Import Error help me!

[Weisong Zhou]

I download the Anaconda3-5.0.1-Windows-x86_64.exe and my pc installed win10 64-bit

I just type import numpy as np, but it doesn't work.

Most likely you are trying to import a failed build of numpy. If you're working with a numpy git repo, try `git clean -xdf` (removes all files not under version control). Otherwise reinstall numpy. Original error was: cannot import name 'multiarray'

What output do you see if you open the Anaconda prompt from the Start menu and then run these commands?

conda update numpy

python

import numpy as np

I got the same error

It looks like this may be caused by a bad interaction between NumPy and the Intel MKL libraries. Would you please file an Anaconda bug report here? https://github.com/ContinuumIO/anaconda-issues/issues

Searching on Google for [numpy multiarray] turned up discussions of similar problems, including https://github.com/numpy/numpy/issues/9272 and some items in the anaconda-issues repository.

Hi Team,

I resolved the issue with the below steps:

1. My local numpy version was 1.4.5 but anaconda version was 1.4.0. 

2. I tryed "conda install numpy=1.4.5" - but because of previous traces it did not work.

3. I uninstalledmy local numpy (Important step)

4. Uninstalled and deleted the entire anaconda folder.(Important step)

5. Reinstalled anaconda = Everything worked fine

Thanks,

Kunal
