Package: python-theano Version: 1.0.1+dfsg-2 Severity: serious
(Filing this as RC to give myself time to investigate: I may downgrade it later.)
Memory usage increases over theano's tests, to ~6GB by the end of the python2 set (6981 tests) in Debian sid amd64, and enough to fail the Ubuntu arm64 and ppc64el builds (LP#1769672).
