根因分析

CUDA内核启动时使用了无效参数，通常是因为向CUDA操作传递了零维度张量或非法步幅。

English

A CUDA kernel was launched with invalid arguments, often due to a tensor with a zero dimension or an illegal stride being passed to a CUDA operation.

解决方案

  1. Check tensor shapes and strides before the operation. Ensure no dimension is zero and strides are valid. Print tensor.shape and tensor.stride() to debug.
  2. Use torch.cuda.synchronize() after the operation to get a more detailed traceback.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Restarting the kernel or process does not fix the underlying invalid tensor argument.

  2. 95% 失败

    Increasing batch size or memory allocation does not address the invalid argument error.
