Re: [Numpy-discussion] Using numpy on hadoop streaming: ImportError: cannot import name multiarray

Thanks David. But do I need to install virtualenv on every node in hadoop cluster? Actually I am not very sure whether same namenodes are assigned for my every hadoop job. So how shall I proceed on such scenario. Thanks for your inputs. Kartik On Feb 11, 2015 1:56 AM, "Daπid" wrote: > On 11 Febr

[Numpy-discussion] Using numpy on hadoop streaming: ImportError: cannot import name multiarray

Hi all, for one of my projects I am using basically using NLTK for pos tagging, which internally uses a 'english.pickle' file. I managed to package the nltk library with these pickle files to make them available to mapper and reducer for hadoop streaming job using -file option. However, when nltk

[Numpy-discussion] Matrix Class

It seems to be agreed that there are weaknesses in the existing Numpy Matrix Class. Some problems are illustrated below. I'll try to put some suggestions over the coming weeks and would appreciate comments. Colin W. Test Script: if __name__ == '__main__': a= mat([4, 5, 6])

[Numpy-discussion] How to debugging python crash in ipython notebook

Hello all, I am struggling with a python crash of an ipython notebook (kernel) that I do not know how to debug. If I run this: (valgt is a pandas dataframe with 354 lines and 14 numerical columns) sns.pairplot(valgt) plt.savefig('parvis.png', dpi=600) in the same cell, the kernel consistently

Hello, I apologize for pinging the list, but I was wondering if there was interest in either of https://github.com/numpy/numpy/pull/5457 (make array data aligned by default) or https://github.com/numpy/numpy/pull/5470 (make the array data allocator configurable)? Regards Antoine.
