Implementations of the present specification provide a method for training a relationship recognition model and a method and an apparatus for analyzing an image by using the model. The training method includes: dividing a total relationship class set into K groups, and correspondingly setting K classifiers, where the kth classification space corresponding to any kth classifier includes classification space corresponding to a previous classifier and relationship classes in a kth group; sampling a full set of image samples for the K classifiers to obtain K sample subsets respectively, and inputting the K sample subsets to corresponding classifiers to obtain relationship class prediction results between objects in images; and determining a first loss based on classification losses of the K classifiers, and determining a second loss based on a similarity between relationship class prediction results of different classifiers in the K classifiers for a same pair of objects, so that a relationship recognition model is updated based on the first loss and the second loss.
