Describe what you want to implement and what the issue & the steps to reproduce it are:

we just want to run the basler camera via python code but it gives the below error. the camera works in pylon viewer program but it not works in python.

the code: from pypylon import pylon import cv2 camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice()) camera.StartGrabbing(pylon.GrabStrategy_LatestImageOnly) converter = pylon.ImageFormatConverter() converter.OutputPixelFormat = pylon.PixelType_BGR8packed converter.OutputBitAlignment = pylon.OutputBitAlignment_MsbAligned

while camera.IsGrabbing(): grabResult = camera.RetrieveResult(5000, pylon.TimeoutHandling_ThrowException)

if grabResult.GrabSucceded():

image = converter.Convert(grabResult)
img = image.GetArray()

cv2.imshow("video", img)

if cv2.waitKey(1) & 0xFF == ord('q'):
    break
cv2.destroyAllWindows()
cv2.waitKey()

the erorr: Traceback (most recent call last): File "C:\Users\MTS\Desktop\python\test_kamera.py", line 4, in camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice()) File "C:\Users\MTS\AppData\Local\Programs\Python\Python39\lib\site-packages\pypylon\pylon.py", line 1545, in CreateFirstDevice return _pylon.TlFactory_CreateFirstDevice(self, *args) _genicam.RuntimeException: No device is available or no device contains the provided device info properties. : RuntimeException thrown (file 'tlfactory.cpp', line 694)

Is your camera operational in Basler pylon viewer on your platform

Yes

Hardware setup & camera model(s) used

from pypylon import pylon import cv2 camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice()) camera.StartGrabbing(pylon.GrabStrategy_LatestImageOnly) converter = pylon.ImageFormatConverter() converter.OutputPixelFormat = pylon.PixelType_BGR8packed converter.OutputBitAlignment = pylon.OutputBitAlignment_MsbAligned

while camera.IsGrabbing(): grabResult = camera.RetrieveResult(5000, pylon.TimeoutHandling_ThrowException)

if grabResult.GrabSucceded():

image = converter.Convert(grabResult)
img = image.GetArray()

cv2.imshow("video", img)

if cv2.waitKey(1) & 0xFF == ord('q'):
    break
cv2.destroyAllWindows()
cv2.waitKey()

Runtime information:

from pypylon import pylon
import cv2
camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())
camera.StartGrabbing(pylon.GrabStrategy_LatestImageOnly)
converter = pylon.ImageFormatConverter()

    image = converter.Convert(grabResult)
    img = image.GetArray()

    cv2.imshow("video", img)

@thiesmoeller @SMA2016a

[thiesmoeller]

Please edit the sections of issue report Especially what is your camera and Pylon version and Pypylon version and platform

[sulaimansiddiqi233]

@thiesmoeller we are using . pylon viewer 64 bit . pylon release: 7.4.0.14900 camera: acA1300-60gm_23246104 Python : 3.9 64 bit pycharm editer

[SMA2016a]

would you post the IP and Subnet mask of the camera and NIC, please?

This is just a GigE troubleshooting that we are doing here. Nothing related to pypylon.

[sulaimansiddiqi233]

@SMA2016a @thiesmoeller it is localhsot ip : 192.168.1.148 and the mask is : 255.255.255.255

[SMA2016a]

the mask is : 255.255.255.255 -> use the mask is : 255.255.255.0

I have asked for camera and NIC.

[sulaimansiddiqi233]

@SMA2016a we used that mask also. it works in pylon viewer app but not works in pyton code. camera: acA1300-60gm_23246104 Python : 3.9 64 bit. What is NIC?

[SMA2016a]

IP address and Subnetmask of camera and network

[sulaimansiddiqi233]

@SMA2016a our camera works in loca. the ip is 192.168.1.84 mask is : 255.255.255.0 camera: acA1300-60gm_23246104 : Ethernet

[EdithJK]

Just to get it right - IP address and mask from camera and Network interface card (NIC) adapter

NIC 192.168.1.148 and the mask is : 255.255.255.255 CAM 192.168.1.84 and the mask is : 255.255.255.0

Did you change the mask of the network adapter from 255.255.255.255 -> 255.255.255.0 ? The mask for the network adapter also has to be 255.255.255.0

[sulaimansiddiqi233]

@EdithJK i changed the IPs it works in pylon viewers application but it not works in python run program.

[SMA2016a]

please create a tcpdmp file. start tcpdump capture in one console and then start pylon IPconfiguration tool and press 2 times the refresh button. Then close tcpdump and upload the resulting log

[sulaimansiddiqi233]

finally the camera works with pyhton code. i do not know why it gives errors. so now we can work with it. thank you. @SMA2016a @EdithJK @thiesmoeller
