Bad @ATTRIBUTE type at line 993 about liac-arff HOT 10 CLOSED

Is this a duplicate of #59?

I got similar errors when making this library load arff files generated by openSMILE, and I think attributes definitions of arff files like the following make trouble:

@attribute emotion 0,1,2,3

from liac-arff.

@tats-u could you please provide a full file generated by openSMILE which triggers this behaviour?

Here you are: sample_arff.arff.txt

This causes the following error when you try to load it by arff.load:

  File "/home/tatsu16/anaconda3/envs/residue/lib/python3.6/site-packages/arff.py", line 896, in load

I just skimmed the arff guide and cannot find a description of the attribute type in question. Should this be a nominal attribute with the values, 1, 2, 3 and 4? If yes, the correct syntax would be {1, 2, 3, 4}.

I think so. OpenSMILE violates the specification of the ARFF format. Would you like me to open an issue at https://github.com/naxingyu/opensmile/issues?

from liac-arff.

Yes, that would be great.

I will do later, though developers of it seem to show a lackadaisical attitude because all opened issues are left unsolved.

Closing this as OpenSMILE does not produce valid arff. Please add the curly braces manually as a workaround.
