could you also release a tarball on SF, so I can start updating the
debian package and give it a spin on our distro?

[Benjamin Root]

Hmm, that should work. I notice that you are using the beta 3.0 ipython
release. Perhaps something is broken in the beta? Could you try downgrading
ipython (and the notebook server, they are separate packages, I think)?

Sure I can, but since all the previous release (even RC) were done one
SF, we have our tools to monitor and download new releases pointing to
SF: do you plan to switch to GH for releasing tarballs too?

[Thomas Caswell]

Yes, I think that if you want to use ipython 3.0 you need to use mpl 1.4.3
or master.

 I start the notebook with :

 I've tried this both inside and out of a virtualenv  virtual

 hi Benjamin

 This sequence in a new notebook:

 %matplotlib nbagg
 import matplotlib as mpl
 import matplotlib.pyplot as plt
 plt.plot(range(100))

 also results in exactly the same result - the figure placeholder (not
 sure what the exact term is) but no figure inside it.

 Regards.

 Selecting a backend must be first before any other matplotlib actions.
 Typically, ipython magics (the %matplotlib commands) are kept at the top
 anyway.
 I hope that clears it up.

 Hello,

 IPython 3.0.0-b1
 matplotlib '1.4.2'
 The version of the notebook server is 3.0.0-b1-ee6223a.

 I set up matplotlib as follows:

 %matplotlib nbagg


 Then running this command:

 only displays a box (with resize, zoom, pan, etc controls)  - but does
 not
 show the figure itself (see figure).
 
 Also, when I click on any part of the figure, I get a slew of the
 following
 message on stderr:

 On the other hand,

 shows nothing at all.

 However, this

 What is going on ? How can I enable the new notebook backend for
 matplotlib
 ?

 Thanks.

Sandro,

Well, creating the tarball on GH is a lot easier for us as it happens
automatically!  I don't want to unilaterally change policy so I will create
the files on SF.

If you want to tracking GH for debian instead of SF I don't think that
would be a bad idea, but I don't know how much of a hassle that would be
for you.

Upgrading matlplotlib to the git head version  worked perfectly.
Thanks !

Yes, I think that if you want to use ipython 3.0 you need to use mpl 1.4.3 or 
master.

Hmm, that should work. I notice that you are using the beta 3.0 ipython

ipython (and the notebook server, they are separate packages, I think)?

The squares in the first test are larger than they should be. I have some
other errors, but they seem to other be floating point errors, or issues
with fonts.
