A neural network processing method, comprising the following steps: obtaining a model dataset and model structure parameters of an original network (S); obtaining an operational attribute of each compute node in the original network; operating the original network according to the model dataset and the model structure parameters of the original network and the operational attribute of each compute node, to obtain an instruction corresponding to each compute node in the original network (S); and if the operational attribute of the current compute node is a first operational attribute, storing a network weight and the instruction corresponding to the current compute node into a first non-volatile memory, so as to obtain a first offline model corresponding to the original network (S). Further provided are a computer system and a storage medium. The neural network processing method, the computer system, and the storage medium shorten the time for a processor to operate the same network, and improve the processing speed and efficiency of the processor.
