Seems upgrading basemap to V 1.0 has solved it. So now I have: In [1]: import mpl_toolkits.basemap as Basemap In [2]: Basemap.__version__ Out[2]: '1.0' In [3]: import matplotlib as mpl In [4]: mpl.__version__ Out[4]: '1.0.0'
And the tutorial runs smoothly. --john On Thu, Oct 28, 2010 at 10:30 PM, Benjamin Root <ben.r...@ou.edu> wrote: > On Thu, Oct 28, 2010 at 3:16 PM, John <washa...@gmail.com> wrote: >> >> Hello, I've been using basemap with plt.colorbar for sometime, but I >> just recently started to have the problem of: >> AttributeError: 'NoneType' object has no attribute 'autoscale_None' >> >> I ran the fcstmaps.py example (GREAT EXAMPLE by the way), and here is >> the full error I get: >> >> Traceback (most recent call last): >> File "fcstmaps.py", line 92, in <module> >> plt.colorbar(cax=cax, orientation='horizontal') >> File "/matplotlib/pyplot.py", line 1519, in colorbar >> ret = gcf().colorbar(mappable, cax = cax, ax=ax, **kw) >> File "/matplotlib/figure.py", line 1180, in colorbar >> cb = cbar.Colorbar(cax, mappable, **kw) >> File "/matplotlib/colorbar.py", line 706, in __init__ >> mappable.autoscale_None() # Ensure mappable.norm.vmin, vmax >> AttributeError: 'NoneType' object has no attribute 'autoscale_None' >> >> I did upgrade matplotlib recently to version 1.0.0 >> >> Basemap is 0.99.4 >> >> Thanks, >> john >> > > John, > > It appears the problem is in matplotlib, somehow...
