Describe the Bug I am using Ranger3 Sick (3d machine vision camera) with Ubuntu 18.04. I have *.cti file from their Linux SDK. I am able to load cti file through harvester and get Camer info. but when I try to fetch_buffer I am gettig the following error. _genapi.RuntimeException: Invalid layout of buffer attached to chunk parser! : RuntimeException thrown (file 'ChunkAdapterGEV.cpp', line 99)

I have used following code

from harvesters.core import Harvester import numpy as np h = Harvester() h.add_file("sickGenTLProducer.cti") h.update() print(len(h.device_info_list)) print(h.device_info_list[0]) ia = h.create_image_acquirer(0) ia.start_acquisition() with ia.fetch_buffer() as buffer: print(buffer)

1. Connect Ranger3 sick camera with Ubuntu system.
2. Build Linux sdk from sicksupportportal

4. Use the code from harvester for image aquisition
5. See error
