Variable Generator/dense/kernel already exists, disallowed.

Jupyter notebook运行下面程序:https://github.com/MorvanZhou/Tensorflow-Tutorial/blob/master/tutorial-contents/406_GAN.py
上面程序是关于GAN的!
出现下面问题:

ValueError: Variable Generator/dense/kernel already exists, disallowed. Did you mean to set reuse=True or reuse=tf.AUTO_REUSE in VarScope? Originally defined at:

  File "<ipython-input-15-11d84ae913e7>", line 34, in <module>
    G_l1 = tf.layers.dense(G_in, 128, tf.nn.relu)
  File "/home/zhumeiqiang/anaconda3/lib/python3.6/site-packages/IPython/core/interactiveshell.py", line 2910, in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)
  File "/home/zhumeiqiang/anaconda3/lib/python3.6/site-packages/IPython/core/interactiveshell.py", line 2850, in run_ast_nodes
    if self.run_code(code, result): 

解决方案:

　　jupyter中有kernel选项，点击选择 “ Restart & RunAll ”，即可解决问题。
