load and saving .qu file between Mac and Windows

[Mikkel Heuck]

Hi

I am running a simulation on a Mac: 

QuTiP Version:      3.1.0

Numpy Version:      1.6.2

Scipy Version:      0.11.0

Cython Version:     0.22

Matplotlib Version: 1.1.1

Fortran mcsolver:   True

scikits.umfpack:    False

Python Version:     2.7.5

Platform Info:      Darwin (x86_64)

Installation path:  /Library/Python/2.7/site-packages/qutip

and generating a .qu file with qutip.qsave("filename"). When I try to open the file on my windows machine: 

QuTiP Version:      3.1.0

Numpy Version:      1.9.1

Scipy Version:      0.15.1

Cython Version:     0.21.2

Matplotlib Version: 1.4.2

Fortran mcsolver:   False

scikits.umfpack:    False

Python Version:     3.4.2

Platform Info:      Windows (AMD64)

Installation path:  C:\Python34\lib\site-packages\qutip

I get the following error: 

  File "<ipython-input-11-f9d390548180>", line 1, in <module>

    qload("runNo0_0_states")

  File "C:\Python34\lib\site-packages\qutip\fileio.py", line 280, in qload

    out = pickle.load(fileObject)  # return the object from the file

UnicodeDecodeError: 'ascii' codec can't decode byte 0xbe in position 0: ordinal not in range(128)

I am able to open it on the Mac machine. I attach the file here. I thought it was a version mismatch issue, so I updated my windows machine to qutip 3.1.0. Can it be related to python version mismatch? I can open normal pickle generated files across the two machines...

Thanks,

mikkel

This looks to be an issue with how the strings for the name of the .qu file are handled.  They should always be unicode (utf-8).  I will add a fix for this.

This is fixed in Pull #323.
