Mat format error for yelp-chi, snap-patents

[sajqavril]

Dear contributors,

Thanks for your contribution to the community of heterophilic graphs. However, when I try to use yelp-chi data which is downloaded from google drive, I cannot load it correctly using spicy.io.loadmat. I have followed every step of your code and instruction, so could you please give some advice, try yourselves again, or update the dataset?

p.s. the error info looks like:

---------------------------------------------------------------------------

Many thanks and waiting for your response sincerely,
