Oct2py hangs in Windows about oct2py HOT 22 CLOSED

Hi @spinningplates, thanks for the report. Can you open up a "cmd" Window and just type "octave" and let me know if Octave starts?

from oct2py.

Actually, also paste the Octave start prompt if you don't mind.

from oct2py.

Octave is able to start and I have successfully run programs using Octave.

This is copy-pasted after initializing Octave:

@blink1073 I've noticed that anaconda does not work inside a MinGW or Cygwin shell. The Octave binaries for Windows are built with wither MinGW or Cygwin, so maybe there is an incompatibility. How do you install Octave on windows and do you use it with Anaconda on Windows?

I use Git Bash. I also tested with a clean install of oct2py 2.4.0. I'll try upgrading Octave to the latest and see if that makes a difference...

from oct2py.

@spinningplates, I see that 3.8 is an unofficial build for Windows. http://wiki.octave.org/Octave_for_Windows#Octave_3.8_MXE_Builds. I do not want to get into the business of supporting unofficial builds. Its hard enough keeping up with all the environments as is...

from oct2py.

I think we were using 3.8 because of some other issues. How do you find official builds for octave?

from oct2py.

I'll make the docs clearer in that I only support the official builds on Windows and do not support Cygwin. http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/. There's a link to the .NET builds on the installation page.

from oct2py.

@spinningplates Can you try Octave 3.6.4 from the download @blink1073 just shared?

from oct2py.

I think this is why I was using 3.8+ on Ubuntu: #35

BTW, 3.8.1 is the default on 14.04 LTS: http://packages.ubuntu.com/trusty/math/octave

from oct2py.

@moorepants @blink1073 Confirmed that oct2py works in Octave 3.6.4.

from oct2py.

Great. So that's the deal. oct2py likely doesn't work on Windows with anything > 3.6.4.

See if our software works. We may need to modify the matlab code to run with 3.6.4.

from oct2py.

I did have to make some changes to accommodate 3.8 on Linux, but its been working for a couple versions now. It sounds like the pipe behavior may have changed between 3.6 and 3.8 (which led me to go back to pty on Linux). I fear oct2py may never work on Windows with Octave 3.8+. How did you install 3.8 on Windows? I can take a look when I get a spare moment.

from oct2py.

I just downloaded 3.8.2 from here: http://mxeoctave.osuv.de/ and installed as I did the other versions of Octave (in an Octave folder on the C drive). I also manually added the Octave/bin folder to the path to get it to work in Windows command line.

from oct2py.

Fixed! I'll make sure it works still on Linux, and fire off a bug fix release.

from oct2py.

Should be good in v2.4.2, pip install -U oct2py

from oct2py.

Awesome, thanks! I'll pin our software to this version as the dependency (at least for Windows).

from oct2py.

@spinningplates Can you confirm that the 2.4.2 release works?

pip install --upgrade oct2py

will install the new version.

from oct2py.

I've just confirmed that the 2.4.2 release works. Thanks!

from oct2py.

Great! You're very welcome!

from oct2py.

Dear Blink1075
Which version of oct2py does work with Octave 4.0.0 on Windows ?
Thanks in advance
