[Solved] Install Matplotlib

[marla06]

Hello,

 

I'm setting up my django website (http://weatherstation.heliohost.org/sitemc/charts/), but I have the problem numpy and matplotlib does not seem to be installed by default.

As matplotlib is quite a big library (about 90Mo) installing it manually might be quite difficult.

Any idea how to do that ?

 

Thanks

Looks like it requires shell access to install, which we don't provide for our users. Also, I'm not seeing alternative installation methods in the documentation.

Which version of python are you using?

#!/usr/local/bin/python2.7
Python version 2.7.1

#!/usr/local/bin/python3.2
Python version 3.2

[marla06]

I'm using Python version 2.7.1

As I did not specified any python version, I suppose it is the default.

If I want to choose a version, I suppose the line " #!/usr/local/bin/python?.? " should be at the top of my dispatch.wsgi file ?

If it is more convenient for you I can use Python version 3.2 too.

 

Cheers

Hello,

 

Have you any news about the matplotlib installation ?

 

Cordially

[Krydos]

The following were installed:

freetype 2.5.0.1
libpng 1.6.6
pyparsing 2.0.1
numpy 1.7.1
matplotlib 1.3.0

There may have been some other things installed too that I forgot to list. It seemed like every dependency had multiple uninstalled dependencies of its own.

root@stevie [/home/krydos/src/matplotlib-1.3.0]# /usr/local/bin/python2.7
Python 2.7.1 (r271:86832, May 15 2011, 21:32:40)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
>>> print matplotlib.__version__
1.3.0

It appears to be working. Apologies for the delay in getting all this set up. I've been quite busy, and as you might imagine it wasn't a particularly simple thing to install.

Apparently it only partially works. I don't have anymore the "no module present" error while I do an "import matplotlib", but get

"libpng16.so.16: cannot open shared object file: No such file or directory" instead. Maybe a problem with access rights ?

 

A minimalistic test case of what I'm trying to do (It works locally) is:

 

from matplotlib.pyplot import Figure
from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
import django
fig=Figure()
ax=fig.add_subplot(111)
canvas=FigureCanvas(fig)
response=django.http.HttpResponse(content_type='image/png')
canvas.print_png(response)

Hi,

 

Any news ? It seems we are not far from getting it to work

Hi,

 

Did you gave up ?

Please be patient. We are volunteers who help out at HelioHost on our own time.

Sorry, I was just wondering if I had to go for an other option. Glad you still looking at it.

Thanks !

I'm unable to reproduce the "libpng16.so.16: cannot open shared object file: No such file or directory" error. Can you post a link to the script that causes the error?

 

Also I'll let you in on a secret, it might seem a bit counter intuitive, but I always try to work on the topics that are the oldest first. So, when you "bump" a post it actually moves it to the bottom of my todo list each time.
