Update on this: This also no longer works on the R710's CPU. I get the same behavior/error when trying to run ALPR on the R710 as I do on my i7 machine. This absolutely worked in previous versions of CPAI and ALPR.
Blue Iris and CodeProject.AI ALPR

Hmm, Interesting - the Nehalem CPU gen of both desktop + servers appears to be impacted.
Ya. One test I tried was CP 2.1.8 , forget which ALPR version it defaulted to install. But it did start ALPR CPU and didn't crash. But no CUDA there either.
Perhaps its due to newer versions of Paddle bundled with ALPR module. Perhaps Mr. Lud knows the history of paddle versions against ALPR module versions? Maybe earlier paddle version could be used along side current ALPR version? I'm out of my element...

After updating to 2.5.6 I stopped getting plate recognition. In the alert list I think it was showing something about a 500 error. Anyone else have similar issues? Also, what are the latest recommended config details in the AI config for the LPR. I’ve attached my details and also a sample photo. I’ve since reverted back to 2.5.4 but was curious if there was some config modification needed after upgrading. Also, most of the time the motion and LPR works great but sometimes it seems like it will miss just a single vehicle completely. Like it’s asleep at the wheel. No canceled alert, it wasn’t already triggered. Daytime. Easy catch and it just completely misses it. Any suggestions?

I managed to update CP.AI (2.6.2) and ALPR (3.1.0) and now I do have one camera capturing cars going up and down the street.
The behavior didn't change.
If I go into CP.AI Project Explorer and use "Read License Plates" on an image where ALPR can't recognize anything, I get the expected output: "No predictions returned".
But if I choose any image which does have a license plate, the module shuts down.
This is what Event Viewer shows:
Windows 11, CP.AI 2.6.2, ALPR 3.1.0, latest Nvidia Drivers installed on RTX 3090 GPU, the works.
Using YOLOv8 for Object Detection.
ALPR data:
I don't know what else to do to troubleshoot it. Needless to say, the module never worked, even when checking known static images with clearly visible license plates.

What version did you update from and was it working?
ALPR never worked. Every time I tried to have it recognize a license plate, it crashed. Previous version was 3.0.2, but as I was saying, no version I tried worked.
CP.AI and Blue Iris always worked, first with YOLOv5, then with YOLOv8.

You can try running install_cuDNN.bat to update cuDNN. After running install_cuDNN.bat reboot your PC.
I have done that. Updated cuDNN, rebooted my PC, tried again, with exactly the same symptoms.
LE: "YOLOv8 / license-plate" model recognizes the license plate with the same image used.

I notes that the below path is not the default path, it should be just AI. When installing code project did you change the install path?
I had a version prior to AI 2.4.7 which had some issues, and when 2.4.7 came out, I changed the destination directory, because the "AI" one wouldn't work any more, CP.AI was complaining about being unable to install it there.
Since 2.4.7 I used the same folder.
Does ALPR require an absolute path to work?

It should not, but to be sure maybe try uninstall, delete the folders, then reinstall with the default directory.
Installed A2000 into poweredge server with dual E5-2680v3. ALPR CUDA working. CPU mode worked too before I resolved CUDNN issues.
(Used CUDA 12.3 + CUDNN 9. Path to CUDNN bin folder didn't work - duplicated cudnn64_9.dll into new cudnn64_8.dll + put all CUDNN files into C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.3 \ bin + include + lib)
So that confirms it for me - gotta be an issue with old Nehalem CPUs. Good luck.
Well, that solved nothing.
I completely removed CP.AI, deleted all folders, installed from scratch, installed cuDNN, rebooted, started everything up again, the behavior is exactly the same.

ZES_ENABLE_SYSMAN=1@MarioBoo I've been using CP.AI for over a year. It's stable as far as I can see.
Started with v2.0.x, now on v2.6.2.
10 cams using CP.AI for person/vehicle/animal detection. 1 cam for ALPR.
Installed using Windows installer on Win10 machine. Most object detection < 100ms due to Nvidia card.
Same machine as BI5 and Home Assistant. All confirmed AI events sent to Home Assistant to provide triggers for automations.

CP.AI itself is stable, but sometimes when upgrading it has the chance to have an issue. Other than that, mine is very stable, except for the ALPR module, which for some reason would crash on successful attempt to read a plate.
