Dear maintainers,
With a recent upload of blis the autopkgtest of python-scipy fails in
testing when that autopkgtest is run with the binary packages of blis
from unstable. It passes when run with only packages from testing. In
tabular form:
pass fail
blis from testing 0.5.1-5
python-scipy from testing 1.1.0-2
all others from testing from testing
I copied some of the output at the bottom of this report. On a quick
view, similar errors occur for python3.
Currently this regression is blocking the migration of blis 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? If needed, please change the bug's severity.
More information about this bug and the reason for filing it can be found on

def ones(shape, dtype=None, order='C'):
"""
Return a new array of given shape and type, filled with ones.
Parameters
----------
shape : int or sequence of ints
Shape of the new array, e.g., ``(2, 3)`` or ``2``.
dtype : data-type, optional
The desired data-type for the array, e.g., `numpy.int8`.
Default is
`numpy.float64`.
order : {'C', 'F'}, optional, default: C
Whether to store multi-dimensional data in row-major
(C-style) or column-major (Fortran-style) order in
memory.
Returns
-------
out : ndarray
Array of ones with the given shape, dtype, and order.
See Also
--------
ones_like : Return an array of ones with shape and type of input.
empty : Return a new uninitialized array.
zeros : Return a new array setting values to zero.
full : Return a new array of given shape filled with value.
Examples
--------
>>> np.ones(5)
array([ 1., 1., 1., 1., 1.])
>>> np.ones((5,), dtype=int)
array([1, 1, 1, 1, 1])
>>> np.ones((2, 1))
array([[ 1.],
[ 1.]])
>>> s = (2,2)
>>> np.ones(s)
