OSError

[nsjones11]

Hi, currently just exploring the VimbaPython and was just trying to run the list_camera.py to check I have my environment setup correctly. I keep running into 'OSError: exception: access violation writing 0x00FEE9A0'. The error code changes each time. I'm running Python 3.8 32-bit on Windows 10. VimbaPython is present in my site packages.

Error Occurs during the self_startup() after it calls call_vimba_c('VmbStartup')

Any thoughts on this?

Hello, what Vimba version do you have installed? Does the camera stream with Vimba Viewer? Cheers, Teresa

Hi,

I have the latest drivers based off the updater, Vimba 6.0, and the camera does stream with the Vimba Viewer. I am using the 1800 U-500c with firmware 00.10.00.6c9062b1.

cheers!

Hi, thanks for checking that, it rules out a faulty installation or missing environmental variables. I think I have a hunch where the problem lies, though. If your Windows operating system is 64-bit, it is recommended to use a 64-bit interpreter as well. Can you check if that solves the error message? Other than that it all looks good. Cheers, Teresa

I actually did try a 64-bit python version and it resulted it in the same error. I also try different python versions(3.7 and 3.9) since I was unsure if there maybe an issue in 3.8, but again same error. I can try again the 64-bit version just to confirm.

I looked up similar issues in our Support Portal, bt it seems to have been specific issues with either the Python version or a 32-bit incompatiblity. Unless the problem was resolved, I can only suggest to reinstall Python and VimbaPython and make sure that the right Python version is linked/used. Else, try installing Vimba Python without numpy or opencv -> install those seperately.
