ValueError: Buffer and memoryview are not contiguous in the same dimension.

[Jiaqi-knight]

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:

/home/wjq/MeshlessDerivatives/main.py
Traceback (most recent call last):

File "wlsqm/fitter/expert.pyx", line 399, in wlsqm.fitter.expert.ExpertSolver.prepare
ValueError: Buffer and memoryview are not contiguous in the same dimension.

Process finished with exit code 1

Thanks!
