failing to import pymba #40

Hi,

I encounter an error while running this very short code:

_#!/usr/bin/env python

import pymba from pymba import *

with Vimba() as vimba: print vimba.getVersion()_

File "test.py", line 3, in import pymba File "/home/dylan/Python/pymba/pymba/init.py", line 2, in from vimba import Vimba File "/home/dylan/Python/pymba/pymba/vimba.py", line 3, in from vimbadll import VimbaDLL File "/home/dylan/Python/pymba/pymba/vimbadll.py", line 44, in with open(vimbaC_path) as thefile: IOError: [Errno 2] No such file or directory: '/home/dylan/Vimba_2_0/VimbaGigETL/CTI/x86_64bit:/home/dylan/Vimba_2_0/VimbaC/DynamicLib/x86_64bit/libVimbaC.so'

When I first installed pymba, this code worked and output was the version number of Vimba, 1.5.0. However, it now gives me the error above. I have installed the GigE and USB transport layers, and the path leading to the file is correct. I cannot fix this problem, I cannot think of any changes I made. The code was working and now it is not.

I have tried deleting pymba, uninstalling the transport layers, and deleting Vimba, then re-installing everything again, but no luck.

I'm using Linux Mint Debian Edition and Python version 2.7. Processor is 1.7 GHz.

That path obviously looks wrong, looks like you're getting two paths returned from the line

vimba_dir = "/".join(os.environ.get("GENICAM_GENTL64_PATH").split("/")[1:-3])

in vimbadll.py. Not sure why.

The quick fix would be to manually put your path into vimbadll.py. Can you post the output of os.environ.get("GENICAM_GENTL64_PATH") on your system?

I get ':/home/dylan/Vimba_2_0/VimbaGigETL/CTI/x86_64bit:/home/dylan/Vimba_2_0/VimbaUSBTL/CTI/x86_64bit'

I found if uninstall the USB transport layer and only have GigETL installed, I can import pymba. GENICAM_GENTL64_PATH is:/home/dylan/Vimba_2_0/VimbaGigETL/CTI/x86_64bit in this case.

EDIT: It also works vice-versa.

I know it has been a while ago. But if you are still interested in a solution please take a look at #58.
