Dear WhiteBreeze,

I'm struggling to get this to work.
First of, I never used python before but I think I managed to get it all up and running.
However I keep getting this out of memory error.
Simple question; do I need more memory =))
This is the end result:
C:\Users\macsh\AppData\Local\Programs\Thonny\lib\site-packages\onnxruntime\capi\onnxruntime_inference_collection.py:56: UserWarning: Specified provider 'CUDAExecutionProvider' is not in available provider names.Available providers: 'CPUExecutionProvider'

You probably need to resize your image to a smaller size, since the error happened while reading the image. Your image has ~640 MB.

Dear Breeze.. WhiteMaster,

Yah, just checked. The image is about 640 Mb.
Doesn't seem that large, in todays day and age.
It was a standard PDF image pull.
What would you recommend as optimal size for the input image size?
Highest regards,
Mac

It's better to have image <10 MB.
Also, oemer doesn't accept PDF file, so you need to transform it into whatever standard image format.
