Layout recognition issue

[gjain7]

Hi ,
I tried ui element detection based on only non_text (ip) and without considering text. Changed self.compos_json = json.load(open(pjoin(self.non_text_dir, self.file_name + '.json'))) instead of merge .
The ui element detection was followed by layout recognition but it was showing some errors as follows ,

TypeError Traceback (most recent call last)

TypeError: expected str, bytes or os.PathLike object, not NoneType

Followed the procedure mentioned in the repo , it would be helpful if some insight on this error can be given
