matplotlib and numpy install errors

[Bio]

Hello, I am trying to install matplotlib and numpy on a new Mac. I had
no difficulty downloading and installing PyYAML and NLTK. Python 2.6
came already installed on the system. I was able to download both
matplotlib and numpy without difficulty however when I try to install
either of them I get the error message:

matplotlib 1.01.1-r0 can't be installed on this disk
matplotlib requires System Python 2.6 to install

I get the same error message when I try to install numpy

I have verified that I do have one version of Python only and it is
2.6.1. Does anybody have any idea how to resolve this problem? Thanks,
George

Hi Richard, Thank you for your reply. I have to admit I am extremely
reluctant to install a second version of Python on my system. When I
originally set up nltk on my previous Mac I unknowingly installed a
second version of Python before I tried to install nltk. It took a lot
of work to get the system to work and I still have problems because of
that dual Python install. What I am hoping to do is install numpy and
matplotlib with just the single Python 2.6.1 on my system without
having to install 2.7.1 as well. If I understood your post you are
recommending doing a Python 2.7.1 install before installing numpy and
matplotlib. Is it possible to install numpy and matplotlib with 2.6.1?
I did an easy_install and numpy seemed to install although there were
some error messages, the matplotlib did seem to easy_install at all.
Sincerely, George

I see that there's a new version of matplotlib since my note and it appears that the "matplotlib requires System Python 2.6 to install" message in your case comes from the mkpg. What I'd suggest is to try

easy_install matplotlib

(which might require sudo, always a worry) and you'll need to mess with your PYTHONPATH to make sure you have things right.

If that get's you past the 'requires 2.6 to install' and matplotlib examples work, you're done. If, however, you still have problems check  step 7 from the link for the corrections that need to be made to matplotlib 0.91 to see if they apply to this version.

I'd still give consideration to doing the 2.7.1 thing, though; I've found it much easier to manage Python packages by having them under /usr/local in general and using virtualenv keeps you even more organized. Do not, however, touch the system 2.6 or you'll have no end of grief. The brew method will save you from that.

Hey Bio,
try to download the numpy source build and compile (on extraction, the following steps should be enough)
$ cd <extracted_numpy_folder>
$ ./configure
$ make
$ sudo make install

If that doesn't help, use macports (a dmg is available for macports installation)
$ sudo port install python-numpy

a dependency tree is built up for other libraries used by matplotlib such as ATLAS, BOOST, etc.

I hope that helps...

Hi Richard, Thank you for your response. Unfortunately I am still
unable to get working versions of numpy or matplotlib. When I perform
an easy_install for both numpy and matplotlib the install proceeds but
several error messages occur. Then when I try to use matplotlib I get
error messages indicating the matplotlib is not present. Here is the
output I get when I try to use matplotlib:

ValueError: The plot function requires the matplotlib package (aka

I also tried to use step 7 from your link but I couldn't get terminal

from the first cd command you cite:

You wouldn't find the site package with

-bash: cd: /usr/local/Cellar/python/2.6.1/lib/python2.6/site-packages/

 
unless you installed 2.6.1 there using brew. One of the huge headaches with the system install is knowing where to find site-packages. Try

/Library/Python/2.6/site-packages

However, that may not be what's throwing your

ValueError: The plot function requires the matplotlib package (aka
pylab).See http://matplotlib.sourceforge.net/

if you are using matplotlib 1.01

I tried installing that and got the message and got as far further as a message indicating "wrong architecture" when I threw up my hands and reverted to 0.99. Unfortunately, I don't know how to retrieve that version from the official site.

There's very little to make sense. You can easily navigate the site and read around a little bit especially the FAQ's : http://www.enthought.com/products/epdfaq.php#EPDvsETS

An academic version of EPD is available for free download here: http://www.enthought.com/products/edudownload.php

It contains bundles of most python packages including numpy and matplot lib. Give it a shot.

Hi Victor, Thanks for your response. I tried to implement your first
suggestion but unfortunately could not get past the first step. I
don't really have an extracted numpy folder, it is during the
extraction process that I encounter the error message indicating I
have to have Python 2.6 to proceed. If I try the cd command with the
unextracted numpy location I just get an error: Here is my attempt:

Last login: Wed Jun 29 13:44:23 on ttys000
George-Ortons-Mac-Pro:~ BioASys$ cd /Users/BioASys/Downloads/

-bash: cd: /Users/BioASys/Downloads/matplotlib-1.0.1-python.org-py2.6-
macosx10.3.dmg: Not a directory
George-Ortons-Mac-Pro:~ BioASys$


