在运行项目的时候，出现了错误，但是却不知道为什么错误，因为GPU报的错误太抽象

RuntimeError: CUDA error: device-side assert triggered
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

整得人头晕，不知道咋回事

看了文章：

【报错】RuntimeError: CUDA error: CUBLAS_STATUS_EXECUTION_FAILED when calling `cublasLtMatmul( ltHandle,_error: namespace "at::cuda" has no member "getcurr-CSDN博客

得知，应该是我在推理过程中使用了较短的Embedding，导致无法找到该类对应的标签

y = self.y_embedder(y, self.training)

我是直接将y变为了（1,512），但是现在的y的值位于[0-1485]之间，所以导致无法找到该embedding，这种错误，在CPU调试的时候可以出现，但是GPU报错太抽象

解决：

直接删除这一行即可，或者修改nn.Embedding的字典的大小
