Severity: serious
Control: tags -1 patch

Many Theano operations include C code for speed; the compilation process uses an undocumented Numpy function to check ABI compatibility.

In Numpy 1.16 (recently added to sid), this function is moved, causing all compiles to fail: https://ci.debian.net/data/packages/unstable/amd64/t/theano/latest-autopkgtest/log.gz
