I have updated the version of Django to 2.0 in an existing project, and I
have followed all the steps necessary for the project to be compatible.
but I'm having problems in the administrator when creating or editing a
model that uses attributes from this **django-markdownx** library
the current configuration of the project of the usa packages:

the error is caused in this file
{{{
File "/usr/local/lib/python3.6/site-packages/django/forms/widgets.py",
line 114, in merge
...
combined_list = list(list_1)
last_insert_index = len(list_1)
# Walk list_2 in reverse, inserting each element into
combined_list if
# it doesn't already exist.
for path in reversed(list_2):
TypeError: 'set' object is not reversible
...
Local variables in frame
last_insert_index 0
combined_list []
list_2 set(['markdownx/js/markdownx.js'])
list_1 []
}}}
the variable **list_2** is a list of set type
the simple solution that I think
is to convert that variable to a list, or that the function **reversed**,
support that **set** type of data
