[Debian-med-packaging] Bug#1029689: emperor: tests fail with scipy 1.10

[Drew Parsons]

Package: emperor
Version: 1.0.3+ds-7
Severity: normal

scipy 1.10 is now available in experimental.
emperor fails debci tests using it.

We are considering uploading scipy 1.10 to unstable in order to
included it in the forthcoming stable release.  If we proceed with
that, then this bug will become Severity: serious.

The errors are ImportError: cannot import name 'PearsonRConstantInputWarning'
A sample from the failing test log is

_____________________ ERROR collecting tests/test_core.py ______________________
ImportError while importing test module '/tmp/autopkgtest-lxc.7__q4ekw/downtmp/autopkgtest_tmp/tests/test_core.py'.
Hint: make sure your test modules/packages have valid Python names.
