Hello everyone,

after running my model (succesfully) I get the following traceback:

Exception ignored in: <function Cplex.__del__ at 0x00000171E25A08B0>

Traceback (most recent call last):

File "C:\Users\Ervin\Documents\Pyprojects\Inventory optimization\inv-opt\lib\site-packages\cplex\__init__.py", line 927, in __del__

File "C:\Users\Ervin\Documents\Pyprojects\Inventory optimization\inv-opt\lib\site-packages\cplex\__init__.py", line 917, in end

AttributeError: 'NoneType' object has no attribute 'freeprob'

Exception ignored in: <function Environment.__del__ at 0x00000171E25649D0>

Traceback (most recent call last):

File "C:\Users\inv-opt\lib\site-packages\cplex\_internal\__init__.py", line 162, in __del__

File "C:\\inv-opt\lib\site-packages\cplex\_internal\__init__.py", line 153, in _end

File "C:\Users\Ervin\Documents\Pyprojects\Inventory optimization\inv-opt\lib\site-packages\cplex\_internal\__init__.py", line 245, in _delete_stream

AttributeError: 'NoneType' object has no attribute 'getchannels'

This leads me to believe this is some kind of bug as nowhere is my code is anything named 'getchannels' nor 'freeprob'. I am using pulp to compile the model and solve it through the python api.

Has anyone encountered something similar?

Kind regards
