Graph.importGraphDef介绍

[英]Import a serialized representation of a TensorFlow graph.

The serialized representation of the graph, often referred to as a GraphDef, can be generated by #toGraphDef() and equivalents in other language APIs.
[中]导入TensorFlow图的序列化表示形式。
图的序列化表示(通常称为GraphDef)可以由#toGraphDef()和其他语言API中的等价物生成。
