Hi! I saw in another issue that you explain the funtion 'induce_parent', saying its purpose is to attach imagenet21k and related node to the xml-node. I find this line confusing. Base on your explanation in the aforemetioned issue, I presume that this line should check whether one parent node belongs to xml-node but find it checking imagenet21k-node, and I'm therefore lost. Another thing is that there doesn't seem to be a line attaching the missing node itself to the xml-node. Could you enlighten me about this? - Issue
