Forgive me if this is an old question, but I just loaded mplot3d and was
attempting to work through a couple of the examples on the Matplotlib
website. The problem is that whenever I try to make a call to a function
that requires an argument of projection='3d' (such as: ax =
fig.add_subplot(111, projection='3d')), Python gives me the following error:
Traceback (most recent call last):
File "<pyshell#12>", line 1, in <module>
ax = fig.add_subplot(111, projection='3d')
File "C:\Python26\lib\site-packages\matplotlib\figure.py", line 677, in
add_subplot
projection_class = get_projection_class(projection)
File "C:\Python26\lib\site-packages\matplotlib\projections\__init__.py",
line 61, in get_projection_class
raise ValueError("Unknown projection '%s'" % projection)
ValueError: Unknown projection '3d'
Running help on fig.add_subplot does not show '3d' as a valid projection
type for this function.
What's going on, and how do I fix it?
I'm running Python 2.6.6 on Windows 7.
Thanks in advance.

Check the version of matplotlib you have ! , I suspect a <=1.0

If your version is less than 1.0, the the 3D examples will not work as
is. Instead of gca() with the projection argument, you need to make
an Axes3D object instead.
fig = plt.figure()
ax = Axes3D(fig)
Or something like that (I am working off memory right now).
