It did help me with a similar error for YOLOv8 after update to 2.6.5 - that's actually my post in there :)

I am running yolo 5 on my boxes, do we think there will be a patch or something to this? Or we will have to do this manually

No clue. I think NumPy was upgraded to 2.0 while the modules themselves were compiled under NumPy 1.x - hence the error.
I have downgraded NumPy manually to 1.23.0 and managed to revive YOLOv8.
It's actually something that I asked ChatGPT how to fix - and its response helped a lot :)

@MikeLud1 - I just updated to the newest CPAI and the ANPR is not working. Gives this error:

@wittaj see my replies above, I managed to downgrade NumPy to below 2.0 and at least YOLOv8 (which I am using) works.
I expect the same thing to be valid for ALPR, which I admit I gave up on, since I spent an enormous amount of time trying to get working, without success.
What I mean is, it loads, it attempts to detect license plates, and detects nothing, while other (paid) solutions detect license plates from the very same images without issues.
But I digress.

At any rate, what you experience is caused by NumPy being upgraded to 2.0, while the ALPR module itself is compiled with NumPy version smaller than 2.0.
Rather than attempting top recompile the module, I downgraded NumPy, which was easier.

ChatGPT to the rescue

Indeed, different modules have different paths. Other than that, it's the same method.

If I (on my mac)

wget

I can get the index.html which has the links to all the various protobuf versions. Is this an issue on Baidu's part or ???

Someone found that linstalling PaddlePaddle from the venv fixed the issue. It uninstalled protobuf 5.27.2 which got installed with ALPR 3.2.2 and installed protobuf 3.20.2 which is what is needed.

I believe specifically installing CUDA 11.8 does not work, I will try later with CUDA 11.7.

Hi hubbend the link there doesn't work, can you try to find the correct link for me please? :) Thank you

Thanks for the link. ALPR with Cuda 11.8 started OK after I installed PaddlePaddle manually per instruction.
However, ALPR stuck at CPU only, and I had to as well install "pip install PaddlePaddle-gpu" to switch to GPU(CUDA).
I tried the above and got the following error:

ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: 'c:\\program files\\codeproject\\ai\\modules\\alpr\\bin\\windows\\python39\\venv\\Lib\\site-packages\\paddle\\base\\libpaddle.pyd'
Check the permissions.

My install of the non gpu paddle worked well.

Have you tried Command Prompt in Admin mode?

Definitely.
Steps I used to install PaddlePaddle-gpu on my system (similar to instruction in the link except PaddlePaddle-gpu instead of PaddlePaddle):
My CodeProject and BI are on Promox VM Windows 11.
---------------------------------------------
1. Open Command Prompt in Admin mode

2. Run the below commands:

cd \Program Files\CodeProject\AI\modules\ALPR\bin\windows\python39\venv\Scripts
activate
cd C:\Program Files\CodeProject\AI\modules\ALPR
pip install PaddlePaddle-gpu

--------------------------------------

After that I noticed that there were 2 folders: "paddlepaddle_gpu-2.6.1.dist-info" and "paddlepaddle-2.6.1.dist-info" under C:\Program Files\CodeProject\AI\modules\ALPR\bin\windows\python39\venv\Lib\site-packages

See the attached screenshot... no joy.

EDIT: I uninstalled ALPR - deleted the folder and then reinstalled ALPR. Installed Paddle manually and then did the install for the GPU version and this time it worked.

I just installed a Tesla P4 8GB in my unraid server for CP.AI. Pulled this tag codeproject/ai-server:cuda12_2-2.6.5 . Which version of Yolo should I be using for that and is ALPR able to use this GPU?

Apologies in advance if this is common knowledge, but I seem to be having a hard time finding info for this. I just need people, animals, vehicles, and LPR. Is there a succinct answer to this?

Can you explain what the * symbol represents? If I just wanted animals, people, and/or LPR how can I filter out the rest? I get bombarded with flying insect frisbee alerts

I have the similar issue.
CPAI is installed on Promox LXC container with RTX A2000.
I changed the below to force ALPR to use GPU:
1. modulesettings.json:
"GpuOptions" : {
"InstallGPU": true,
2. modulesettings.linux.json:
"ALPR": {
"GpuOptions" : {
"InstallGPU": true
3. ALPR_adapter.py:
def initialise(self) -> None:
# self.can_use_GPU = self.system_info.hasPaddleGPU
self.can_use_GPU = True
4. options.py
# PaddleOCR settings
# self.use_gpu = ModuleOptions.enable_GPU # We'll disable this if we can't find GPU libraries
self.use_gpu = True

Then dashboard shows LPR status with GPU(CUDA), but it seems LPR does not actually use GPU: No change in inference time.
Furthermore, nvidia-smi does not show process PID of LPR, only YOLO.
