[Hint: 'cudaErrorLaunchFailure'. An exception occurred on the device while executing a kernel. Common causes include dereferencing an invalid device pointerand accessing out of bounds shared memory. Less common cases can be system specific - more information about these cases canbe found in the system specific user guide. This leaves the process in an inconsistent state and any further CUDA work willreturn the same error. To continue using CUDA, the process must be terminated and relaunched.] (at ../paddle/phi/backends/gpu/cuda/cuda_info.cc:260)

就是两个类别，标签是0，居然还提示错误。。。

你好，看上去是one-hot op存在问题，请前往**官网**提问或者切换其他常用损失。
