郑州酒店网站建设,iis做网站跳转,宁波seo公司推荐,自己做的网站打开太慢当我们加载了一个ONNX之后#xff0c;我们获得的就是一个ModelProto#xff0c;它包含了一些版本信息#xff0c;生产者信息和一个GraphProto。在GraphProto里面又包含了四个repeated数组#xff0c;它们分别是node(NodeProto类型)#xff0c;input(ValueInfoProto类型)我们获得的就是一个ModelProto它包含了一些版本信息生产者信息和一个GraphProto。在GraphProto里面又包含了四个repeated数组它们分别是node(NodeProto类型)input(ValueInfoProto类型)output(ValueInfoProto类型)和initializer(TensorProto类型)其中node中存放了模型中所有的计算节点input存放了模型的输入节点output存放了模型中所有的输出节点initializer存放了模型的所有权重参数。 这里用python将onnx中包含的有用的信息打印出来进行一个直观可视化。
整体流程
解析graph input解析graph output解析graph initializer模型的所有权重参数解析graph node打印op信息输入输出得到整个计算的graph
