IDLE python shell freezes after running show() of matplotlib
in [Python]
|
From: Forrest Sheng Bao on 24 Oct 2009 17:03 I am having a weird problem on IDLE. After I plot something using show () of matplotlib, the python shell prompt in IDLE just freezes that I cannot enter anything and there is no new ">>>" prompt show up. I tried ctrl - C and it didn't work. I have to restart IDLE to use it again. My system is Ubuntu Linux 9.04. I used apt-get to install IDLE.

You should really look at smart questions; I believe you have a problem, and that you have yet to imagine how to give enough information for someone else to help you. http://www.catb.org/~esr/faqs/smart-questions.html Hint: I don't know your CPU, python version, IDLE version, matplotlib version, nor do you provide a small code example that allows me to easily reproduce your problem (or not). --Scott David Daniels Scott.Daniels(a)Acm.Org
From: Donny on 27 Oct 2009 14:26 I have this problem as well. I'm on Windows XP (32-bit x86 processor) using Python 2.6.4 and matplotlib 0.99.1 (installed with matplotlib-0.99.1.win32-py2.6.exe). The IDLE version is 2.6.4. The difficulty occurs for me during the first example of the (official?) Pyplot tutorial at <http://matplotlib.sourceforge.net/users/ pyplot_tutorial.html>, so it is possible that many new users of pyplot experience this same difficulty: import matplotlib.pyplot as plt plt.plot([1,2,3]) plt.ylabel('some numbers') plt.show() I see the plot, and I can close the plot window by clicking on the X at the upper-right corner of the plot window. However, as Forrest mentioned, IDLE does not then spit out the next command prompt, nor does IDLE respond to a Ctrl-C. I have found that by turning on pyplot's 'interactive mode', the above problem does not occur: import matplotlib.pyplot as plt plt.ion() plt.plot([1,2,3]) # plot opens after this command is issued, and new command prompt appears plt.ylabel('some numbers') # if plot is not closed before issuing this command, then the open plot window is updated plt.close() # same effect as manually click-closing the plot window On Oct 24, 5:03 pm, Forrest Sheng Bao <forrest....(a)gmail.com> wrote: > I am having a weird problem on IDLE.

Look in matplotlib documentation on the difference between interactive and non-interactive modes. -- --OKB (not okblacke) Brendan Barnwell "Do not follow where the path may lead.

This is a threading issue that is very common when using gui toolkits with the interactive interpreter. You're better off just using ipython, which already has builtin support for matplotlib when you start it via "ipython -pylab" On Wed, Oct 28, 2009 at 7:41 PM, OKB (not okblacke) <brenNOSPAMbarn(a)nobrenspambarn.net> wrote: > Forrest Sheng Bao wrote: > >> I am having a weird problem on IDLE.
