Label meaning

[Jingling1]

Dear contributors:

the label of each frame has the indices from 0 to 14, but only the indices of 0, 1, 7, 8, 14 are used
I'm interested in the meaning of label[2:7] and label[9:14]

Thanks for your help!

Your code is like:

for label in labels:
triplet = label[0:1]
if triplet[0] != -1.0:
triplet_label[triplet[0]] += 1
tool = label[1:7]
if tool[0] != -1.0:
tool_label[tool[0]] += 1
verb = label[7:8]
if verb[0] != -1.0:
verb_label[verb[0]] += 1
target = label[8:14]
if target[0] != -1.0:
target_label[target[0]] += 1
phase = label[14:15]
if phase[0] != -1.0:
phase_label[phase[0]] += 1
