Demo not working in Octave #4

Closed imyousuf closed 8 years ago

imyousuf commented 8 years ago

I am interested to do some personal work in Image processing and for this I need Image feature extraction. So this project interests me as a starting point. I am new to Octave, but I have used MatLab in past. I am trying to get the demo to work, for this I did the following (version details are also provided):

$ git clone git@github.com:adikhosla/feature-extraction.git
$ cd feature-extraction/
$ octave

Please help me to get it to work in Octave. Thank you.

@samos123 Can you please see if you faced something similar?

adikhosla commented 8 years ago

Hi Imran,

I've never used Octave before so might not be able to help in depth, but I notice that you did not compile the mex files after downloading. Maybe that could be the issue? Just try running 'compile' in Octave.

imyousuf commented 8 years ago

Thank you Aditya for reaching out and helping me. Here is what happens when I try to compile -

octave:1> compile
mkoctfile: unrecognized argument -outdirwarning: mkoctfile exited with failure status
mkoctfile: unrecognized argument -outdirwarning: mkoctfile exited with failure status
mkoctfile: unrecognized argument -outdirwarning: mkoctfile exited with failure status
mkoctfile: unrecognized argument -outdirwarning: mkoctfile exited with failure status
octave:1> demo

^CDataset: demo
Dictionary building in progress on imran-latitude-e6440..

Basically the compiles work despite some failures but now when I run demo it seems to be waiting for 30+mins, then when I CTRL+C it it says Dictionary building in progress, am I missing anything?

adikhosla commented 8 years ago

Could you try removing the '-outdir ...' flags from compile and copy the files to their appropriate directories, once compiled?

Thanks!

imyousuf commented 8 years ago

Proceeded a little more -

octave:3> demo
warning: load: file found in load path

Its been there for approximately 5mins and I am waiting. Any clue?

adikhosla commented 8 years ago

You should kill the process and re-run it after deleting the 'cache' folder.

imyousuf commented 8 years ago

Something seems to have progressed after deleting the cache dir -

This seems to be a known bug of Octave in Ubuntu 15.04. I am closing this issue for now, if I run into issues after Ubuntu fixes their problem I will reopen it. https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1372202

@adikhosla You are awesome! Thank you for all the help!!

adikhosla commented 8 years ago

Sure, happy to help! Sorry this issue couldn't get resolved! Thank you for trying out the toolbox.

imyousuf commented 8 years ago

I managed to recompile the Debian octave package as mentioned in the bug report above and got the demo to work in Octave. Thank you @adikhosla for your patience.
