Google OR-Tools Installation Windows 10 - Python 2.7 64bit

[Jonathan]

Hi everyone,

I am trying to install Google OR-Tools on a Windows machine with Python 2.7 (for convenience as the example are written in 2.7).

Could you provide some .exe files ?

I've tried installing it using the binary without success make install: doesn't exist 

I've tried installing it using the source files. I am getting the following error:makesfiles/Makefile.port:130: "Unrecognized visual studio version"... (see picture)

I was using the Developer Command Prompt for VS 2017.

Thanks in advance for your help,

Jonathan

I am trying to install or-tools-6.0 (downloaded from https://github.com/google/or-tools/archive/v6.0.zip) 

[Laurent Perron]

To install binary archives for python, 

download the example file: (v6.2)

https://github.com/google/or-tools/releases/download/v6.2/or-tools_python_examples_v6.2.4388.zip

unzip, cd in the directory

<path to python2.7>/python.exe setup.py install

it should install at least 2 packages: protobuf, and ortools

to install from sources, you need to use make in or-tools\tools\make.exe

usually, in or-tools, type tools\make third_party, followed by tools\make python

You can test with tools\make test_python.

I hope this helps

PS: We will improve the doc.

Hi, 

my command prompt is the no developer command prompt for vs 2017, but the x64 native tools command prompt for vs 2017

can you try with that?

OK, let's make sure all assumptions are correct.

You are using 64 bit python on a 64 bit windows?

[Jonathan]

I'v also tried using x64 native tools command prompt for VS 2017. I am getting the same error.

[Jonathan]

Yes.

I've also tried to install from \or-tools-6.0\or-tools-6.0\tools by :

1) cd in \or-tools-6.0\or-tools-6.0\tools

2) C:\Python27\python.exe setup.py install 

3) Getting error :

 File "setup.py", line 25

    DELETEUNIX               extra_link_args=['/MANIFEST'],

                                           ^

SyntaxError: invalid syntax

In addition line 72: read('README.txt') won't work as the file is not in the directory.

[Jonathan]

I finally used https://pypi.python.org/pypi/ortools/5.1.4045 executable (.exe). It is not the last version but at least it allows a quick install :)

[Laurent Perron]

We do provide .exe files:

https://pypi.python.org/pypi?:action=display&name=ortools&version=6.3.4431

Can you try this one?

Hello, I've tried the installation of OR-Tools using the executable and also the make files without luck. I'm using Windows 10 and Microsoft Edge.

Any suggestions to install OR-Tools with Python 2.7?

[Laurent Perron]

I need more info :-)

32 bit or 64 bit, which version, what is the error message?

Thanks

(ok, 64 bit is in the title).

still, what is the error message?

Are you sure you installed 64 bit python?

This is a hunch on my part, but the latest NuGet package was also built for 32-bit, not 64-bit; I get image related errors about it. Could be related. I've been using the version prior to that.

[Laurent Perron]

I have not 32 bit build anywhere, are you sure of that?

Positive. I had to roll back to the previous version.
