Dimensions error

[kkdang14]

Dear, Mr. Wang

First, thanks for your pleasant work!

I'm having a little essay on college on your topic but I'm having a problem that Setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (63397,) + inhomogeneous part. I think the error encountered in this function model.calculate_optimal_contraction_pairs_and_cost() specifically self.cost I hope you can show me how to do it

P/s: I preprocessed the obj file to remove vt, vn and kept only f and v

Thank you so much!
