Fixing 'ALPR_adapter' object has no attribute '_num_items_found'

[alarmatwork]

Whenever I try ALPR module from the the Explorer Iöm gettings folloding error:
13:00:46:Response rec'd from License Plate Reader command 'alpr' (...698964) 13:00:46:License Plate Reader: [AttributeError] : Error during main_loop: Traceback (most recent call last): File "C:\Program Files\CodeProject\AI\modules\ALPR\bin\windows\python39\venv\lib\site-packages\codeproject_ai_sdk\module_runner.py", line 618, in main_loop self.update_statistics(output) File "C:\Program Files\CodeProject\AI\modules\ALPR\ALPR_adapter.py", line 92, in update_statistics self._num_items_found += len(predictions) AttributeError: 'ALPR_adapter' object has no attribute '_num_items_found'

I'm running Module 'License Plate Reader' 3.3.4 (ID: ALPR)

In the ALPR_adapter.py file, do you see this?

[alarmatwork]

Yes, I can see similar code. What should I change ?

I also have the same error - with the same ALPR version.

I can see line 44 setting the _num_items_found variable. I can also see that it's used in two function definitions (status and update_statistics.

I'm not a refined Python developer (yet), but the use of the variable appears to be correct and there don't appear to be any finger fumble spelling mistakes - here are the lines of code where I see it used):

def status(self) -> JSON:
    statusData = super().status()
    statusData["numItemsFound"] = self._num_items_found
    return statusData


def update_statistics(self, response):
    super().update_statistics(response)
    if "success" in response and response["success"] and "predictions" in response:
        predictions = response["predictions"]
        self._num_items_found += len(predictions)

@alarmatwork - so I had the same problem as you - I started looking at options to resolve this and it seems that CUDA library version 11.7 is needed. I downgraded the CUDA library to version 11.7 and voila!
