Hi, as Peter Green found out the cloudpickle source package droped Python2 support which makes bug #938494 serious. I guess it would be even harder to drop python-skimage right now since this would affect python-numpy and according to
$ apt-cache rdepends python-numpy | sort | uniq | wc -l 339 reverse dependencies. I have no better solution than just pinging bug #938494 from time to time - and to ping this list to work harder on Python3 migration. Kind regards Andreas. -- http://fam-tille.de
