I’m testing out opf/experiments/spatial_classification with category_0, except I’m trying to add a second field, similar to the scalar_1 experiment.
So the csv dataset looks like this:
classification,field1,field2 string,string,string ,, 0,0,0 1,1,1 0,0,0 1,1,1 and so on...
But I’m getting the exception: "Invalid file format: different number of fields in the header rows of file …category_0.csv (3, 0, 3) from nupic/data/file_record_stream.py:
This makes sense as they’re not all the same length, the specials header is empty, but I can’t figure out why I’m getting this error when the original file looks like this:
classification,field1 string,string , 0,0 1,1 0,0 1,1 ...
Does this mean a special value must be defined when adding a second field?
