Python matplotlib library install in max os x -


I am trying to install the matplotlib library for Python. The establishment was okay, but when I imported Yellowbank (such as Import Yellowab P) in Pythab, I got the following error. 

  file "/ library / frames / python framework / version / 2.7 / lib / python2.7 / site-packages / matplotlib / mathtext.py", line 61, & lt ; Module & gt; dlopen (/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/_png.so, 2): As _png ImportError did not import matplotlib._png symbol referred to _png_set_longjmp_fn expected /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/_png.so: flat name /Library/Frameworks/Python.framework/Versions/2.7/lib/python2 Location. 7 / site-packages / matplotlib / _png.so   
 
 Google searches indicate that the link error (which does not appear for "_png_set_longjmp_fn") 32/64 Bit Compiling Issue for PGG Library  
 I tried to re-install matplotlib based on the README.osx file in the library, but it was not decided. I found that it was not resolved in other ways. Apart from this, I have checked that the libraries have been compiled on 32 or 64 bit. Both related binary support (universal binaries) as follows.

 My OS X version tiger is 10.7.4. Do you have any idea about this problem? Thanks!   
 
 
 I had the same problem when I did the second day from  Matplotlib import pattern  Five hours after closing my head against the wall the other day, this solution worked for me ( 
 I got this set of commands to set up symlinks:  
 < Code> sudo mkdir -p / usr / local / sudo ln -s / usr / x11 / include / freetype2 / freetype / usr / local / include / freetype sudo ln -s /usr/X11/include/ft2build.h / usr / Includes local / include / ft2build. H Sudo LN-S / USR / X11 / includes / png.h / usr / loc Al / include / png.h sudo ln -s /usr/X11/include/pngconf.h/usr/local/include/pngconf.h sudo ln -s /usr/X11/include/pnglibconf.h/ usr / local / include / pnglibconf.h sudo mkdir -p / usr / local / lib sudo ln -s /usr/X11/lib/libfreetype.dylib / usr /local/lib/libfreetype.dylib sudo ln -s / usr / X11 / lib / Libpng.dylib /usr/local/lib/libpng.dylib   
 It does not solve all of your issues, but it is my PKG-config problem (among others) Has solved. Perhaps a similar link will help with QT.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
