Installing SIP for Python 2.7 on windows 10

I have seen many threads that have a high level of ambiguity and go off on tangents from the original question, often assuming much about the authors ability, so I am hoping that if I am direct and concise with my information, I will get an answer that is in line with the requirement. I know that the serious programmers will have seen this many times, in many formats, so please just bear with me as this is doing my head in. Please do not just post a link to some other answer as I rarely find that helps with my current issue.
I am not a hardcore programmer, I find the compiling, sourceball, tar, gz all nonsense to be honest and am looking for the easiest way to install sip for python on my machine. I have installed various versions of mingw32, mingw64 to the point that I don't know which one is best to use. I am assuming that the one here: C:\Program Files\mingw-w64 is the one, considering I am using 64 bit, but do the others I have installed impact on this?
I also installed versions of mysys:
C:\msys\1.0,
C:\msys64, but I still m unclear what and why etc, despite trying to read the docs that came with them.
I have windows 10, 64 bit professional edition.
I have python 2.7
I have installs of mingw, 32 bit and 64 bit in various locations, due mostly to not fully understanding what exactly it was or where it should go. I found zips of it and exes, so I got a bit confused.
I downloaded the sip package and unpacked it to here: C:\Python27\Lib\site-packages\sip-4.19.3 and it has the configure.py file in it. So far, so good.
I used a CMD window, changed directory to: C:\Python27\Lib\site-packages\sip-4.19.3 and then used the command: python configure.py to create the Makefile file which is what I believe is supposed to happen.
I then opened the mingw64 shell, changed directory to the above sip folder and typed: python configure.py again, just to be sure I would get a response and create the files again, probably should not have done so, but hey ho, at this point, I am quite frustrated with it and trying to do anything with what I have, which I know is poor practice. (see image 1.)
image 1: configure.py executed
From what I have read, I should use the make function that comes with Mingw64, but I tried the following, which also includes the configure.py code, but nothing seems to work when trying to use the Makefile file that was created via the configure.py process.
c:\Python27>cd ./Lib/site-packages/sip-4.19.3
c:\Python27\Lib\site-packages\sip-4.19.3> python configure.py
This is SIP 4.19.3 for Python 2.7.13 on win32.
The SIP code generator will be installed in C:\Python27.
The sip module will be installed in C:\Python27\Lib\site-packages.
The sip.pyi stub file will be installed in C:\Python27\Lib\site-packages.
The sip.h header file will be installed in C:\Python27\include.
The default directory to install .sip files in is C:\Python27\sip.

So now I am at an impasse. I have the locations of my mingw versions and the msys in my path environment variable and I have done just about everything I have looked at on the web. I realise that its an order of things, but I really wish there were just executables for these modules and supporting tools as this compiling is a ball ache.I tried opening a python shell and importing sip.
>>> import os, sys
>>> import sip
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
import sip
ImportError: No module named sip
>>> import sipconfig
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
import sipconfig
ImportError: No module named sipconfig
>>> from sip import sip
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
from sip import sip
ImportError: No module named sip
>>> from sipconfig impport sip
SyntaxError: invalid syntax
>>> from sip import *
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
from sip import *
ImportError: No module named sip
So, if anyone has read through this and has a definitive answer as to what I am doing wrong, I would appreciate it.

make/nmake or make/nmake install cant be done from cmd and python path; instead using mingw or visual studio tools.
In windows search for prompt or Visual studio tools to open VS Command promt and from there cd--> sip file location (before this run configure.py present in sip folder)
Now run the commands nmake and then nmake install

Install SCIP solver on Python3.5 Numberjack (OSX)

I am learning Constraint Programming in Python and, for the solving of the problems, I am supposed to use the SCIP solver. I have installed the Numberjack standard package from Github witch includes Mistral, Mistral2, Toulbar2, MipWrapper, SatWrapper, MiniSat and Walksat solvers.
Running my code I got the following error:
Traceback (most recent call last):
File "/Users/angelocoelho/anaconda3/lib/python3.5/site-packages/Numberjack/__init__.py", line 910, in load
lib = __import__(solverstring, fromlist=[solverspkg])
ImportError: No module named 'Numberjack.solvers.SCIP'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "grafosdefluxos.py", line 42, in <module>
solver = model.load('SCIP')
File "/Users/angelocoelho/anaconda3/lib/python3.5/site-packages/Numberjack/__init__.py", line 915, in load
solvername)
ImportError: ERROR: Failed during import, wrong module name? (SCIP)
I already ran make in 'scipoptsuite-3.1.0' and in 'scip-3.2.1', installed Numberjack-master's 'setup.py' and tried this:
python setup.py -solver SCIP
witch returned the error
Error: the solver 'SCIP' is not known, please use one of: Mistral, SatWrapper, Toulbar2, Walksat, MipWrapper, MiniSat, Mistral2
I have the SCIP folders alongside and inside the Numberjack folders.
I read and ran all the commands in the README and INSTALL files on how I could get this solver configured but I couldn't get it right.
How can I get SCIP available to solve the problems in Numberjack?

