Spyder或者Jupyter中重复运行Tensorflow的代码,会出现变量已经存在的问题。这是因为这些编辑器都会自动保存变量。
具体错误描述:
ValueError: Variable Actor/eval0/l1/kernel already exists, disallowed. Did you mean to set reuse=True or reuse=tf.AUTO_REUSE in VarScope? Originally defined at: File "C:\Users\23820\AppData\Roaming\Python\Python37\site-packages\tensorflow\python\framework\ops.py", line 1990, in __init__ self._traceback = tf_stack.extract_stack() File "C:\Users\23820\AppData\Roaming\Python\Python37\site-packages\tensorflow\python\framework\ops.py", line 3536, in _create_op_internal op_def=op_def) File "C:\Users\23820\AppData\Roaming\Python\Python37\site-packages\tensorflow\python\framework\op_def_library.py", line 750, in _apply_op_helper attrs=attr_protos, op_def=op_def) File "C:\Users\23820\AppData\Roaming\Python\Python37\site-packages\tensorflow\python\ops\gen_state_ops.py", line 1752, in variable_v2 shared_name=shared_name, name=name) File "C:\Users\23820\AppData\Roaming\Python\Python37\site-packages\tensorflow\python\ops\state_ops.py", line 79, in variable_op_v2 shared_name=shared_name)
2.1.直接删除变量,再运行或者重新打开Python的kernel刷新变量。
2.2.在代码中加入tf.reset_default_graph()
来清理tensorflow中的默认图。
