python-wlsqm's Issues

Python 3.6 build error

Fails to compile under Python 3.6. See #2.

High priority now that Python 3.4 official support has ended (in March 2019), and many new-ish installed pythons are at least 3.6.

Update contact email

The contact email in setup.py is outdated. PyPI uses it to provide the link to email the maintainer. Update it for the next release.

build error

brilliant work！but I have some problems
python3.6
pip install wlsqm

I try to use this code to form the derivates of my meshless scattered data cloud of CFD.
x is the ndarray[37817,2].
F is the value of x ndarray[37817,].

when input the data in the expertsolver_example.py.
the error occurs:
