One more note: changing the plot type from loglog to just plot, the errors
also go away.

Re: [Matplotlib-users] bug report

2015-09-17 Thread Christoph Gohlke

I can reproduce the AttributeError on all Python versions and the crash 
(in Python's _tkinter.pyd extension) on Python 3.4.

As a workaround you might try to upgrade to matplotlib 1.5, which seems 
to work for me.

[Matplotlib-users] How to install matplotlib for python33?

2015-09-17 Thread Zaiwen Gong


Hi,

I am trying to install matplotlib on my RedHat Linux 6.5 with Python33.

Unfortunately, 'matplotlib' rpm isn't available for python33. 
`python-matplotlib` is included only for python2.6 from Red Hat Linux 6.5.

So I try installing the latest module from matplotlib source using 'python 
easy_install'.

#*scl enable python33 'bash'*
#*easy_install -m matplotlib
*
The install finished fine, but I am still get this error when I tried to import 
matplotlib. Is there anything else that I need to config?

# scl enable python33 'python'
Python 3.3.2 (default, Mar 20 2014, 20:25:51)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.

import numpy
import scipy
import matplotlib

Traceback (most recent call last):
  File "", line 1, in 
ImportError: No module named 'matplotlib'


Below is the console when I run "easy_install -m matplotlib".
*At the end, it says "Finished processing dependencies for matplotlib". 
Does that mean matplotlib is not really installed yet?*

Do I miss any steps?

Thank you all.

I am using Python 3.4.3.

I meant to include a pip list:

Assimulo (2.8)
decorator (4.0.2)
gmpy2 (2.0.7)
ipykernel (4.0.3)
ipython (4.0.0)
ipython-genutils (0.1.0)
ipywidgets (4.0.2)
Jinja2 (2.8)
jsonschema (2.5.1)
jupyter-client (4.0.0)
jupyter-core (4.0.4)
MarkupSafe (0.23)
matplotlib (1.4.3)
mistune (0.7.1)
nbconvert (4.0.0)
nbformat (4.0.0)
nose (1.3.7)
notebook (4.0.4)
numpy (1.9.2)
pandas (0.16.2)
path.py (8.1)
pickleshare (0.5)
pip (7.1.2)
Pygments (2.0.2)
pyparsing (2.0.3)
pyreadline (2.0)
python-dateutil (2.4.2)
pytz (2015.4)
pyzmq (14.7.0)

scipy (0.16.0)

simplegeneric (0.8.1)
six (1.9.0)
sympy (0.7.6)
testpath (0.2)
tornado (4.2.1)
traitlets (4.0.0)

So, if the program works for Python 2.7 but not 3.4.3, maybe that is the
problem?  Let me try to install Python 2.7 tonight and see what that does.
