Dynamic graph execution method and device under artificial intelligence graph framework

The invention provides a dynamic graph execution method and device under an artificial intelligence graph framework, and relates to the field of artificial intelligence, in particular to the field of dynamic graph calculation in a deep learning framework. According to the implementation scheme, an artificial intelligence graph framework is obtained, the artificial intelligence graph framework processes first data and comprises a plurality of sub-graphs, and each sub-graph in the sub-graphs indicates corresponding operation to be executed for a corresponding type of tensor in multiple types of tensors obtained based on the first data; at least one target sub-graph in the multiple sub-graphs is obtained, each target sub-graph in the at least one target sub-graph indicates a corresponding operation to be executed for a tensor of a target type corresponding to related data of the first data in the multiple types of tensors, and the data size of the related data is smaller than the data size of the first data; and
