I'm trying to learn Machine Learning, but I cannot resolve below error.
[My environment]
- Mac High Sierra 10.13.2
- Python3.4.5
- Numpy1.13.3
[Command]
$ python3 -c "import jupyter, matplotlib, numpy, pandas, scipy, sklearn"
[Error]
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb

ImportError: C extension: numpy.core.multiarray failed to import not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace --force' to build the C extensions first.
[Things I tried]
I understood numpy is wrong. So I tried below things, but the error still appears.
~1~
sudo mv /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy_old
~2~
pip3 uninstall numpy
pip3 install numpy -I
Thanks.
Seems like this is due to pandas version higher than 0.21.0 and numpy
version 1.13.3 that is pulled by TensorFlow not playing well togather.
Here is how I fixed it in my end:

Most likely due to version of numpy too low; this one solved my problem:
pip3 install "numpy == 1.15.0" --user
conda install can't solve because currently it only have numpy version 1.13.1, but is may due to my mirror site choosen is not the latest
I had same issue. If you are using anaconda simply type
conda update tensorflow
This should fix the issue.
Base on currently installed tensorflow or sklearn packages, there might be some incompatibility. You should try different numpy version. BTW, in my case, downgrading from 1.18 to 1.15 fixed the problem.
pip install "numpy == 1.15.0"
