weird macro expression value stft_kernel.cu · Issue #9922 · Oneflow-Inc/oneflow · GitHub

我发现 stft_kernel.cu 文件中的代码默认情况下不会被编译，因此怀疑是条件宏出了问题。
于是做了以下修改：doombeaker@1a96e88

#define YCPRINTLOG printf("CUDA_VERSION >= 11000 is true, version: %d, runtime: %d\r\n", CUDA_VERSION, (CUDA_VERSION >= 11000));
#else
#define YCPRINTLOG printf("CUDA_VERSION >= 11000 is false, version: %d, runtime: %d\r\n", CUDA_VERSION, (CUDA_VERSION >= 11000));
#endif

然后再运行（见以下的最小复现代码），发现得到的结果是：

/runonewhisper$ python3 bug_report.py 
CUDA_VERSION >= 11000 is false, version: 11020, runtime: 1

也就是说条件宏确实走的 false 分支，但是运行时的表达式又是 true。

感觉非常诡异。

import oneflow as torch

audio = torch.randn(478214).to("cuda")
N_FFT = 400
HOP_LENGTH = 160
window = torch.randn(400).to("cuda")
stft = torch.stft(audio, N_FFT, HOP_LENGTH, window=window, return_complex=False)
