I installed cvxopt verbatim from here. On using it from the python prompt, I see the following issue:
>>> import cvxopt
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build\bdist.win32\egg\cvxopt\__init__.py", line 32, in <module>
File "build\bdist.win32\egg\cvxopt\base.py", line 7, in <module>
File "build\bdist.win32\egg\cvxopt\base.py", line 6, in __bootstrap__
ImportError: DLL load failed: The specified procedure could not be found.
>>>
Any ideas to resolve this?
cvxopt requires Numpy-MKL, you can get the windows binary here.
And install the cvxopt binary from here

I just installed anaconda and I have udpated the PATH variable.
However, I cannot run any conda related commands.
Every time I run a command starting with "conda" I get the following error.
Can anyone help?
I am using macOs High Sierra 10.13.6.

I seem to recall something similar when I first ran Anaconda on my Mac as well. I believe I solved it by doing two things:
Uninstalling Anaconda (Link)
Reinstalling Anaconda (potentially in a different location, say, under your User home)
I think in the process of installation my PATH pointed finally to a different location than the Conda/Python install.
I'm getting the following error when running import P4:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python35\lib\site-packages\P4.py", line 410, in <module>

I looked online but couldn't find something that would help.
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
I have a file test.py which contains only the line "import sdl2". I am running Ubuntu and have installed libsdl2 from the official repos and installed pysdl2 from pip3. I get this error:

My only thought is that possibly there's some version mismatch in packages? I couldn't find anything referencing this bug after a quick googling.
This is a bug in pysdl2, which indicates that your SDL2 library version is not the latest one. (2.0.3). It has been fixed in a recent commit: https://bitbucket.org/marcusva/py-sdl2/commits/03870c58615b115abf14b11056bbcd41652873c5
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
