IndexError with Basemap.contour() when using certain projections

Question

I have run into problems when using Basemap.contour with certain projections. Based on the example given in the Basemap documentation, I created the following w

Answer 1

This behavior is according to python3 integer division. Look for examples:

1) python3:

n=100
print (n/2, (n+1)/2)

Output: 50.0 50.5

2) For python 2.7 this code returns 50 50

Solutions:

1) manually update contour and contourf function of basemap with division for python3.

You have to write for integer n: n//2 which is apply division from python2.

2) or run your program with python2.
