The invention discloses a neural network distributed training method for dynamically adjusting Batch-size, which relates to the technical field of computer neural network distributed training. The method starts from the perspective of processing training data sets, for each computing node in a distributed cluster , which dynamically adjusts the Batch‑size and the division of subdatasets according to its computational power. In this way, the load balancing processing of the distributed training cluster is realized. The distributed neural network training method of dynamically adjusting Batch-size can not only make full use of the computing power of each computing node, but also ensure that each computing node takes approximately the same time to complete the training of the local dataset, thereby reducing the synchronization overhead of the cluster and improving the distribution of the neural network. It can improve the training efficiency and reduce the training time of neural network.
