Installation issue on windows using octave

[ghost]

Hi,

I am trying to install hctsa using octave engine and anaconda python 2.7 on windows. I have added octave to my path. However, now I get this error message:

(base) C:\Temp\octave-4.0.0\bin>hctsa-cli install --engine octave

Any help would be appreciated.

I've never tested how far you can get using octave to run hctsa. I suspect not too far, although I'd be curious how many algorithms will run properly in octave (rather than Matlab). I can't help with any specific pyopy issues, unfortunately.

Windows and octave is a combination that I never tried. As Ben says, even if you make it work, many hctsa operations will not work.

The error you report is a timeout. Since the last time I tried, octave has changed a lot. Most prominently it now starts on a GUI by default. I suspect we would need to add a "--no-gui" somewhere.

A quick search shows this: blink1073/oct2py#82

So set OCTAVE_EXECUTABLE accordingly to your octave version and we should be good to go (at least for this error).

As I said, these are uncharted territories. Before even playing with pyopy I would first try hctsa directly in octave to check if the operations you need can work.
