Data preprocessing method and device, computer equipment, storage medium and computer program product

The invention relates to a data preprocessing method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: determining the output length of a preprocessing operator of an attention mechanism; determining the number of threads participating in preprocessing for each traffic participant according to the maximum number of threads which can be supported by the graphics processor and the number of the traffic participants; according to the number of the map points and the number of the threads, determining a map point range which is responsible for processing by each thread on the automatic driving map; for each thread, screening out a target map point of which the correlation with the corresponding traffic participant meets a preset condition from a map point range which is responsible for processing through the current thread, taking a combination formed by each target map point and the corresponding traffic participant as a to-be-processed dat
