Same problem:

https://github.com/smvorwerk/xlstm-cuda/blob/main/cuda/kernels/mlstm_kernels.cu#L108

have the same problem too:

b_i is never defined in function mlstm_backward_kernel.

given such compiler error, I'm wondering if this project has ever been built and tested to train on some data at all?
