Description
Hi,
I would like to know if it is possible to convert TensorFlow's tf.signal.fft to the equivalent GPU operation in DALI.
Given a complex tensor as input, tf.signal.fft creates 1D discrete Fourier transform.
From operation reference in DALI docs, I could only find nvidia.dali.fn.spectrogram (i.e., squared magnitude of the STFT coefficients), and I could not perform the desired task (GPU operation equivalent to tf.signal.fft) with this function.
Is there any way to get discrete Fourier transform as in tf.signal.fft?
Thanks a lot.
