问题 This is a more general question about how to run "embarassingly paralllel" problems with python "schedulers" in a science environment. I have a code that is a Python/Cython/C hybrid (for this example I'm using github.com/tardis-sn/tardis .. but I have more such problems for other codes) that is internally OpenMP parallalized. It provides a single function that takes a parameter dictionary and evaluates to an object within a few hundred seconds running on ~8 cores ( result=fun(paramset,

问题 I want to add some css to part of my plot, (specifically, I want to set float:left ). How can I produce the plot within a div, so I can use css to control its layout? For example, for code def simple_plot(ax = None): if ax is None: fig, ax = plt.subplots() a = [1,2,3,4] b = [3,4,5,6] plt.plot(a, b,'-', color='black') simple_plot() The default output html in Ipython Notebook is <div class="output_area"> <div class="prompt"></div> <div class="output_subarea output_png"> <img src="data:image/png

问题 My ipython was working fine until I installed a new IDE and accidentally changed some path settings. Now, when I try to launch ipython from terminal I get: -bash: /Users/JohnSmith/anaconda/bin/ipython: /Users/JohnSmith/anaconda/python.app/Contents/MacOS/python: bad interpreter: No such file or directory How do I change my path/local environment settings back so that it works? 回答1: It seems that uninstalling and re-installing Anaconda was the easiest solution (after several hours of playing

问题 Is there any way to control which namespace you end up in after an unhandled exception? For example, if I'm at an ipython prompt and I go run blah.py on a file with these contents: def spam(): ham = 'ham' crash = 1/0 eggs = 'eggs' if __name__ == '__main__': foo = 'foo' spam() it crashes out obviously but returns me to an ipython prompt, with foo now in the namespace (and any previously existing foo is now overwritten with 'foo' ). But no ham . For some post mortem inspection, it is often the

问题 I have a pandas dataframe with three columns: Name Name2 DateTime 2016-06-10 05:22 2016-06-10 05:23 2016-06-10 14:25 Guest Guest1 2016-06-10 15:32 I have to replace empty spaces with NAN. So AccountName and AccountName2 of rows 1,2,3 and 4 should be NAN. I tried the below statement: df3['Name'] = df3['Name'].replace(r'[^\s+]',np.nan, regex=True) But since I have white spaces after "Guest " in Name, all 5 rows get replaced with NAN. Edit: This is our actual data. Name Name2 DateTime \t\t-\r\n

问题 When trying to load Cython extension from my Jupiter notebook %load_ext Cython I get the below message: The Cython module is not an IPython extension I did not have this problem a couple of weeks ago, when I wrote a Cython extension on my nb. I have tried to upgrade ipython and cython both from my regular environment (I am using a Mac running 10.11) and from Anaconda, with no success. Any tips? Thanks a lot! 回答1: Cython is not an IPython extension, so %load_ext won't work on it. You can still
