ImportError: cannot import name 'sort'

[elixirml]

Hello friends
they have done an excellent job, I would like to do a test, I can run the project without problems with the option track = false, but when I activate this option in "true", I get the error

... Tracking-with-darkflow / darkflow / darkflow / net / help.py ", line 84, in camera
     from sort import sort
ImportError: can not import name 'sort'

• I have correctly configured the weights, configuration and the networks folder in -> / Tracking-with-darkflow / deep_sort / resources / networks

• the sort module is located in / Tracking-with-darkflow / sort, next to deep_sort and darkflow.

• The line that is calling the module is like this -> from sort import sort

   maybe I'm doing something wrong, could you help me make it work please

I'm very much thankful
regards
