WebLog_softmax 是一个 PyTorch 中的函数，用于计算 softmax 函数的对数值。它将输入张量的每个元素作为指数，计算每个元素的 softmax 值，然后返回这些值的对数。这个函数通常用于分类问题中的损失函数计算。 WebFeb 16, 2024 · Most FFT tools provide a shift function to circularly shift your result so that the 0Hz component is in the center. In pytorch you need to perform torch.fft.fftshift after the FFT and torch.fft.ifftshift right before taking the inverse FFT to put the 0Hz component back in the upper left corner. WebTLDR: PyTorch GPU fastest and is 4.5 times faster than TensorFlow GPU and CuPy, and the PyTorch CPU version outperforms every other CPU implementation by at least 57 times (including PyFFTW). My best guess on why the PyTorch cpu solution is better is that it possibly better at taking advantage of the multi-core CPU system the code ran on. In [1]: seether fur cue
