[Matplotlib-users] matplotlib upgrade 0.52->0.53.1

[Jim B. <jb...@se...>]

Hi,

  I finally tried to upgrade from matplotlib-0.52 to 0.53.1.

When i try to run my app that works fine on 0.52,
it crashes when i try to make plot (the matplotlib part).

This may not be enough info for you to help me,
but on the other hand you might immediately see something
that i have wrong. ...err is there the equivalent of 
a 'make clean" in the "python setup.py install"
(yup i'm a newbie to some aspects of python)

...i just tried a re-install of 0.52..and
while it did stuff, clearly 0.53 is still being used. 
It's my home machine...so not a real big deal. 
I also tried:

[root@floyd matplotlib-0.52]# python setup.py clean
running clean 
[root@floyd matplotlib-0.52]# python setup.py install
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/local/bin/postinstall.py to 755
running install_data
[root@floyd matplotlib-0.52]#

and

[root@floyd matplotlib-0.53.1]# python setup.py clean
running clean
removing 'build/temp.linux-i686-2.3' (and everything under it)
[root@floyd matplotlib-0.53.1]#

and then:

[root@floyd matplotlib-0.52]# python setup.py install
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/local/bin/postinstall.py to 755
running install_data
[root@floyd matplotlib-0.52]#

I also tried moving the 0.52 dist to a back, untarring and then 
redoing the "python setup.py install"

...but still i'm stuck with my non-working upgrade.  

ok..so i went into floyd:/usr/local/lib/python2.3/site-packages>
and moved the matplotlib dir to  matplotlib.bak and then tried
a re-install of 0.52...my app again words..whew! (is there an
easier way to uninstall?)

Thanks for any comments (including RT_Fine_M section xx),

Jim

The same trick should (hopefully) get 0.53.1 to work: get rid of the old 
matplotlib in site-packages before installing a new one. Probably some 
files from 0.52 are screwing up 0.53.1.

(This is a limitation of Python's distutils -- upgrades should really 
wipe the package out of site-packages rather than adding files.)

Cheers!

...and also a limitation of my late night thinking.
Your suggestion appears to have worked like a charm.
I'll definitely use your advice for all future upgrades of
any python packages.

Thanks!!

I did some testing by successively installing 0.53.1 and then my CVS
tree comparing a file in site-packages/matplotlib that I knew had
changed in the two versions.  New files do indeed replace old files,
but it appears only if their time stamps are newer.  

So if I install the 0.53.1 tree to a clean site-packages and then the
CVS tree, the file (mathtext.py) is updated (both dirs have clean
build directories).  If I then go back the 0.53.1 and flush the build
dir and reinstall, the *.so files are installed to site-packages
(these are freshly built and so have new time stamps), but the *.py
files are not, presumably because they are older than the ones in
site-packages.

I don't know why you encountered trouble Jim because you were
upgrading in the right direction (screwy system clock, something about
how and when you unarchived the different versions?) but this
definitely explains why your attempt to downgrade failed.

But Andrew is definitely right: when in doubt I do

  > sudo rm -rf /usr/local/lib/python2.3/site-packages/matplotlib
  > sudo rm -rf build

before installing.

I checked distutils and there does not seem to be any flag you can set
to guarantee a clean install.
