after i installed pymba and allied vision SDK on a linux environment when i execute

from pymba import Vimba, PYMBA_VERSION

i get the following error

`Python 3.5.3 (default, Sep 27 2018, 17:25:39) [GCC 6.3.0 20170516] on linux Type "help", "copyright", "credits" or "license" for more information.

from pymba import Vimba, PYMBA_VERSION Traceback (most recent call last): File "", line 1, in File "/home/pi/.local/lib/python3.5/site-packages/pymba/init.py", line 1, in from .vimba import Vimba, VimbaException File "/home/pi/.local/lib/python3.5/site-packages/pymba/vimba.py", line 5, in from .system import System File "/home/pi/.local/lib/python3.5/site-packages/pymba/system.py", line 1, in from .vimba_object import VimbaObject File "/home/pi/.local/lib/python3.5/site-packages/pymba/vimba_object.py", line 5, in from .feature import Feature, _FEATURE_DATA_COMMAND File "/home/pi/.local/lib/python3.5/site-packages/pymba/feature.py", line 5, in from . import vimba_c File "/home/pi/.local/lib/python3.5/site-packages/pymba/vimba_c.py", line 76, in vimbaC_path = find_so('arm_32bit', 'GENICAM_GENTL32_PATH') File "/home/pi/.local/lib/python3.5/site-packages/pymba/vimba_c.py", line 61, in find_so raise OSError('No libVimbaC.so found') OSError: No libVimbaC.so found `

maybe the environment path is set incorrectly by allied vision ? the current path is GENICAM_GENTL32_PATH=:/home/pi/Vimba_2_1/VimbaGigETL/CTI/arm_32bit

Anyone got an idea what went wrong ?

I have the same issue. Did you manage to fix it? @lonedevwolf

Addressed the issue in the below pull request.

https://github.com/morefigs/pymba/pull/96

It should solve your problem.

morefigs commented 5 years ago

@sudheerExperiments that fix is for Windows, so won't solve this problem.

sudheerExperiments commented 5 years ago

@morefigs, sorry didn't notice that the error was related to linux.

lonedevwolf commented 5 years ago

The issue was that i did not have the right version of vimba installed.

I installed Vimba ARMv7 32 bit and set the GENICAM paths manually since there was some problem with the installer not setting them correctly. Now it is working correctly.

How did you do this? I'm stuck with the same issue on Raspberry Pi. I tried to follow the command they give in the troubleshooting pdf:

export GENICAM_GENTL64_PATH=$GENICAM_GENTL64_PATH:"/PATH_TO_VIMBAFOLDER/VimbaGigETL/CTI/x86_64bit/"

But I'm not sure it worked.

@tmid1 Allied Vision now officially support Python with their cameras, have you tried their software? https://github.com/alliedvision/VmbPy
