Hello Everyone, I just bought an Oak-D Lite. I have a raspberry Pi 4B with 8 GB RAM running Linux Raspberry PI 6.1.21.v8+. I downloaded all packages that...

Where do I find the pipeline graph tool? What do I need to execute it?

Hi BrianHouse
Sorry for not linking to the repo. Here.
Run it using pipeline_graph run "python3 <name of script>.

Thanks,
Jaka

Here is the output from first running mono_preview.py which does work:

(base) Brians-MacBook-Pro:examples brianhouse$ pipeline_graph run "python3 MonoCamera/mono_preview.py"

Pipeline schema retrieved

Program exited.

0. MonoCamera.out (10) -> XLinkOut.in (2)

1. MonoCamera.out (6) -> XLinkOut.in (1)

Here is the output from rgb_preview.py which does not work:

(base) Brians-MacBook-Pro:examples brianhouse$ pipeline_graph run "python3 ColorCamera/rgb_preview.py"

Pipeline schema retrieved

Program exited.

0. ColorCamera.preview (8) -> XLinkOut.in (1)

Hi BrianHouse ,
We apologize for taking this long to debug.. Could you just try the last thing, the cam_test.py, and copy the terminal output? My guess is that ColorCam is connected, but will stream 0 FPS, which means the cable isn't properly connected on the PCBA. In such case, we will replace the device asap.
Sorry again!

Are there other modules I am going to need"?

(base) Brians-MacBook-Pro:tests brianhouse$ python3 cam_test.py

Traceback (most recent call last):

File "cam_test.py", line 45, in <module>

import cam_test_gui

ModuleNotFoundError: No module named 'cam_test_gui'

(base) Brians-MacBook-Pro:tests brianhouse$

also I noticed it has a lot of options which ones do you want me to run?

BrianHouse

ok, I figured out all the dependencies. I have Camera Test working. I guess I take all the defaults to the prompts and 'connect' to the device"?

Hi BrianHouse
Yeah, seems like a connection issue on rgb (note the 0 | 0 on rgb). Could you write to support@luxonis.com, so we can replace the camera.
Thanks and sorry for the inconvenience.

Regards,
Jaka

Sure thanks for all your help Erik and Jaka!

How long did it take to get your replacement?

Another one with the same issue. Super frustrating way to run support on a forum!

Hi Adam,

I have not received it yet. I also asked them for tracking info which I have not received yet.
