[Python-modules-team] Bug#924396: python3-scipy: FutureWarning in scipy.fftpack.ifftn

[Aurelien Jarno]

Package: python3-scipy
Version: 1.1.0-3
Severity: normal
Tags: upstream

scipy.fftpack.ifftn emits the following warning when used:

/usr/lib/python3/dist-packages/scipy/fftpack/basic.py:160: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.
  z[index] = x

This happens for example with the following example from the
documentation:
https://docs.scipy.org/doc/scipy-1.1.0/reference/tutorial/fftpack.html#two-and-n-dimensional-discrete-fourier-transforms

This been upstream fixed by the following commit:
