    Abstract: The present disclosure relates to a data processing method, a device, an electronic device, and a readable storage medium. When the above are adopted, a target neural network is subject to a subnet classification. The target neural network includes at least one subnet. When the method is adopted, at least during the process of compiling and running the subnets, only one input operation and one output operation are required. Whereas when the network layers of the subnet are compiled and run layer by layer, pluralities of input operations and output operations are required. Therefore, the data processing method is more efficient and is capable of improving the operation rate.
