IPython problem

[Seyma Ortatatli]

Dear Group,

 

I have a question concerning “IPython”. I’ve installed the “Enthought Canopy” to work with PDFgetX3. Actually the installation is successful, because I could make work the tutorials (Ni and Pt) given in the PDFgetX3 user guide with ease. The problem is when it comes to use “interactive tuning of parameters”, IPython line (ln[1], … ) sometimes allows me to write commands there (like “ ln[1]: tuneconfig()”) but most of the time it hangs out (see attached image please).

 

I do not know whether it’s because of the PC which is not that fast or is there a bug in the IPython interface. Any suggestion is highly appreciated.

 

Many thanks & have a nice weekend,

 

Seyma.

Hi Seyma,

In your example does pdfgetx3 open a plot window and then a control window with sliders after the tuneconfig() command?  

Perhaps the problem is in the choice of the GUI backend for the matplotlib plotting library, because some of them don't work very well in the interactive mode.  I'd recommend to try another backend QT4Agg.  The backend can be selected by creating a simple text file named matplotlibrc (without the ".txt" extension) in the working directory, which contains the following single line:

backend : QT4Agg

There may be more GUI backends available with Enthought Canopy, but as far as I recall, the QT4 should work fine.  If this helps, you can make the backend choice permanent by moving the matplotlibrc file to the following location (determined from IPython):

In [1]: import matplotlib
In [2]: matplotlib.get_configdir()

For more details about matplotlibrc see http://matplotlib.org/users/customizing.html.

Hope this helps,

Pavol

Hi Pavol,

 

Yes, pdfgetx3 opens a plot window and then a control window with sliders after the tuneconfig() command. But if I don’t make any operation for a second while the window is open (or not), the program hangs out. But I’m going to try now what you’ve recommended.

 

Many thanks for help..

 

Cheers,

Dear Pavol,

 

I would like to say that the software worked without any problem when I followed your suggestions. Thank you so much!!

 

Enjoy your day!

 

Regards,

Seyma.
