Using Cantools trying to generate a .dbc file

[Azad202222]

Traceback (most recent call last):
File "D:\Python_Codes\venv\lib\site-packages\cantools\database\can\formats\dbc.py", line 1737, in try_remove_attribute
dbc.attributes.pop(name)
TypeError: set.pop() takes no arguments (1 given)

Need help in trying to solve this issue.
dump_file(db, output_file)
After calling dump_file this issue is coming




db object contains the values as shown in the pictures

are you sure that you use an unmodified version of cantools? your message.dbc.attributes is a set, but looking at the DBC loader code, I cannot see how this could happen. (it is supposed to be an OrderedDict.) If you do indeed use an unmodified version, can you boil down your source DBC file to something non-confidential where this still happens?

[Azad202222]

Not using unmodified version... Just installed the packages in Pycharm

[andlaus]

can you provide a non-confidential version of your source DBC file that exhibits this issue?

Im not using source DBC... Getting all the datas by importing from an excel sheet... And mapping those values to the db object... And generating a DBC file. The DBC file only not getting generated.. Throwing error

then this code is wrong: you made the message.dbc.attributes object a set, but it is supposed to be an OrderedDict...

This is the error:

Thanks... After converting it to OrderedDict it is working
