1. A picture prediction method, applied to an encoder, the method comprising:
determining an initial prediction value of a to-be-predicted colour component of a current block;
determining a sample associated with a reference colour component of the current block;
determining side information of the current block according to the sample associated with the reference colour component;
filtering the initial prediction value by using a preset network model and the side information of the current block, to obtain a target prediction value of the to-be-predicted colour component of the current block; and
encoding the to-be-predicted colour component of the current block according to the target prediction value.
