A simple wrapper to be able to call Kymatio commands via julia. Make sure
your PyCall isn't using the system-wide python, so that you can actually run
pip. If the build isn't working on it's own, you may want to run the
necessary commands on the command line. In the following, substitute root
for the path to your conda environment (the value of Conda.ROOTENV):
> root/bin/conda install pytorch torchvision -c pytorch
> root/bin/pip install kymatio
J=6; Q=16; T = 2^13
x = zeros(T, 5, 3);
t = (range(0,2π,length=T));
for (ii, ω)=enumerate(floor.(Int, range(1,150,length=5))), jj=1:3
x[:,ii,jj] = sin.(ω/jj .* t) + cos.(100*ω/jj .* t.^2)
end
s = Scattering(T, Q=16)
sx = s(x)
meta = compute_meta_scattering(s)
sx[:, meta.order .==1,1,1]
