ValueError: too many values to unpack

[nag92]

When running python src/unperturbed_perturbed_comparison.py The terminal just sits there and I have to kill it. When I do I get the following error.

Traceback (most recent call last): File "src/unperturbed_perturbed_comparison.py", line 43, in <module> unperturbed_gait_data_1 = load_data('First Normal Walking', paths, tmp) File "/home/nathaniel/perturbed-data-paper/src/utils.py", line 116, in load_data gait_data.inverse_dynamics_2d(*args) File "/home/nathaniel/anaconda2/envs/gait/lib/python2.7/site-packages/gaitanalysis/gait.py", line 213, in inverse_dynamics_2d octave.addpath(m_file_directory) File "/home/nathaniel/anaconda2/envs/gait/lib/python2.7/site-packages/oct2py/core.py", line 539, in __getattr__ doc = self._get_doc(name) File "/home/nathaniel/anaconda2/envs/gait/lib/python2.7/site-packages/oct2py/core.py", line 508, in _get_doc verbose=False, return_both=True) ValueError: too many values to unpack

I recommend using the exact software versions specified in the README. We have not maintained this software since publishing this paper, so any new software you use may have different results. Please list the versions of all the dependencies you are using.

I remade the conda workspace with the following depenance I am on a 16.04 machine.

I also know get an error ImportError: libgfortran.so.1: cannot open shared object file: No such file or directory

[moorepants]

Here is a note about the error: https://github.com/ContinuumIO/anaconda-issues/issues/445

[nag92]

I solved that error but I am still getting ValueError: too many values to unpack error

[moorepants]

Instead of listing every single package you have installed in conda, it would be helpful if you listed only the packages that are listed in the README.

[nag92]

I think that is has to do with Oct2py. That seems to be what is throwing the error

numpy 1.9.1, oct2py 2.4.2, pandas 0.15.1, pytables 3.1.1, python 2.7.13, pyyaml 3.11, scipy 0.14.0 , seaborn 0.5.0, libgfortran 1.0, dynamicisttoolkit 0.3.5, gaitanalysistoolkit 0.1.2, matplotlib 1.4.2, pygments 2.0.1

[nag92]

It was a problem with Octave, I was using 4.x, I uninstalled it and installed 3.8.2 and it work.

[moorepants]

Good, glad you found the error. I think that GaitAnalysisToolkit needs to be updated to work with current dependency versions.

[moorepants]

FYI, GaitAnalysisToolKit has been updated to work with recent dependency versions.
