Thread: [Matplotlib-users] ImportError: No module named pyplot

Hi,

I am using Ubuntu Gutsy 7.10 and want to use matplotlib.pyplot but when I
execute:

> import matplotlib.pyplot as plt

I get:

>>> import matplotlib.plot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named plot

I installed matplotlib using synaptic.

I found another reference to this problem on Google but no solution.

I cannot find pyplot.py anywhere on my disk.  I can import matplotlib by
itself.

Is there another Ubuntu package I should install?  Is anyone working on a
fix to the matplotlib ubuntu packages?  If so, then does anyone know when
this may be resolved?

Any advice would be appreciated.

Thank you,
Marc

What version of matplotlib do you have?

	import matplotlib
	print matplotlib.__version__

Yes, I did have an typo in when reporting the problem, it should be pyplot
not plot.  However, the problem is with pyplot anyway.  The version of
matplotlib is 0.90.1 as shown here:

  >>> import matplotlib.pyplot as plt
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: No module named pyplot
  >>> import matplotlib
  >>> print matplotlib.__version__
  0.90.1
  >>> 

If this version is to young then how can I get Ubuntu to load a later
version?

Thank you for your response.  Again, I appreciate any help anyone could
provide.

In the early releases of matplotlib, the procedural plotting interface
of matplotlib resided in "pylab", which also mixed in a lot of
numerical routines from numpy and other places.  *After* the release
of 0.90.1, Eric Firing reorganized the plotting functions into a
separate module "matplotlib.pyplot" so people could access them w/o
having to get all of the numpy functions in the same namespace.  See

  http://matplotlib.sourceforge.net/faq/usage_faq.html#matplotlib-pylab-and-pyplot-how-are-they-related

The version you are using is 2 years old, so you may want to consider
upgrading.  But you can get the same functionality with 0.90.1 by
simply

   >>> import pylab as plt

instead of

   >>> import matplotlib.pyplot as plt

JDH

Thank you for the information.  I figured out that using pylab works.  I
would rather use a current version.  I tried to find the version you
mentioned in a deb package for Ubuntu but it doesn't seem to exist.  Do you
know why or where can I get it?

Thank you again.
Marc

Probably there are none for the version of Ubuntu you're using but
there are newer packages in Ubuntu[1].

I'm not a Ubuntu guru, but you seem to be rather old in version, I
suggest, given the short release period, to keep your system
up-to-date to the current version (not 8.10 I think) and there there
are newer binary packages too[2].

Thank you.  I finally upgraded my Ubuntu system, pretty easy, and now pylab
is available.  Thank you to everyone on this thread for your input.

BTW, matplotlib is very nicely done, useful, and appreciated.

here you wrote "plot" not "pyplot": might this be the problem?
