'tuple' object does not support item assignment

[btimani]

I am getting the error ('tuple' object does not support item assignment) when I call the solver in the code. I am not sure why I am getting the error in the solve statement because I think that the code checks the validity of the inputs for the model and elements. Please, advise. If of any use, I am using Spyder 3.3.6, Python 3.6.6, Qt 5.9.6,PyQt5 5.9.2, and Darwin 18.7.0 on a Mac. Thank you.

This error is caused by a typo in the last release. In the file linesink.py on line 77 there is a trailing comma that should not be there. If you remove that comma you should be good to go.

You can also install the latest version of ttim by cloning the repository and installing that version. After downloading and unzipping the repo, in a terminal navigate to the ttim directory and then type pip install .
