IndexError: mode(): Expected reduction dim 0 to have non-zero size

[Surrin1999]

Hello, When I train the model according to your instruction, the following error occurred when I executed the get_spix_gt function. How can I solve it?

PS: My Pytorch version is 1.9.0 and python version is 3.8 (But I don't think this bug is related to the version.)
