ValueError：变量vgg_16/conv1/conv1_1 /权重已存在，不允许

Question

尝试使用现有权重时，我收到了这种错误消息。

ValueError: Variable vgg_16/conv1/conv1_1/weights already exists, disallowed. Did you mean to set reuse=True in VarScope? Originally defined at: 

    File "/usr/local/lib/python2.7/site-packages/tensorflow/contrib/framework/python/ops/variables.py", line 217, in variable 
    use_resource=use_resource) 
    File "/usr/local/lib/python2.7/site-packages/tensorflow/contrib/framework/python/ops/arg_scope.py", line 181, in func_with_args 
    return func(*args, **current_args) 
    File "/usr/local/lib/python2.7/site-packages/tensorflow/contrib/framework/python/ops/variables.py", line 262, in model_variable 
    use_resource=use_resource)

请指点。谢谢。

您不能创建两个具有相同名称的Tensorflow变量。如果您不再需要任何旧变量，则可以使用tf.reset_default_graph()来重置图形。否则，你需要定义示波器：https://www.tensorflow.org/programmers_guide/variable_scope
