In class 'augmentedImageDatastore', the get method for Dependent property 'NumObservations' attempts to access the stored property value. Dependent properties don't store a value

Hi John,
If you’re getting strange or unexpected errors like the one, you're seeing. There are good chances that MATLAB is not using the built-in version of “augmentedImageDatastore” but instead using a custom version in your path.
Run the following in MATLAB:
which("augmentedImageDatastore")
This command will tell you where MATLAB is finding the definition of “augmentedImageDatastore”.
