AttributeError using pyBrain _splitWithPortion - object type changed?

Question

I\'m testing out pybrain following the basic classification tutorial here and a different take on it with some more realistic data here. However I receive this error when applyi

Answer 1

I tried the suggested workaround from Muhammed Miah, but I still was tripped up when running the tutorial at the line:

print( trndata['input'][0], trndata['target'][0], trndata['class'][0])

trndata['class'] was an empty array, so index [0] threw a fault.

I was able to workaround by making my own function ConvertToOneOfMany:

def ConvertToOneOfMany(d,nb_classes,bounds=(0,1)):
  d2 = ClassificationDataSet(d.indim, d.outdim, nb_classes=nb_classes)
  for n in range(d.getLength()):
    d2.addSample( d.getSample(n)[0], d.getSample(n)[1] )
  oldtarg=d.getField('target')
  newtarg=np.zeros([len(d),nb_classes],dtype='Int32')+bounds[0]
  for i in range(len(d)):
    newtarg[i,int(oldtarg[i])]=bounds[1]
  d2.setField('class',oldtarg)
  d2.setField('target',newtarg)
  return(d2)
