Question

I updated my Python through Conda and now I get this error. I had no problem before with Anaconda Python. What are some quick/easy fixes?

Monas-MacBook-Pro:P3 mona$ python k_means_clustering.py 
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

ImportError: 
Importing the multiarray numpy extension module failed.  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.

Answer 1

Not sure why would that have happened after updating to Python 3.6.2 from Python 3.5.4 but this solved the issue for me.

Monas-MacBook-Pro:P3 mona$ conda install -c conda-forge openblas=0.2.19
Fetching package metadata .............
Solving package specifications: .

Package plan for installation in environment /Users/mona/anaconda:

The following packages will be UPDATED:

    openblas:  0.2.19-1              --> 0.2.19-2                      conda-forge
    scipy:     0.19.1-py36h3e758e1_3 --> 0.19.1-py36_blas_openblas_202 conda-forge [blas_openblas]

The following packages will be SUPERSEDED by a higher-priority channel:

    conda:     4.3.27-py36hb556a21_0 --> 4.3.27-py36_0                 conda-forge
    conda-env: 2.6.0-h36134e3_0      --> 2.6.0-0                       conda-forge
