camera.zmq_camera import ZmqCamera
      2 
      3 camera = ZmqCamera()  # this should have same interface as current camera

ModuleNotFoundError: No module named 'jetbot.camera.zmq_camera'; 'jetbot.camera' is not a package

I cloned the repo and started the publisher just fine. It gives the following output:

GST_ARGUS: Setup Complete, Starting captures for 0 seconds
GST_ARGUS: Starting repeat capture requests.
CONSUMER: Producer has connected; continuing.

I can manually see the zmq_camera.py file in /jetbot/scripts, so it should have cloned the correct repo.
What could be causing this issue?

Software:
the sd card image based on jetpack 4.3, as it’s the newest one, where object detection actually works.

Sorry for the late response, is this still an issue to support? Thanks

Yes, I have not been able to find any solution to this issue, yet.
