without“DETECTOR.INI” #57

Open Buantum opened 8 months ago

I try to load dll files to initialize Python class with code

1697988119124

However, it returns 20002 which means failed. I find that there is no “DETECTOR.INI” files in Andor SDK files which is necessary for initialize. So I learn the code of pylablib which also needs ini_path for class AndorSDK2camera. but why I run pylablib successfully eventhough there is no “DETECTOR.INI”？

Hi!

Acutally, according to the documentation 20002 is the "success" error code (which, I agree, is unconventional): image Regarding DETECTOR.INI: as far as I know, it is only requires for some specific cameras, mostly older models. Hence, by default pylablilb just supplies an empty string. According to the documentation, if the path is indeed required, and it's not supplied, the Initialize function will return DRV_INIERROR error (20070). However, I've never worked with such cameras, so I can't say what the actual behaviour would be.

thanks for your reply！ I have found such an conventional thing today which troubles me with “error”
