Hi Andreas,

Sorry, I missed that!  I saw at the bottom of the log:

E   AttributeError: type object 'skimage.feature.orb_cy.array' has no
attribute '__reduce_cython__'

Which is an error that has been fixed in Cython 0.28, supposedly:

https://github.com/cython/cython/issues/1894

But it looks like your compilation is using 0.29, so not sure why that
is happening:

Get: 26 http://deb.debian.org/debian sid/main amd64 cython3 amd64
0.29.14-0.1+b1 [2117 kB]

One possibility is that NumPy was compiled with an older version of
Cython:

https://github.com/cython/cython/issues/1953#issuecomment-398128940

Do you know how I can check the source files for the NumPy 1.17 build
that is used here?

The other errors seem to be because no suitable image plugin is
registered.  This can typically be fixed by installing matplotlib or
imageio beforehand, but it looks like you *do* have matplotlib
installed.  Maybe the Cython module imports break everything so badly
that the plugins cannot even load.

Thanks for updating that; I never had the ability to upload to anything
other than mentors.

Best regards,
