tensorflow 合并模型

Deep-Learning Tensorflow
在这里存个备份，还有些问题没有解决。 raise ValueError(“GraphDef cannot be larger than 2GB.”) 记录一些思路好了。现在是没有生成.meta文件，爆掉应该是因为所有的变量都加载到了默认图里。

tensorflow checkpoint 学习笔记

Deep-Learning Tensorflow
参考资料： What is the TensorFlow checkpoint meta file? TensorFlow: Restoring variables from from multiple checkpoints 合并模型的时候发现.meta一直在累加，而其他数据文件没有改变。因此来探究一下checkpoint的几个文件的含义。

tensorflow variable 学习笔记

Deep-Learning Checkpoint Tensorflow
参考资料： programmers_guide/variables tf/Variable 之前感觉对tensorflow 的variable的理解不是很深刻…跑个模型啥的倒不会有什么问题，但是涉及分布式，模型并行之类的，感觉有些地方还是要理解得仔细一点比较好。

Distributed Tensorflow : Cannot assign a device for operation save

Deep-Learning Tensorflow
是在使用分布式tensorflow遇到的一个错误 报错如下： InvalidArgumentError (see above for traceback): Cannot assign a device for operation ‘save/Rest│| 2 GeForce GTX 1080 On | 0000:08:00.0 Off | N/A | oreV2_888’: Operation was explicitly assigned to /job:worker/task:0/device:CPU:0 but available │| 24% 39C P8 12W / 180W | 0MiB / 8114MiB | 0% Default | devices are [ /job:localhost/replica:0/task:0/cpu:0, /job:localhost/replica:0/task:0/gpu:0 ].

Deep-Learning Tensorflow
感觉资料不是很多，先收集资料好了。 tf-distributed官网文档 SO-between-graph和in-graph的区别 inception.README.md SyncReplicasOptimizer SO_How does ps work in distribute Tensorflow? update:在多个nodes（机）上跑。。。tf默认是异步更新的。。。同步的话。。大概需要syncreplicasoptimizer?
