[zhq99]

Hi~
when I debug, there was something wrong. I was wondering if you could kindly help me?

The information is

• Experiment error traceback (use --gdb to debug) -
  experiment.py : 175 : execute : self.main()
  run.py : 199 : main : Experiment().run()
  run.py : 72 : run : env_dtype=str(self.env.action_space.high.dtype))

  ddpg_nets_dm.py : 50 : policy : summary = hist_summaries(h0,h1,h2,h3,action)
  ddpg_nets_dm.py : 8 : hist_summaries : return tf.summary.merge_all([tf.summary.histogram(t.name,t) for t in args])
