ValueError: Variable generator/Conv/weights/Adam/ does not exist, or was not created with...

錯誤：

多GPU設置時出現如下錯誤：ValueError: Variable E_conv0/w/Adam/ does not exist, or was not created with tf.get_variable(). Did you mean to set reuse=None in VarScope?

原因：

代碼中有tf.get_variable_scope().reuse_variables()，但卻缺少上下文管理的APItf.varibale_scope().

解決方法：

在設置GPU的位置添加如下命令：with tf.variable_scope(tf.get_variable_scope()) as scope:

with tf.variable_scope(tf.get_variable_scope()) as scope:
    for i in range(args.num_gpus):
        with tf.device('gpu:%d' % i):
            with tf.name_scope("%s_%d" % ('Tower', i)):
            ...
            tf.get_variable_scope().reuse_variables()
