Network equipment fault analysis method and device and storage medium

The invention provides a network equipment fault analysis method and device and a storage medium, relates to the technical field of data processing, and is used for determining data features associated with target alarm information so as to accurately position fault causes. The method comprises the steps of obtaining a target classification model obtained through pre-training; the target classification model is used for judging whether the to-be-detected network equipment generates target alarm information or not according to data features corresponding to the operation data of the to-be-detected network equipment; the target classification model is obtained through training based on data features corresponding to operation data of multiple sample network devices and labels of the multiple sample network devices, and the labels comprise generation of target alarm information or no generation of the target alarm information; and determining the importance degree of each data feature in the target classificatio
