Lux cannot import 'bmat' from SciPy

[SimonCrouzet]

Hello everyone,

Thanks for your work on the package!

I am encountering a problem when I am trying to import lux v0.5.1:

>>> import lux

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

ImportError: cannot import name 'bmat' from 'scipy.sparse.sputils' ([c:\ProgramData\Anaconda3\envs\dla\lib\site-packages\scipy\sparse\sputils.py](file:///C:/ProgramData/Anaconda3/envs/dla/lib/site-packages/scipy/sparse/sputils.py))

An issue in an other package is mentioning the same problem. It seems to come from a commit within scipy. However, it's strange because I have scipy v1.4.1 (which I tried to update but it's apparently not possible, and I think only lux is requiring it in my local env), and this commit is attached to scipy v1.10.1.

Wishing you a pleasant day,
Best,
