Crashing python when calling mesolve

[Charles Newton]

Hello all,

Some background:

After much heartache, I was able to successfully install qutip on a Windows computer.

Below are the package versions I am currently using

QuTiP Version:      3.1.0

Numpy Version:      1.8.2

Scipy Version:      0.14.0

Cython Version:     0.21.1

Matplotlib Version: 1.4.2

Fortran mcsolver:   False

scikits.umfpack:    False

Python Version:     2.7.9

Platform Info:      Windows (AMD64)

Installation path:  C:\Python27\lib\site-packages\qutip

I have been able to follow through some of the online tutorial from the qutip site.

The problem I am having occurs when I try to call mesolve.

Calling mesolve does not deliver an error message but instead crashes python.

Specifically, this line of code causes the program to crash: 

result = mesolve(H, psi0, tlist, [], [])

Can anyone offer feedback on a possible solution to this problem?

Thanks,

Additionally, I'll add that the test scripts ran successfully until mesolve was tested, at which point python crashed.

I figured it out somehow.

('QuTiP Version:      ', '3.1.0')

('Numpy Version:      ', '1.8.2')

('Scipy Version:      ', '0.14.0')

('Cython Version:     ', '0.21.1')

('Matplotlib Version: ', '1.4.2')

('Fortran mcsolver:   ', 'False')

('scikits.umfpack:    ', 'False')

('Python Version:     ', '2.7.9')

('Platform Info:      ', 'Windows', '(AMD64)')

Same version of Python (x,y) as before.

I had to download MinGW separately and include it in the PATH

Good luck to anyone trying this on Window because it was rather difficult.
