Tricks for Oct2Py on Travis about oct2py HOT 13 CLOSED

It looks like your problem is the fact that Travis runs on Ubuntu 12.04, which has older versions of numpy, scipy, and Octave. You could try using Miniconda in your Travis script to ensure an updated environment.

from oct2py.

Of course, you're still stick with an older Octave, but based on your errors it looks like Scipy specifically is the problem.

from oct2py.

There are two separate errors there. Scipy is not the issue. The code passes fine on this build:

https://travis-ci.org/csu-hmc/Gait-Analysis-Toolkit/builds/17098015

Except for oct2py. The tests run fine on my local machine running Ubuntu 13.10. I could install octave from a ppa for a later version. Do you think that the version of octave in 12.04 doesn't work with oct2py?

from oct2py.

This is an issue with old versions of Octave. Using the latest version everything passes:

https://travis-ci.org/csu-hmc/Gait-Analysis-Toolkit/builds/17109509

What's the oldest version that oct2py supports?

from oct2py.

Well, my goal is to target whichever version of Octave is available on the
LTS version of Ubuntu, which Travis conveniently uses. My test suite runs
fine, but looking at your code it looks like your call to octave.addpath
in motek.py on line #886 is not working, since Octave cannot find the
script. I'll have to try running your code on Ubuntu 12.04 and see what I
can drum up.

Ok, let me know if you need some help debugging it.

from oct2py.

Okay, under Octave v3.2.4, the file inertial_compensation.m kicks the following syntax error:

octave:1> type inertial_compensation
parse error near line 46 of file /home/localadmin/inertial_compensation.m

  syntax error

>>> [directory_of_this_file, ~, ~] = fileparts(path_to_this_file);
                               ^

parse error near line 46 of file /home/localadmin/inertial_compensation.m

  syntax error

>>> [directory_of_this_file, ~, ~] = fileparts(path_to_this_file);
                               ^

error: called from:
error:   /usr/share/octave/3.2.4/m/help/type.m at line 56, column 7

So, the first problem is that your code does not run on the older version of Octave. The second problem is that my error message is not helpful. I will fix the latter.

from oct2py.

Fixed. In the next release the traceback would look like so:

>>> octave.inertial_compensation
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/localadmin/oct2py/oct2py/session.py", line 476, in __getattr__
    doc = self._get_doc(name)
  File "/home/localadmin/oct2py/oct2py/session.py", line 442, in _get_doc
    exist = self._eval('exist {0}'.format(name), log=False, verbose=False)
  File "/home/localadmin/oct2py/oct2py/session.py", line 395, in _eval
    timeout=timeout)
  File "/home/localadmin/oct2py/oct2py/session.py", line 660, in evaluate
    self.handle_syntax_error(''.join(resp), main_line)
  File "/home/localadmin/oct2py/oct2py/session.py", line 682, in handle_syntax_error
    raise Oct2PyError(msg)
oct2py.utils.Oct2PyError: Oct2Py tried to run:

If using an m-file script, make sure it runs in Octave

Awesome, didn't mean for you to have to debug my code. Thanks though, and the improvement on error propagation will be very helpful. I'll use my vagrant box for Ubuntu 12.04 for future testing so I don't plague you with my errors.

Glad to help. I just released 1.3.0, so I'm calling this fixed. Cheers.

from oct2py.

I'm not sure what is going on here yet but my code now seems to hang on Travis with the latest version of Oct2py (1.3.0).

Build using Oct2py 1.3.0 times out everytime when running the test that uses a oct2py function:

https://travis-ci.org/csu-hmc/Gait-Analysis-Toolkit/builds/17291466

But runs fine using 1.2.0:

https://travis-ci.org/csu-hmc/Gait-Analysis-Toolkit/builds/17293387

This also hangs on my local machine (Ubuntu 13.10).

It looks like all my changes to allow for keyboard and pexpect resulted in the call to leg2d.m not terminating properly. I'll have to do some more digging...

from oct2py.

Okay, test_gait.py runs fine against the latest master branch on my machine. Can you please verify before I release 1.3.1?
