Control: reopen -1 1026539
theano has been mostly abandoned upstream since 2018. (The Aesara fork
is not abandoned, but includes interface changes including the import
name, so would break reverse dependencies not specifically altered for it.)
It is currently broken (FTBFS due to multiple test failures), probably
by numpy 1.24 (#1027215).
Its reverse dependencies (keras and deepnano) are both also broken by
this. (keras _also_ has apparently unrelated problems, #1026738, and is
orphaned, #1027938.)
This was previously discussed in #1027215, where it was noted that
removing keras would also block the addition of qmean (ITP #976981), but
attempts to fix it failed. (Note that what is in Salsa isn't actually a
fix: theano skips most of its tests in Salsa CI because they take
several hours.)
