Problems solved by technology

[0004] However, in the existing distributed training methods, the communication calculation ratio of each computing node (the time for the computing node to communicate with other computing nodes and the time for the computing node to perform gradient calculation, the ratio of the two) is relatively high, so that the computing node The utilization rate of hardware resources is not high, which makes the training efficiency of distributed training low

Abstract

The invention discloses a distributed training method and device for a deep learning model and computing equipment. The method comprises the following steps: in each training step, acquiring a predetermined number of training data from a training data set as batch training data; calculating a gradient of a model parameter of the deep learning model on the batch training data, and taking the gradient as a local gradient; calculating an accumulated value of the local gradients of the preset number of training steps as an accumulated gradient; communicating with other computing nodes, and exchanging accumulated gradients of each other; and calculating a gradient average value of the accumulated gradients of all the computing nodes, and updating the model parameters based on the gradient average value.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a distributed training method, device and computing equipment of a deep learning model. Background technique [0002] Deep learning is an increasingly popular computing and machine learning implementation method in the industry, which can be used in various scenarios such as images, voice, video, and machine translation. Taking machine translation as an example, the effect of machine translation based on neural networks has been significantly improved, and it has been continuously developed in recent years. At present, in some languages ​​and scenarios, the translation quality can even reach the level of human translation. [0003] Data Parallel (Data Parallel) is a form of distributed training for deep learning models, which divides the training data into multiple parts and trains on different computing nodes. If the computing nodes do not have shared public me...
