What does this PR do?
In the GOLD algorithm, there is a mapping relationship between the student and the teacher when computing the loss. In the original implementation, this part involved frequent switching between the CPU and GPU, which not only incurred significant time overhead but also easily led to GPU memory fragmentation. This PR fixes this issue by keeping the mapping relationship on the GPU in advance.
