Exception: Invalid range given to ner_training_instance.overlaps_any_entity(). It overlaps an entity given to a previous call to add_entity().

sample=[]
for i in range(0,len(with_annot_list)):
samp=ner_training_instance(tok[i])
sample.append(samp)

for i in range(0,len(tok)):
sample[i].add_entity(xrange(first[i],second[i]),"Clause")

Where tok is list of lokenized strings and first is the list of integers and second also.
