I cannot reproduce these errors in 0.3.4 or 0.3.5 using the PyPi files in Python 2.7. I'm not sure what archtester could be doing differently from nosetests or running test_oct2py.py directly. What versions of numpy and scipy are you using?

Is your OS 64 bit? Also, what version of octave do you have?

from oct2py.

Is 32 bit - XP SP3.
I used this octave: octave-3.6.2-vs2010-setup.exe

from oct2py.

How about your setup, @idella?

from oct2py.

I was not able to reproduce the errors on Windows 7, but my OS and my Octave were 64 bit. However, on Linux Mint 14 64 bit, I can reproduce the same errors as @idella. Wow, it took me 4 months to think of 32 vs. 64 bit, sorry @idella. I will get to hacking on a solution.

from oct2py.

@idella, @klonuo, I believe I have addressed all of your concerns. If you do not mind, please install and test the latest source and make sure it passes on your machine. I will push a new version of oct2py this weekend. Thanks again.

from oct2py.

@blink1073, unfortunately I get exact same errors with current git version

I double checked numpy and scipy tests, but they pass fine, just some ufunc warnings and the like

the rest a repeat of the above, sadl, do klonuo

from oct2py.

@idella, @klonuo, can you verify that in the directory found this way:

>>> import oct2py
>>> oct2py.__file__ 

In the file _matwrite.py, there is the line:

        if data.dtype.name in ['float128', 'complex256']:

from oct2py.

Otherwise, you can do the following:
pip install https://github.com/blink1073/oct2py/archive/master.zip

from oct2py.

@idella, @klonuo, can you verify that in the directory found this way: ...

In [9]: import oct2py
   ...: oct2py.__file__
   ...: 
Out[9]: 'C:\\Python27\\lib\\site-packages\\oct2py\\__init__.pyc'

In [11]: !type _matwrite.py | findstr float
        Currently the following types supported: float96, complex192, void
        if data.dtype.name in ['float128', 'complex256']:

from oct2py.

@klonuo, lets figure out which typecode causes the error, can you please make the following patch and give the output?

It's *float64* for g and *complex128* for G

from oct2py.

@klonuo, right, but those two datatypes types fail on some configurations (including mine), so I do not support them.

from oct2py.

@klonuo , what does the following show for you?

import numpy
test = numpy.ones(1)
test = test.astype('g')
print test.dtype.str, test.dtype.name

from oct2py.

those two datatypes types fail on some configurations (including mine)

So, why don't you see the same test errors?

what does the following show for you?

<f8 float64

from oct2py.

@klonuo, on my machine, it is properly typecast as a float128 and an Oct2PyError is raised, as expected. I'm not sure why it is not cast on your machine. Can you try the following patch?
