mlab.griddata deprecation!

[fadikar]

ImportError: cannot import name 'griddata' from 'matplotlib.mlab'

[ustroetz]

Hi @fadikar, Thank you for reporting this bug. Could you please provide a little bit of sample code to reproduce the issue?

[MehdiSaffar]

I am having the same issue. The error happens on the import osrm directly, matplotlib version is 3.1.3

[DahnJ]

The problem happens when you have matplotlib version 3.1 or later, instead of 2.2.4 as noted in the requirements. I fixed this by using scipy's griddata instead, i.e. replacing

from matplotlib.mlab import griddata

with

from scipy.interpolate import griddata

in the file osrm/extra.py

Just encountered this, thanks for the solutino @DahnJ

I see its in the master branch, is a new release to PyPi in the offing?

last version of griddata call in https://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.griddata.html has different syntax than currently in extra.py. PR upcoming
