Hi Maintainer

Since the recent upload of python-numpy on 2018-05-05, python-scipy has 
been failing its autopkgtests [1] with the following errors:

======================================================================
ERROR: test_netcdf.test_mmaps_segfault
----------------------------------------------------------------------
Traceback (most recent call last):
   File "/usr/lib/python3/dist-packages/nose/case.py", line 197, in runTest

     self.__dict__['version_byte'] = fromstring(self.fp.read(1), '>b')[0]
DeprecationWarning: The binary mode of fromstring is deprecated, as it 
behaves surprisingly on unicode inputs. Use frombuffer instead
