tensorflow-nufft 0.8.0

A fast, native non-uniform FFT op for TensorFlow.

TensorFlow NUFFT is a fast, native non-uniform fast Fourier transform op for TensorFlow. It provides:

• Fast CPU/GPU kernels. The TensorFlow framework automatically handles device placement as usual.

• A simple, well-documented Python interface.

• Gradient definitions for automatic differentiation.

• Shape functions to support static shape inference.

The underlying algorithm is based on the NUFFT implementation by the Flatiron Institute. Please refer to FINUFFT and cuFINUFFT for more details.

Installation

You can install TensorFlow NUFFT with pip:

$ pip install tensorflow-nufft

Note that only Linux wheels are currently being provided.
