New to this hardware. Trying to run sample code on Jetson Orin AGX

Jetson Orin AGX
SDK 3.8.2 (Yesterdays Download) 2023-02-06T00:00:00Z
Ubuntu 20.04.5 LTS

I don’t have my camera yet (Zed X) so I’m trying to learn on sample data. Got the SDK installed along with python api and everything else as far as I know. I’m new so it’s all a learning curve. This is the code I used altered from
Using the Video API | Stereolabs
https://support.stereolabs.com/hc/en-us/articles/1500009269601-Are-there-any-video-image-samples-from-the-ZED-products-that-I-can-see-and-test-before-the-purchase-

import sys
from sys import exit
import pyzed.sl as sl 

# Create a Zed Camera object. 
zed = sl.Camera()

# Set SVO path for playback. 
# "/home/j/Downloads/ZED2_HD2K_Runners_H264.svo"
# input_path = sys.argv[1]
init_parameters = sl.InitParameters()
init_parameters.set_from_svo_file("/home/j/Downloads/ZED2_HD2K_Runners_H264.svo")

# Open the Zed
zed = sl.Camera()
err = zed.open(init_parameters)

svo_image = sl.Mat()
while not sys.exit:
  if zed.grab() == sl.ERROR_CODE.SUCCESS:
    
    # Read side by side frames stored in the SVO
    zed.retrieve_image(svo_image, sl.VIEW.SIDE_BY_SIDE)
    
    # Get frame count
    svo_position = zed.get_svo_position();
  elif zed.grab() == sl.ERROR_CODE.END_OF_SVOFILE_REACHED:
    print("SVO end has been reached. Looping back to first frame")
    zed.set_svo_position(0)
    exit()

if I run, after chmoding the file, as
python3 “SVO_Tutorial_One.py” ZED2_HD2K_Runners_H264.svo

Output is this: I have no idea where to look these codes up yet. Any help would be appreciated.

Thanks for your time,

Hi,

Your code probably works, but does not return or print anything.
I suggest you check our python tutorials on GitHub - stereolabs/zed-examples: ZED SDK Example projects
You’ll find other samples of codes that will get values from the depth map, or display it in a window, etc.

I’m going through them and they’re great but at least for my system need small alterations to be drop in and learn. Once I’ve passed through them all, I would be happy to share what worked for me on the AGX. It’s small things like importing the right module not mentioned in the code or adding in a \n in a print() so that the results display properly. Other than that, it’s a lot of fun learning. Thanks for your help.
