It looks like CP.AI is not working. Reboot your PC then run this test image to see if CP.AI works

Hey @MikeLud1 Is there any way that I can train the licence-plate model to work a bit better with Australian plates? Although in saying that I've got no clue how but willing to learn.
I've just started running @algertc database system for ALPR which is brilliant way to view things in an organised fashion and whilst your model picks up most plates it seems to get a bit funny with some.. please note a large majority of the plates are correct and it does an amazing job and I am purely wanting to help potentially improve things if I can help at all. Here are some examples
First one, some plates in Australia (In the ACT) have a euro design.
Unsure what happened with this and how it got TEET lol:
A few of the slim-line plates seem to get picked up with an "E" at the start like below I've noticed as well:

Here is one below going past my camera:
Standard European style numberplates must start with the letter 'A' then a space which contains the ACT crest and bluebell logo, then a combination of 6 letters and numbers following the standard ACT 'Y' series format.

Yes and like you I tried to keep it under control using an automation, but I found a better way through BI. Under the AI settings in BI there is an option to restart CPAI every x number of minutes. I set mine to 720 (every 12 hours) and it works great.

ALPR seems to be working, just not with my plate capture. Do I need a better camera? Although, it was working a few iterations ago.

I ran your images through my setup with the same results. I think you've just got a bad angle on your plate captures.
Is that the mainstream? May wanna remove the BI timestamp as that is right in line with potential plates.

Thanks. This will certainly help someone out there! I'm not using Windows for my CodeProject.AI so this won't work for me, unfortunately.
When I use CPAI Explorer, am I using ALPR analysis on my computer or is it using the cloud? In other words, if it works in CPAI Explorer should it also work in BI?

Interesting troubleshooting:
Original test image.
Test image cropped.
Test image cropped and rotated.
Original test image rotated (the full plate is visible).
I am confused.

I'm not exactly sure what the official way to do that is, I'm on a RKNN SBC, so it's a little different if you are running windows.
/app/modules/ALPR-RKNN/modulesettings.json
Has all of the settings, so I'd imagine you'd edit this file and restart the module.
TLDR:
I'm having a similar issue with a newly installed CPAI 2.9.5 and LPR and thought I was losing my mind.
A little more info that may help:
Installed CPAI 2.9.5 with LPR 3.3.4 and Object Detection (YOLOv5.NET) 1.14.0 using the same Windows installer exe on multiple different installs.
The older installs are working fine using the same exact versions. The 2 installs I did over the past few days are experiencing that same problem as JNDATHP
Using CPAI Explorer the Object Detection works fine. Using CPAI Explorer LPR always returns "No prediction returned".
Looking at the logs (with trace) it did find the DayPlate but there is an error with OpenCV
Here is a screenshot of 2 successful Object Detections and then 2 failed LPR
Is it possible one of the dependences is messed up from the source? Like OpenCV or PaddleOCR? Just guessing since I've successfully installed CPAI like 20 times in the past year (lots of testing).
I have uninstalled and reinstalled multiple times in the last 2 days with "Do not use download cache" on and off. I tried both "Check for updates" on and off. Nothing helped.
I've actually successfully installed these same versions a few times a few months so I was surprised this time was giving me such a hard time these past couple of days.