After talking to the assistant teacher I got the answer for this problem.
The folder where Numberjack/SCIP was being installed was not the one it was supposed to be, therefore it was not really included in the solver list. After completing the python setup.py build and python setup.py install installation I ran python setup.py build -solver SCIP and the terminal feedback stated
Successfully built solver interfaces for MipWrapper, SCIP
But the jupyter notebook didn't recognize the solver.
What solution should work having Anaconda (python3.5) already installed:
Download Numberjack (file "Numberjack-master.zip") and unpack it.
Download SCIP and copy the downloaded file, scipoptsuite-3.1.0.tgz. Paste it inside Numberjack-master unpacked directory. The path of it should be ~/Downloads/Numberjack-master/scipoptsuite-3.1.0.tgz.
In terminal run cd ~/Downloads/Numberjack-master (or your Numberjack-master directory path).
Then run python3.5 setup.py install --user.
In my case Jupyter was looking for the solvers in
~/anaconda3/lib/python3.5/site-packages/Numberjack/ and they were
not being installed there so, instead of using python, I used python3.5 since my Anaconda was the Python 3.5 package.

Why is there a scip-3.2.1 directory? The SCIP Opt Suite 3.1.0 contains SCIP 3.1.0. You need to make sure to run all setup and make commands exactly as stated on the Numberjack install page.

Error installing pyflycapture2 on Windows

I am attempting to install this https://github.com/jordens/pyflycapture2 python binding on my Windows machine. The readme only has instructions on how to do it for Linux systems, but I imagine the library should still work.
I am able to run "python setup.py install" and it seems to successfully complete, but when I try to run "python test_flycapture2.py" I get this error:
C:\Users\clinic\Desktop\pyflycapture2>python test_flycapture2.py Traceback (most recent call last):
File "test_flycapture2.py", line 20, in <module>
import flycapture2 as fc2
File "build\bdist.win-amd64\egg\flycapture2.py", line 7, in <module>
File "build\bdist.win-amd64\egg\flycapture2.py", line 6, in __bootstrap__
ImportError: DLL load failed: The specified module could not be found.
This seems to imply that flycapture2 wasn't installed correctly. When I instead just open a python session and do "import flycapture2" I get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build\bdist.win-amd64\egg\flycapture2.py", line 7, in <module>
File "build\bdist.win-amd64\egg\flycapture2.py", line 6, in __bootstrap__
ImportError: DLL load failed: The specified module could not be found.
Have I done something wrong with the installation process or does pyflycapture2 just not work with Windows?

A dumb solution that's worth a try. There are chances that the DLL are searched directly from where you're starting the python script. So if you have the dll somewhere on your computer, copy it along where you have your test_flycapture2.py.
But given the fact that the setup.py file has a whole bunch of absolute paths in there, I would not place my hopes too high. You can also try to install FlyCapture 2 at the exact same path, run python setup.py bdist_wheel (you will need to install wheel first with pip) in the pyflycapture2 folder, and see if that succeeds.
If it does, try installing the generated wheel (that will be in dist/ subfolder) by doing pip install dist/pyfly....wheel and test again.
Hope this helps

I'm answering this mostly because I found another post where the same question had been posted but the original problem was never answered.
How do I run an installed Python module on Windows?
In the comments, the original poster says that it suddenly started working. I found that the solution was simply to restart my computer. I have now attempted this on two computers and this worked for both of them.

Difficulties installing SOAPpy module

I am very new to python and have been figuring out how to install modules.I have been trying to install the SOAPpy module and have only had success with the required modules fpconst, wstools, and setuptools(not mentioned as required, but still ended up being required).
I am getting an error when I try and install the SOAPpy module.
Traceback <most recent call last>:
File "...\setup.py", line 43, in module <module>
__version__ = load_version()
File "...\setup.py", line 35 in load_version
execfile(filename, d.__dict__)
IOError: [Errno 2] Unable to load the version number (no such file or directory):
'...\\src\\SOAPpy\\version.py'
Not sure what i should do to fix this.
Any help is greatly appreciated!

Looking at SOAPpy's setup.py file, it tries to import SOAPpy.version. This doesn't work if you're calling it from somewhere else. Try running it directly in the SOAPpy directory because Python adds your current working directory to sys.path. For example:
cd C:\Users\eclaird\Download\SOAPpy\ # The folder with setup.py
python.exe setup.py install

Thanks for the help.
I eventually found what the issue was. I had to get some other required modules for the install to work, also the tar file I got was missing directories, so I found the completed version on Github.

Python bindings for libtorrent-rasterbar are not working

I'm running Debian 6.0.6
I've downloaded latest version of libtorrent-rasterbar from here: http://code.google.com/p/libtorrent/downloads/detail?name=libtorrent-rasterbar-0.16.6.tar.gz&can=2 and installed it:
./configure --enable-python-binding
make
make install
cd bindings/python
python setup.py build
python setup.py install
now I want to test whether the library works:
>>> import libtorrent
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: libtorrent-rasterbar.so.7: cannot open shared object file: No such file or directory
The packaged version of libtorrent from the distributive's repository had some funny behaviour (complaining on boost dependences), so I've decided to upgrade. The same situation is on both of my debian boxes, yet ubuntu box is fine.
old error message from my debian box:
File "ar.py", line 15, in create
s.start_dht()
Boost.Python.ArgumentError: Python argument types in
session.start_dht(session)
did not match C++ signature:
start_dht(libtorrent::session {lvalue}, libtorrent::entry)

Search for the shared object file and add it to your path.
sudo updatedb
locate libtorrent-rasterbar.so.7
This should output /<path_to_directory>/libtorrent-rasterbar.so.7
Add this to your ~/.profile or temporarily tell Python where to look:
export LD_LIBRARY_PATH=/<path_to_directory>/
