The suggestion to install matplotlib.basemap seems to be the right direction
to go. However, I have been unsuccessful in importing the file by this
method. This is what I have been trying.
from mpl_toolkits.basemap import Basemap
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab
mpl_toolkits.basemap.NetCDFFile(output.nc, mode='r', maskandscale=True,
cache=None, mmap=True, username=None, password=None, verbose=False)
I am getting the following error as a result.
Traceback (most recent call last):
File "/Users/interpott/Documents/trial.py", line 6, in <module>
mpl_toolkits.basemap.NetCDFFile(output.nc, mode='r', maskandscale=True,
cache=None, mmap=True, username=None, password=None, verbose=False)
NameError: name 'mpl_toolkits' is not defined
How do I force the location of the Netcdf file? and Why am I getting that
mpl_toolkits are not defined?
Thanks for the help,
Jon
