LogicalErrorException on genicam call

Hi,

When I started the callback.py from samples directory in the repository I gave an error in 18th line:

>>> genicam.Register(camera.GainRaw.Node, callback)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/dmirecki/miniconda3/envs/test/lib/python3.5/site-packages/pypylon/pylon.py", line 3768, in __getattr__
    return self.GetNodeMap().GetNode(attribute)
  File "/home/dmirecki/miniconda3/envs/test/lib/python3.5/site-packages/pypylon/genicam.py", line 1472, in GetNode
    return _genicam.INodeMap_GetNode(self, Name)
_genicam.LogicalErrorException: Node not existing (file 'genicam_wrap.cpp', line 16600)

Do you have any idea what went wrong?

Hi,

The open has to be an uppercase Open. ( Relict from the C++ naming conventions used in pylon)

The error you see is the dynamic node lookup trying to find a node with the name open

Hi, when i call camera.open() it shows error. code:

from pypylon import pylon camera=pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice()) camera.open()

Error:

camera.open() Traceback (most recent call last): File “”, line 1, in File “/usr/local/lib/python3.5/dist-packages/pypylon/pylon.py”, line 1832, in getattr return self.GetNodeMap().GetNode(attribute) File “/usr/local/lib/python3.5/dist-packages/pypylon/genicam.py”, line 1250, in GetNode return _genicam.INodeMap_GetNode(self, Name) pypylon.genicam.LogicalErrorException: Node not existing

Can you help me?

You own a Basler USB3Vision camera. This camera respects the SFNC2.0 standard regarding the names of all features.

The code, that you use is possibly an example for a GigEVision device. [ Which is SFNC 1.x ]

If you want to modify your code use below tables.

There is also the feature “migrationModeEnable” on the USB3 Transportlayer to do the conversion on the fly…
