Exception occur when create camera. GenTL exception: Requested operation is not allowed. (ID: -1005)

[Yasirsmb]

Describe the Issue
I have simple program it detect camera but at h.create()/h.create(0) its gives exception

Sample Code
I can show a piece of code that demonstrates the reported phenomenon:

• [ x] Yes
• No
• (Please select either yes or no.)

Here is the code its just test code so see it if create:

from harvesters.core import Harvester
import numpy as np

if __name__ == "__main__":
    h = Harvester()
    h.reset()
    h.add_file('/opt/ImpactAcquire/lib/x86_64/mvGenTLProducer.cti')
    h.update()
    device_info_list = h.device_info_list
    print(device_info_list)
    ia = h.create()
    print("done")

This is the exception i am getting:

Cannot check if IP address available: 'arping' not found

Actions You Have Taken

I have been working in windows with same GenTL and its working fine there a and capturing image. When i came to linux I install same GenTL and try to get initiallize image it always stuck at h.create()

• [ x] I've read the Harvester FAQ page.

Hi @Yasirsmb ,

I just ran into the exact same issue. In my case, the GenICam software that came with my frame grabber was still open and connected to the camera, which prevented the Python script from connecting to the camera. Maybe you could verify that no other software is connected to the camera.
