搞了几天终于把这个给搞得差不多了，遇到的错误这里也记录一下：

一、配置【配置什么的300和512其实差不多，这里只举一个例子来分析一下】

　之前的文件修改什么的和300x300的一样：https://www.cnblogs.com/GrPhoenix/p/10018072.html

从自己训练的ssd_300_vgg模型开始训练ssd_512_vgg的模型

      因ssd_300_vgg中没有block12,又因为block7,block8,block9,block10,block11,中的参数张量两个网络模型中不匹配，因此ssd_512_vgg中这几个模块的参数不从ssd_300_vgg模型中继承，因此使用checkpoint_exclude_scopes命令指出。

         因为所有的参数均需要训练，因此不使用命令--trainable_scopes

另外由300转512后还需修改：

1. 首先修改ssd_vgg_512.py的训练类别

2.修改train_ssd_network.py的model_name

   修改为ssd_512_vgg

3. 修改nets/np_methods.py

    修改：将300改为512， 将类别改为自己数据的类别（+背景）

4. 修改preprocessing/ssd_vgg_preprocessing.py

    修改：将300改为512

5. 修改ssd_notbook.ipynb

   a  将文件中数字“300”改为“512”

其他修改可以参考：http://blog.csdn.net/liuyan20062010/article/details/78905517

二、我遇到的错误：

InvalidArgumentError (see above for traceback): Restoring from checkpoint failed. This is most likely due to a mismatch between the current graph and the graph from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint. Original error:

Assign requires shapes of both tensors to match. lhs shape= [84] rhs shape= [8]
	 [[{{node save/Assign_20}} = Assign[T=DT_FLOAT, _class=["loc:@ssd_512_vgg/block12_box/conv_cls/biases"], use_locking=true, validate_shape=true, _device="/job:localhost/replica:0/task:0/device:GPU:0"](ssd_512_vgg/block12_box/conv_cls/biases, save/RestoreV2/_41)]]
	 [[{{node save/RestoreV2/_104}} = _Send[T=DT_FLOAT, client_terminated=false, recv_device="/job:localhost/replica:0/task:0/device:GPU:0", send_device="/job:localhost/replica:0/task:0/device:CPU:0", send_device_incarnation=1, tensor_name="edge_110_save/RestoreV2", _device="/job:localhost/replica:0/task:0/device:CPU:0"](save/RestoreV2:52)]]

　　这类的问题本质上来说还是自己的配置不对，这个问题我查了很久，最后发现实在是太simpleT-T。

　　我的问题的话：在从300转到512的时候忘记改ssd_vgg_512.py的类别导致test的时候文件配置和训练的tensor  shape不匹配TT...
