I was trying to clone the repository but it seems git can't checkout this commit (f239034d5eb0790ee7639b2523367a71e298fd21) from libigl. What I've tried: - This also happens if I try to clone the smoothing repository (it didn't happen when I did the assignment) - I cloned only the libigl repository and tried to checkout this commit and I got the same error - I can open https://github.com/libigl/libigl/tree/f239034d5eb0790ee7639b2523367a71e298fd21 in the browser just fine
