In the future, we may add support for additional math libraries to support more hardware. See below for where you can request additional hardware support.
Updating from older PyTorch versions
Some PyTorch users might know that older versions of PyTorch also offered FFT functionality with the torch.fft() function. Unfortunately, this function had to be removed because its name conflicted with the new module’s name, and we think the new functionality is the best way to use the Fast Fourier Transform in PyTorch. In particular, torch.fft() was developed before PyTorch supported complex tensors, while the torch.fft module was designed to work with them.
PyTorch also has a “Short Time Fourier Transform”, torch.stft, and its inverse torch.istft. These functions are being kept but updated to support complex tensors.
