Could not run 'aten::std.correction' with arguments from the 'musa' backend

[zhutao1221]

在运行时遇到以下报错，是现在musa不支持吗？
File "/home/zhutao/workspace/StockFormer-main/code/Transformer/utils/metrics.py", line 101, in correlation
return covariance(a, b) / (a.std(unbiased=False).item() * b.std(unbiased=False).item())
NotImplementedError: Could not run 'aten::std.correction' with arguments from the 'musa' backend. This could be because the operator doesn't exist for this backend, or was omitted during the selective/custom build process (if using custom build).
