Issues related to arcle's wrappers(BBoxWrapper and PointWrapper)

[bhumikach8989]

Hello Sir,
I am an M.Tech student currently using the ARCLE environment for my project.

When I try to run the examples bbox.py and bboxmini.py provided in the ARCLE repository, I encounter the following error:
AttributeError: 'BBoxWrapper' object has no attribute 'H'

This error occurs immediately when calling env = BBoxWrapper(env).

I have verified that the environment is correctly installed . It seems like the wrapper is trying to access an attribute H that is either missing or not properly initialized.

Could you please help resolve this issue?

Environment Details:

ARCLE version: [ e.g. 0.2.6]

Python version: [e.g., 3.11]

Gymnasium version: [e.g., 1.2.0]

Thank you in advance for your support.

I'm also getting the same error when trying to run the provided example_bbox_mini.py script. Do we need to do some configs before running that? I'd really appreciate some guidance on this. Thanks

It seems the error is caused by gymnasium major release (>=1.0.0), and arcle was tested on gymnasium 0.29.1.
env already contains H, W, and operations property and these could be accessed by referring wrapper instance (self), but behavior has changed in gymnasium>=1.0.0.
Would you change self.H, self.W, self.operations to self.unwrapped.H self.unwrapped.W, self.unwrapped.operations in the bbox.py?
If the issue remains, then feel free to add a comment.
