An error when reading LAS file using python lasio

I am trying to read a LAS file in python using lasio. I have a situation where the following code performs without a problem on Windows, but raises an error in MacOS.

import lasio
las = lasio.read('myFile.las')
las = las.df().reset_index()

On Windows, this returns a dataframe as intended. However, when I try the same on Mac, it gives the following error:

Output exceeds the size limit. Open the full output data in a text editor

---> 86     return LASFile(file_ref, **kwargs)

File /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/lasio/las.py:80, in LASFile.__init__(self, file_ref, **read_kwargs)
     71 self.sections = {
     72     "Version": default_items["Version"],
     73     "Well": default_items["Well"],
   (...)
     76     "Other": str(default_items["Other"]),
     77 }
     79 if not (file_ref is None):
...
     69     "COMMA": split_on_comma,
     70 }
---> 72 return splitters[provisional_delimiter]

KeyError: 'TAB'

I can't understand what is causing this error. Appreciate any help.

In that las file, you can change the delimiter from 'TAB' to 'SPACE' and it should fix that issue.
