get_frame() fails and crashes Python

[kailiang777]

Hi!

I have been having this problem with PyVCam for a month or two, and any help would be greatly appreciated. I am using a Teledyne Kinetix camera, and the PVCam Test app work great, but I cannot get any Python script using PyVCam to run. I am using the Anaconda Command Prompt (through the administrator). When I run cam.get_frame() or any action involving camera operation, the python terminal pauses, and then shuts down. All the tests in test_camera.py pass.

From previous posts (comment #47), I did install an older version of Build Tools 17.2, and put in the D_DISABLE_CONSTEXPR_MUTEX_CONSTRUCTOR flag, but these problems still persisted. Thanks again! All the technical specs of the set-up are down below:

Windows: 11 Pro
PVCAM Release: 3.10.1
PVCam SDK: 3.10.0
Camera Model: Teledyne Kinetix
Visual Studio version: Visual Studio Build Tools 2022 LTSC 17.2
Python Version: 3.9.15

The tests in test_camera.py just get and set PVCAM parameters. There is no test that would start an acquisition yet.

Does your Command Prompt open upon running the Python app? Or do you open it in advance and run the Python app in it later? In second case the Commapd Prompt should survive anything. Simply no app can kill the the terminal it runs in.

Could you try to run the app in normal Command Prompt (not elevated with admin rights)?

If nothing else helps, try updating to the latest PyVCAM version. There were done some changes recently...
