An item extracted from an array, e.g. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information.

u = u + alpha*p is the line of code that fails. I have a 2000 by 1,000,000 matrix A and want to calculate the 2000 by 2000 matrix .> B = numpy.dot(A,A.T) but numpy just eats up all my memory, slows down my whole computer and crashes after a couple of hours.

Bref si quelqu'un à une idée. When I run import numpy as np a = np.ones((400, 500000), dtype=np.float32) c = np.dot(a, a.T) produces a "MemoryError" on the 32-bit Enthought Python Distribution on 32-bit Vista. I understand this has to do with the 2GB limit with 32-bit python and the fact numpy wants a contiguous chunk of memory for an array.

EDIT: Je n'avais pas précisé mais j'utilise Python 2.7 et numpy 1.6.1 Processing large NumPy arrays with memory mapping.

This is one of the 100+ free recipes of the IPython Cookbook, Second Edition, by Cyrille Rossant, a guide to numerical computing and data science in the Jupyter Notebook.The ebook and printed book are available for purchase at Packt Publishing.

EDIT: Je n'avais pas précisé mais j'utilise Python 2.7 et numpy 1.6.1 If working outside ArcGIS Desktop on 64-bit OS, use a 64-bit Python as an alternative environment for OSGeo processing--the GDAL libraries and NumPy in this … xtensor: Multi-dimensional arrays with broadcasting and lazy computing for numerical analysis. The specific maximum memory allocation limit varies and depends on your system, but it’s usually around 2 GB and certainly no more than 4 GB. Thanks python memory numpy scipy | You can follow the question or vote as helpful, but you cannot reply to this thread.

32-bit Python is not compiled LargeAddressAware, meaning it will only be able to address 2GB of user addressable memory space per process thread running on either 32-bit or 64-bit Windows.
