Help for issues with lazyarray needed

Hi,

I have updated lazyarray in Git[1] (by moving it to Debian Science
team).  The old package was lagging way behind upstream and a Python3
port is available by upstream so I just create the python3-lazyarray
package fixing the open bugs.

Unfortunately there is an open issue[2].  Since the latest upstream
commit has only one failure (in contrast to the latest tagges upstream
version which is according to commit logs not really the latest) I
based the source tarball on the latest commit.  Unfortunately there
is one remaining issue for Python3.7 and two for Python3.8

I continued manually in the pbuilder chroot to get Python3.8 issues:

pbuilder-chroot# cd /build/lazyarray-2.10.0+hg20170630.23ccca1/.pybuild/cpython3_3.8_lazyarray/build; python3.8 -m nose -v test

I somehow suspect that the latter issue is not really hard and I wonder
whether I can get some help from DPMT?

My current plan is to ignore the test suite errors for the moment,
upload a Python3 enabled package to new queue.  Once it has passed new I
will see whether we found some solution for the said issues.  If not
I'll file a new RC bug to prevent testing migration.  I'd like to do
that means to get the latest version of pynn built to keep on with the
Python3 migration for this package.

Any help for the remaining issues is welcome.

Kind regards

      Andreas.
