I have problem with installation of qutip under windows with xypython

[stephan...@gmail.com]

1. Install the Python(X,Y) distribution (tested with version 2.7.3.1). Other Python distributions, such as Enthought

Python Distribution or Anaconda CE have also been reported to work.

2. When installing Python(x,y), explicitly select to include the Cython package in the installation. This package

is not selected by default.

3. Add the following content to the file C:/Python27/Lib/distutils/distutils.cfg (or create the file if it does not

already exists):

[build]

compiler = mingw32

[build_ext]

compiler = mingw32

The directory where the distutils.cfg file should be placed might be different if you have installed the Python

environment in a different location than in the example above.

4. Obtain the QuTiP source code and installed it following the instructions given above.

I follow this procedure but I think that something is missing...

Thanks for helping

Can you tell us exactly what error you are getting?  Also, it is now best to use the Anaconda package when running under Windows.

Hi Paul,

I have a problem with the link at the end of the procedure.

this the error message

ImportError: Building module qutip.cy.sparse_utils failed: ["LinkError: command

'gcc' failed with exit status 1\n"] 

I am under  windows seven 64 bits.

I use 2.7.3.1 version of pythonxy.

I am ready to use Anaconda instead but I see "Anaconda might work too" and I don't see any procedure

under this link.

http://qutip.org/docs/2.2.0/installation.html

Thanks,

Stéphane

[stephan...@gmail.com]

I have also verified that MinGW32-xy is in the path (env. variables)

Note

[Paul Nation]

It seems that the gcc cannot be found even though mingw32 is on your path.  Quite strange,  but I also had issues with building the cython files under pythonxy. My suggestion would be to use the Anaconda package instead. We have checked that that works. Once installed,  you can install qutip via the usual

Python setup.py install

Since we do not develop qutip on Windows,  it is hard to be more specific then this.

Thank you.

I am going to try with Anaconda. Is it roughly the same procedure ?

[Paul Nation]

Should be simpler. Just install Anaconda and then install qutip.

[Stéphane Le Bec]

Ok. With pip for example ?

[Stéphane Le Bec]

with the command "conda install qutip" it does not work (no package found)

I tried "conda install C:\Python\QutiP-2.2.0.tar.gz" no more success ...(no package found)

[jrjoh...@gmail.com]

Hi

We don't have pre-build conda packages for qutip on windows, but if you want to build a conda package for qutip you can get the recipe from

https://github.com/conda/conda-recipes/qutip

or you can install qutip using pip (but don't use the --install-option=--with-f90mc option on windows).

Note that even if you use anaconda, you still need to edit the distutils.cfg file (which in that case should be the one distributed with anaconda) and add the section:

[build_ext]

compiler = mingw32

[Stéphane Le Bec]

Hi,

I tried "pip install qutip" -> cannot fetch index base url HTTPS://pypi.python.org/simple

could not find any download etc ...

Stéphane

[jrjoh...@gmail.com]

I'm not sure why pip doesn't find the qutip package (because it is available on pypi: https://pypi.python.org/pypi/qutip/3.1.0), but you get manually install the source release here

http://qutip.org/downloads/3.1.0/qutip-3.1.0.tar.gz

and then run

pip install qutip-3.1.0.tar.gz

from the directory where you saved it.

ps.

When you report a problem, it is useful if you provide the full error message, even if it is be very verbose.

Rob

​

[Stéphane Le Bec]

Sorry,

The full error message is:

"Cannot fetch index base URL https://pypi.python.org/simple/

Could not find any downloads that satisfy the requirement qutip

Cleaning up

No distributions at all found for qutip"

[Stéphane Le Bec]

I retrieve the qutip package https://pypi.python.org/pypi/qutip/3.1.0

put it under Anaconda\pkgs

then run pip install qutip-3.1.0.tar.gz from this directory Anaconda\pkgs

I have this error message

error: Command "gcc -O2 -Wall -Wstrict-prototypes -D__MSVCRT_VERSION__=0x0900 -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\lib\site-packages\numpy\core\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\lib\site-packages\numpy\core\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\lib\site-packages\numpy\core\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\PC" -c qutip\cy\spmatfuncs.c -o build\temp.win32-2.7\Release\qutip\cy\spmatfuncs.o -w -ffast-math -O3 -march=native -mfpmath=sse" failed with exit status 1

Thank you for helping

[Stéphane Le Bec]

specification : I work with a 32 bit-bit version of Anaconda. Is it supported with version qutip-3.1.0 ?

[jrjoh...@gmail.com]

Myself, I have never used the 32 bit version of Anaconda on windows, and I don't know of anyone else who has either, so there might be unresolved issues with this system configuration. Can you run the failing command directly in the command prompt and show the full error message from gcc? I mean, run the following from the qutip source code directory:

gcc -O2 -Wall -Wstrict-prototypes -D__MSVCRT_VERSION__=0x0900 -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\lib\site-packages\numpy\core\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\lib\site-packages\numpy\core\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\lib\site-packages\numpy\core\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\include" -I"C:\Documents and Settings\lecrass\Local Settings\Application Data\Continuum\Anaconda\PC" -c qutip\cy\spmatfuncs.c -o build\temp.win32-2.7\Release\qutip\cy\spmatfuncs.o -w -ffast-math -O3 -march=native -mfpmath=sse

[Stéphane Le Bec]

I did it 

The beginning is missing but I think it is not the most important.

It seems there is a problem with "C:\Documents' is not recognized as an internal or external command" see below.

In fact I made the default installation.

Perhaps I should have try an other folder at the beginning of the installation (I mean directly under C:\)

In fact, I try to change of folder at the beginning of install and create a folder Anaconda but it said that it already exist ...

So I chose the default one under :\Documents and Settings...

I hope that it is clear.

[Stéphane Le Bec]

In fact I try to choose the folder directly under C:\Anaconda at the installation  but It said "the folder already exists".

So I did not pursue and chose the default one.

Hi

I don't understand French, but I am guessing that it might help if you install the python-dev package if you haven't done so already (it should provide the Python.h file):

sudo apt-get install python-dev

​

rob

[Stéphane Le Bec]

Bonsoir Rob,
In fact I installed the package python-all-dev as you recommande.
And then I launched "pip install qutip"
the message "successfully installed qutip" appeared :-)
I have now to review in details documentation.
In fact I am interesting first with statistical programms (use of Monte-Carlo algorithm for example)
But I am sure that QUTIP can offer many utilities studying for example models of particles like bosons or fermions.
In any case thank you very much for the help Rob without forgetting Paul.
Regards,
Stéphane

Rob,

I am trying to install qutip with no success.  I am on a mac and when I use "sudo pip install qutip-3.1.0.tar.gz" it fails because of "Command "//anaconda/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip-q68ljfpe-build/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-uq2f1_hp-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-q68ljfpe-build"

[anubha...@gmail.com]

Hello Robert and Paul,

I have spent a lot of time today just to install qutip. 

1. The recipe that you guys have written on your website, doesn't work. Installing Python(x,y) and following the conditions. 

2. Reading this thread, I tried installing Anaconda, and I am getting the same error that I was getting when I had Python(x,y). 

If you guys can please fix this situation for Windows machines, and have a solid installation guide that works, that would save a lot of time of people. 

This is the error that I got!!
