根因分析

向cuBLAS函数传递了空句柄（0x0），通常是因为句柄未正确创建或在调用前已被销毁。

English

A null cuBLAS handle (0x0) is passed to a cuBLAS function, typically because the handle was not properly created or was destroyed before the call.

解决方案

  1. Ensure the cuBLAS handle is created before use. In PyTorch, this is typically managed internally, but if using custom CUDA code, call `cublasCreate(&handle)` and check for errors. For PyTorch, reinitialize the model: `model = Model().cuda()`.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Memory tracking is unrelated to handle management.

  2. 80% 失败

    More workers increase the likelihood of handle misuse.
