[Debian-astro-maintainers] Bug#1010215: sympy breaks einsteinpy autopkgtest: name 'numpy' is not defined

[Paul Gevers]

Source: sympy, einsteinpy
Control: found -1 sympy/1.10.1-1
Control: found -1 einsteinpy/0.3.0-2

Dear maintainer(s),

With a recent upload of sympy the autopkgtest of einsteinpy fails in 
testing when that autopkgtest is run with the binary packages of sympy 
from unstable. It passes when run with only packages from testing. In 
tabular form:

                        pass            fail
sympy                  from testing    1.10.1-1
einsteinpy             from testing    0.3.0-2
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of sympy to testing 
[1]. Due to the nature of this issue, I filed this bug report against 
both packages. Can you please investigate the situation and reassign the 
bug to the right package?

DeprecationWarning:
     `np.complex` is a deprecated alias for the builtin `complex`. To 
silence this warning, use `complex` by itself. Doing this will not 
modify any behavior and is safe. If you specifically wanted the numpy 
scalar type, use `np.complex128` here.
