ImportError: cannot import name 'exConEstimator' from 'fol'

[Martin1007Wang]

Description

I encountered an issue while trying to import exConEstimator from the fol module. It seems that exConEstimator is not defined in the fol module, which leads to an ImportError.

Steps to Reproduce

1. Attempt to import exConEstimator from fol module:

   from fol import exConEstimator

2. Run the script, and you will get the following error:

   Traceback (most recent call last):
     File "/path/to/your/script.py", line X, in <module>
       from fol import exConEstimator
   ImportError: cannot import name 'exConEstimator' from 'fol' (/path/to/fol/__init__.py)
   

Expected Behavior

exConEstimator should be successfully imported from the fol module if it is supposed to be part of the module.

Actual Behavior

An ImportError is raised indicating that exConEstimator is not found in the fol module.

Additional Information

• Module Path: FIT/fol/__init__.py
• Script Path: FIT/QG_FIT.py
• Error Message: ImportError: cannot import name 'exConEstimator' from 'fol'

Possible Solutions

1. Define exConEstimator: If exConEstimator is supposed to be part of the module, please ensure it is defined and properly exported in the __init__.py or the corresponding module file.

2. Documentation Update: If exConEstimator is deprecated or not intended to be part of the module, please update the documentation to reflect this.
