qtconsole

I'm plotting some large plots in IPython QtConsole (and Notebook). These take up a lot of memory, but once they are plotted I don't need them any more and they can go. How can I free up memory? None of the following works: close() clf() cla() %reset The only thing that frees the memory is restarting the kernel , which I don't always want to do (say I worked through a long process to get to a specific point) [To be precise, %reset does free up some memory, but not as much as restarting the kernel]. How to replicate the problem: plot(arange(2e7)) You may need a bigger or a smaller number to

I have python 3.4 and ipython 2.3.1 installed on Windows 7. I installed ipython using pip from a wheel from http://www.lfd.uci.edu/~gohlke/pythonlibs/ (Thanks, Chris!). This install procedure does not create any start menu shortcuts, even when run as administrator. I can successfully run "ipython qtconsole" from a cmd window, but then I have to have that command window open and the process doesn't fork--it's just and extra window hosting the child process. If I create a shortcut to do the same, it opens a cmd window which then opens the qtconsole. So, how do I start qtconsole without having an

I need some advise here. I've installed ipython (sudo pip install ipython[all]) I've python 2.7, mac osx 10.9 64bits.

I have ipython with qtconsole installed and can start it via ipython qtconsole . I can also run a script via ipython -i my_script.py to stay in the interactive interpreter after the script finishes or if an exception is thrown. But I could not figure out how to combine them: I would like to do ipython -i qtconsole my_script.py but whatever I try, it complains about invalid flags. Any hint how to do that? Greg Interesting, it seems that either this option was forgotten or not wanted in the qtconsole. A way around this (or perhaps an intended way?) is to use the -m flag. This runs a module as a

I recently upgraded my version of pandas. I have the latest stable version installed now: pd.__version__ Out[5]: '0.10.1' prior to this upgrade, this is how dataframes were displayed in the qtconsole shell (this isn't my screenshot but simply one i found on the web). The latest version of pandas also uses a different approach to setting the display options. Rather than using pd.set_printoptions , pandas wants you to use the set_option configs like this: pd.set_option('display.notebook_repr_html', True) After upgrading my pandas version, qtconsole no longer renders dataframes as html tables. An

I have a PyQt program that is displaying some widgets and buttons. I want the program to run either as a standalone python instance, or inside an ipython environment. In this case, I use the following magic command in Jupyter console (formerly I had to use --gui=qt when launching the ipython qtconsole) %pylab qt In order to have a program that works both ways, my main module has the following lines: APP = QtGui.Qapplication.instance() # retrieves the ipython qt application if any if APP is None: APP = QtGui.QApplication(["foo"]) # create one if standalone execution if __name__=='__main__': APP
