test failed due to cannot import name 'rand' from 'scipy'

[yuzibo]

Hi,

From Debian build log, we got:

...
> Traceback (most recent call last):
>   File "/<<PKGBUILDDIR>>/interface/tests/python/./check_levelset.py", line 30, in <module>
>     from scipy import rand
> ImportError: cannot import name 'rand' from 'scipy' (/usr/lib/python3/dist-packages/scipy/__init__.py)
> FAIL check_levelset.py (exit status: 1)

I have proposed one patch to fix the issue:

Please help to review it.

TIA.
