Unable to access node_map AcquisitionMode

[rypgis]

Describe the Issue
Hi all, I am new to machine vision integration and have only been using Harvester a short time. I have successfully used Harvester to connect to and get images from a Basler USB camera. Now, I am integrating with a Specim FX17e GigE Vision camera and am having an issue during the image acquisition start command (ia.start()). During this command, the harvester core is unable to access a node value for the AcquisitionMode. When I inspect the node_map using dir(ia.device.node_map), the AcqusititionMode node does not exist. I am able to connect to the device and read the device_info_list.

I am currently using the Stemmer Imaging Common Vision Blox GigE Vision GenTL Producer for the Specim camera. Is it possible this GenTL producer is "blocking" the full node map? When I look at the camera node map within the Common Vision Blox GenICam Browser, the Acquisition Mode is present and the value is "Continuous".

To Reproduce
Steps to reproduce the behavior:

1. Run specimHarvester.py (see code below)

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

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

If yes, please provide a sample code:

from harvesters.core import Harvester
import matplotlib.pyplot as plt
import numpy as np

h = Harvester()
h.add_file(r'C:\Program Files\STEMMER IMAGING\Common Vision Blox\GenICam\bin\win64_x64\TLIs\GEVTL.cti')
h.update()

h.device_info_list[0]
ia = h.create(0)

ia.start()

with ia.fetch(timeout=10) as buffer:
    # Let's create an alias of the 2D image component:

    component = buffer.payload.components[0]
    print(buffer)

    _1d = component.data
    np.savetxt('test.txt', _1d)
    print('1D: {0}'.format(_1d))

    # _2d = component.data.reshape(component.height, component.width)
    # print('2D: {0}'.format(_2d))
    # print(_2d.shape)
    # plt.figure()
    # plt.imshow(_2d)
    # plt.show()

    # print(
    #     'AVE: {0}, MIN: {1}, MAX: {2}'.format(
    #         np.average(_2d), _2d.min(), _2d.max()
    #     )
    # )

ia.stop()
ia.destroy()
h.reset()

If applicable, please paste the actual output (its whole traceback, etc) here:

>>> specimHarvester.py

Expected Behavior
I expect Harvester to connect to the camera and start the image acquisition function.

Configuration

• OS: Windows 11 Enterprise 23H2 (22631)
• Python: 3.8.19
• Harvester: 1.4.3
• GenTL Producer: Stemmer Imaging Common Vision Blox GEVTL.cti
• Camera: Specim FX17e with CUBE processing unit

Reproducibility

This phenomenon can be stably reproduced:

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

This result happens every time I try to connect to the Specim FX17 camera. No issues connecting to the Basler USB camera using the Pylon U3V GenTL Producer.

Actions You Have Taken

• I've read the Harvester FAQ page.