So I am not sure how to proceed further with your first suggestion.
When I try your second suggestion I also get an error message. I do
have MacPorts on my system. Here is the output I get when i try to do
the macports install:

George-Ortons-Mac-Pro:~ BioASys$ sudo port install python-numpy
Password:
Error: Port python-numpy not found
To report a bug, see <http://guide.macports.org/#project.tickets>
George-Ortons-Mac-Pro:~ BioASys$


Thank you for the suggestions but unfortunately I still can't seem to
install numpy or matplotlib on my system. What seems particularly odd
to me is that the error message I get when I try to install either
numpy or matplotlib is that Python 2.6 needs to be present for the
installs to proceed and I do in fact have Python 2.6 and only Python
2.6 on my system. Thanks again for your help. Sincerely, George

Hi Correa, I've looked through the site but I still don't get most of
it. It looks like I would be downloading an additional (2.7.1) version
of Python along with several other packages. I am extremely hesitant
to download and install an additional version of Python on my system.
I accidentally did that on my old mac and had no end to the problems
it caused me. Am I correct in believing that if I do the enthought
download that I will be installing a second Python 2.7.1 on my system?
Thanks for your help. Sincerely, George

[Richard Careaga]

George, you may not be able to dig yourself out of this hole with the
tools you have. You can't change directories thusly

-bash: cd: /Users/BioASys/Downloads/matplotlib-1.0.1-python.org-py2.6-macosx10.3.dmg

because the file

matplotlib-1.0.1-python.org-py2.6-macosx10.3.dmg

is a disk image, which is not mounted as a directory until you do so
explicitly. MacPorts is not the right tool to install Python packages;
you need easy_install.

Everyone has to go through the Unix 101 learning curve and it's no rap
on you that you haven't yet, but until you do getting to the bottom of
why programs or packages won't install correctly is going to be a never
ending series of frustrations and getting lost.

When I figure out how to install 1.0.1, I'll update my recipe, but that
probably won't be until after I get back to actively using nltk this
fall. In the meantime, the best advice I can offer is to stay away from
the command line and use pre-fab packages like the one Denzil
recommends. You'll still need to know how to set your shell environment
variables so that the install has the correct PYTHONPATH, however.

I wish I could be more helpful.

Yes and it's recommended. I have used it myself and vouch for it.

For what it's worth, I'm having exactly the same problem -- same two
error messages (exc. for different path) -- even though matplotlib,
numpy, and nltk are in the same directory and I've imported each of
them. I did have to do a sys.path.append() to get Python to admit the
modules exist, which is a bit odd given that they're in the site-
packages for the 2.7 version that's running, and the old 2.6 version
is *not* in the path at all. --- Bill S.

I also wanted to install nltk. Actually I did this on the prebuilt Mac python
5.3 or something. I downloaded nltk modules via nltk.download() OK.
Then I tried to run: from nltk.book import *
I was getting errors right away. The stupidest thing is that I even cannot show
them.

What happened is that I read somewhere that errors might happen because the
version is not 2.6

So, I downloaded and run installation file for python2.6

I am now getting

Just seconding the suggestion: EPD does get around the problem nicely.
I had to manually move the nltk package to the directory EPD wanted,
but that took all of 2 seconds (and I probably could have avoided that
by re-installing nltk).

It also comes with it's own easy_install version. It's also really helpful while installing other packages. More so, if you use Python with an IDE like Eclipse (via PyDev plugin).

Hi everybody,

I know I havn't read the whole thread, but I had this same issue again now in 2014 and thought it was worth updating the thread.

Below is a quote from StackOverflow a found that solved all of my problems with Py 2.7 on Win 7 64-bit (ALL THE ISSUE RAISERS!!!)

Anyway, I got my 64-bit libraries et cetera from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/
and everything is working fine for me now.

"I got this problem too，than I fount I should install the dependencies first.(I use python 2.7 64bit) Here's a list of the programs you can install on windows: http://www.lfd.uci.edu/~gohlke/pythonlibs/ And you'll need the following dependencies: Requires numpy, dateutil, pytz, pyparsing, six"

Beir bua,

Currently, I would recommend using Anaconda Python Distribution. It works smoothly and has a 64-bit version as well.

Hi,

With recent pip versions numpy and matplotlib should install without a need to use compiler on OS X because there are binary wheels uploaded to pypi.

It should be possible to install them in virtualenv on Windows 64 bit too:

1. make sure pip is up to date;
2. run "pip install -f https://nipy.bic.berkeley.edu/scipy_installers numpy"

Could someone please check if this works on Windows?
