Transport Layer issues on Raspberry Pi 4

[klastine]

Hi- I am running Ubuntu 20.04 Desktop (64-bit) on a Raspberry Pi 4, trying to run VimbaPython scripts. I followed the install instructions and ran the Install.sh script in the VimbaUSBTL directory and am able to run the viewer successfully. However, upon running any code that tries to access the cameras, I encounter the following:

Traceback (most recent call last): File "list_cameras.py", line 28, in <module> from vimba import * File "/usr/local/lib/python3.8/dist-packages/vimba/__init__.py", line 104, in <module> from .vimba import Vimba File "/usr/local/lib/python3.8/dist-packages/vimba/vimba.py", line 30, in <module> from .c_binding import call_vimba_c, VIMBA_C_VERSION, VIMBA_IMAGE_TRANSFORM_VERSION, \ File "/usr/local/lib/python3.8/dist-packages/vimba/c_binding/__init__.py", line 107, in <module> from .vimba_c import VmbInterface, VmbAccessMode, VmbFeatureData, \ File "/usr/local/lib/python3.8/dist-packages/vimba/c_binding/vimba_c.py", line 674, in <module> _lib_instance = _check_version(_attach_signatures(load_vimba_lib('VimbaC'))) File "/usr/local/lib/python3.8/dist-packages/vimba/c_binding/vimba_common.py", line 484, in load_vimba_lib return platform_handlers[sys.platform](vimba_project) File "/usr/local/lib/python3.8/dist-packages/vimba/c_binding/vimba_common.py", line 503, in _load_under_linux raise VimbaSystemError('No TL detected. Please verify Vimba installation.') vimba.error.VimbaSystemError: No TL detected. Please verify Vimba installation.

I double-checked the env variables and GENICAM_GENTL64_PATH=:/opt/Vimba_5_1/VimbaUSBTL/CTI/arm_64bit is in there. Any help would be greatly appreciated.

Hi Klastine, after installing the VimbaUSBTL I would like to know if you have logged off the system and logged In? I request you to write us an email to [email protected]

I have shut down the system completely and relaunched it, but not specifically logged out and back in. I have been unable to install QT4, could this be causing such an issue?
