I’m trying to  inversely design a structure of waveguide by using lumopt, and i follow the example of Y splitter to determine the base structure.Then i modified the python code for topology optimization, but i receive the following error, which i cannot deal with. Can you give me some useful advice? Thanks so much.<\/p>\n
