nodeRNN input

[shaoxuan92]

Hello, great paper and code provided! Thank you! But I have a question about the the input of nodeRNN(torso for instance). The paper says the nodeRNN(torso) concatenates the nodeFeatures(torso) and outputs of corresponding edgeRNNS(torso_input, torso_arm, torso_leg)[AS SEEN IN FIG.4]. But in the implementation(configuration: srnn), I found that there is no nodeFeatures(torso) sent into the nodeRNN(torso). Is that right? Besides, in the code, does the 'torso_input' mean 'torso_torso temporal edgeRNNs'? Very much looking forward to your reply!
