Installing NumPy via Anaconda in Windows

Question

I am trying to use Numpy in a Python 2 7 8 script in Windows  So  I download and installed the latest version of Anaconda  I also want to use some of the other tools in Anaconda  to the directory  C  Anaconda   As default  I checked the boxing asking me if I wanted to add the path to the binary files to the Windows PATH   After checking PATH  it contains the following   C  Anaconda C  Anaconda Scripts    Then  after installation I open a new Command Prompt  and in the Python envirnoment  I enter  import numpy   but this gives the error   ImportError  No module named numpy    What stage have I missed out in the installation process         EDIT        I have just noticed that there is no file called  numpy  in either  C  Anaconda  or  C  Anaconda Scripts   But according to the Anaconda website  http   docs continuum io anaconda pkg-docs html   the installation should come with Numpy           EDIT        It seems that Windows was running Python from an existing version of Python I had installed  which was not associated with NumPy  After deleting this  and running Python from the Anaconda installation  NumPy is now being recognised

I had the same problem  getting the message  ImportError  No module named numpy    I m also using anaconda and found out that I needed to add numpy to the ENV I was using  You can check the packages you have in your environment with the command      conda list   So  when I used that command  numpy was not displayed  If that is your case  you just have to add it  with the command      conda install numpy   After I did that  the error with the import numpy was gone

Yep you should start anaconda s python in order to use python libs which come with anaconda  Or otherwise you have to manually add anaconda lib to pythonpath which is less trivial  You can start anaconda s python by a full path   path to anaconda python exe   or you can run the following two commands as an admin in cmd to make windows pipe every  py file to anaconda s python   assoc  py Python File ftype Python File C  path to Anaconda python exe   1       after this you ll be able just to call python scripts without specifying the python executable at all

The above answers seem to resolve the issue  If it doesn t  then you may also try to update conda using the following command   conda update conda   And then try to install numpy using   conda install numpy
