I've been following this guide. Unfortunately I don't think llvmpy is being installed properly (here is the output from python).
>>> import numba

Doing python -c "import llvm" gives me the same error as above ("No module named _capsule"). Any ideas? I am not getting errors while installing llvm,llvmpy or numba, but it is pretty clear that llvmpy isn't getting installed properly
I forgot to answer this. I solved the problem as the underlying issue was an Apple-release (see this answer to a similar'ish question).
TLDR:
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
And then follow the guide given here

I can't figure out why jupyter-lab is not working. something is broken and don't know where. I have searched the web for this and can't find a solution. COuld you please help. Appreciate it.

You need to install the dateutil library: https://pypi.python.org/pypi/python-dateutil/
(If you used a package manager, the dependencies for JupyterLab should already have been installed. If you didn't, then you will need to install the dependencies yourself.)

Since then the only change I have made is to install the macOS Supplemental Update and to upgrade Python from 2.7.13_1 to 2.7.14_2 (using Homebrew). I have changed the relevant linker flags in the makefile, i.e. those that appear when I type python-config --ldflags. I have also made sure that the Python I am using is definitely the Homebrew one by inserting export PATH="/usr/local/opt/python/libexec/bin:$PATH" into my .bash_profile as directed by Homebrew.
I am not sure whether this error is because of the Python update, the recent macOS Supplemental Update, or something else. Any idea what the problem could be?
Thanks
I had the same problem;
In python 2.7 the NumPy 1.8.0 was available,
Then I installed NumPy (again) using brew, and it wasn't available in my python (2.7) anymore. (Got the same error you got here)
So I did "brew unlink python && brew link python" to use python 3 (instead of 2) which NumPy 1.14 is available in it.
I guess the python 2.7 was not compatible with this recent version of NumPy.
I am really new to python and I am trying to install the statsmodels module. It seems that since I am on a 64 bits I need to use the following unofficial website http://www.lfd.uci.edu/ I did all I know about how to download a whl and I did download it and used the pip afterwards and all work fine. now when I do pip install statsmodels it work fine. However, in my shell after I try import the stats models I am getting
import statsmodels

Any help would be much appreciated.
Thank you in advance
Ok, I'm using python 3.3. I have numpy, llvm, llvmpy, llpyhton, llvm_array, llvm_cbuilder and llvmath installed. I have also installed numba.
However, when trying to import via import numba, the following error appears. I have no idea of what could be missing:

Any ideas?
Ok, I found out what was wrong.
I added the anaconda folders to the deafault python3 interpreter, instead of installing numba directly in the packages folder.
I have python 2.4 installed on an ARM processor and have moved all of the libraries I need onto this machine including those for numpy 1.6.2 When I try to import numpy, I get the following:
>>> import numpy

When I try to see if the file exists I get:
# ls /usr/lib/python2.4/site-packages/numpy/core/ | grep multi
multiarray.so
I'm pretty new to python in general and don't know why I'm getting this error. Any suggestions?
this is indeed the first error you have when you are trying to import numpy with binaries for the wrong architecture.
