[TRAGDOR]

help, it doesnt work for all of them, im assuming "T" comes with tensorflow.
#render_deepdream(T(layer)[:,:,:,139], img0) #og from vid
#render_deepdream(tf.square(T('mixed4c')), img0) #from siraj github
#render_deepdream(T(layer)[:,:,:,139], img0, iter_n=20, step=1.5, octave_n=4)
#render_deepdream(tf.square(T('mixed4c')), img0, iter_n=20, octave_n=10)
#render_deepdream(T(layer)[:,:,:,139], img0, iter_n=20, octave_n=19)
#render_deepdream(T(layer)[:,:,:,65]+T(layer)[:,:,:,139], img0, iter_n=20, octave_n=12)
