| labeled_lda.py | xxm, 2019-07-30 08:24 | The project Labeled-LDA-Python (https://github.com/JoeZJH/Labeled-LDA-Python )can work well in Python2. We use 2to3 to convert it into Python3 code. Then the AttributeError shows up | ||

we run the converted Python3 code, the following error will happen:
Traceback (most recent call last):
File "/home/xxm/Desktop/instrument/datasetpy3/Labeled-LDA-Python/example.py", line 50, in <module>
llda_model.save_model_to_dir(save_model_dir)
File "/home/xxm/Desktop/instrument/datasetpy3/Labeled-LDA-Python/model/labeled_lda.py", line 697, in save_model_to_dir
LldaModel._write_object_to_file(save_model_path, save_model.__dict__)
File "/home/xxm/Desktop/instrument/datasetpy3/Labeled-LDA-Python/model/labeled_lda.py", line 650, in _write_object_to_file
print(("%s\n\t%s" % (message, e.message)))
AttributeError: 'TypeError' object has no attribute 'message'
it seems that attributes change between Python2 and Python3. However 2to3 lack for this fix when dealing with exception fix.

1. the message property of PyBaseExceptionObject(Exception) have been cancelled. [1] https://github.com/python/cpython/blob/2.7/Include/pyerrors.h#L13 [2] https://github.com/python/cpython/blob/master/Include/cpython/pyerrors.h#L18 2. `except Exception, e` is a python2.x behavior, pls use `except Exception as e` in python3.x |

Right, the message field on exceptions was removed in python 3 (it was deprecated since Python 2.6). 2to3 can't automatically fix this, because as a static translator it doesn't know that the object on which you are accessing .message is an exception. |
