pylint #73813 false positive: keyword argument flagged as unexpected in function all [open]

The function called is scipy.linalg.solve which takes among other arguments the keyword 'sym_pos' which states whether one of the positional arguments is symmetric positive.

Running "pylint -E" gives an error message:
src $pylint -E pylint-bug.py
************* Module pylint-bug
E: 13,11:f: Passing unexpected keyword argument 'sym_pos' in function call

However, the program runs without error, so the keyword argument must be valid:
src $python pylint-bug.py
beta= [-6.06466292 0.59873282 0.54583391]

pylint version is 0.24.0:
src $pylint --version
pylint 0.24.0,
astng 0.22.0, common 0.56.1
