Re: bug in solvers/scipy/linearLUSolver.py

[James Pringle]

update -- as of scipy 0.19, linalg.splu had a depreciated option "drop_tol"
which did nothing:
https://docs.scipy.org/doc/scipy-0.19.1/reference/generated/generated/scipy.sparse.linalg.splu.html

As of version 1.0, the keyword seems to have been dropped entirely, and
should be removed from linearLUSolver.py. It had not done anything, and so
can be removed.

This is the only place this keyword exists.

bug in solvers/scipy/linearLUSolver.py

[James Pringle]

Dear all --

I just installed fipy from the conda channel with a fresh install of
anaconda. It is based on python 2.7.14. When I run with the scipy solver it
crashes with

  File
"/home/pringle/anaconda3/envs/MYFIPYENV27/lib/python2.7/site-packages/fipy/solvers/scipy/linearLUSolver.py",
line 64, in _solve_
permc_spec=3)
TypeError: splu() got an unexpected keyword argument 'drop_tol'


splu is loaded from scipy.sparse.linalg, and indeed it does not have the
drop_tol keyword. When I remove the drop_tol keyword, it appears to run as
intended, and produce good solutions for my problem.

However, I am not sure that is the optimal solution...

Worked fine.
Thank you, and apologize for the noise

I suppose the normal way adding  python=2.7
to the conda arguments was tried and did not work?
