AttributeError when calling nicheformer.pp.basic_preproc()

[yang-lin-pp]

I'm encountering an error when trying to use the nicheformer.pp.basic_preproc() function in the Nicheformer package. The error message is as follows:

AttributeError: module 'nicheformer' has no attribute 'pp'

Steps to Reproduce:

Install the Nicheformer package and its dependencies.

Import the package using import nicheformer.

Attempt to call the preprocessing function with nicheformer.pp.basic_preproc(adata) where adata is an AnnData object.

Expected Behavior:
I expect the preprocessing function to execute without errors and preprocess the AnnData object.

Actual Behavior:
An AttributeError is raised, indicating that pp is not an attribute of the nicheformer module.

Environment:

Nicheformer version: [version number]

Python version: [version number]

Other relevant packages: [list any other packages you're using]

Could you please help me understand why this error occurs, or if there’s a different method I should use to access the preprocessing functions in Nicheformer?

Thank you!
