How can I convert the pb model to caffe? Any suggests? I will appreciate it .

@merria28 , thank you very much for the feedback. MMdnn does not support the TensorFlow "Less" operator currently. It seems that Caffe does not support any control-flow operators like "Less", so I guess that you may not convert the model to Caffe.
