Depending on the amount of data to process, file generation may take longer.

If it takes too long to generate, you can limit the data by, for example, reducing the range of years.

EN Online stores and auctions are commonly used nowadays. It means that we buy much more on the Internet than in traditional stores. It leads to the case that during looking for the products we need to have precise categories assigned to each of them (to find only records that can be of interest for a consumer). Sometimes it is hard, users make simple mistakes by assigning wrong categories to the product they sell. In this paper, we propose an approach to the analysis of product images and their real categories assignment. The proposed algorithm is based on Convolutional Neural Networks (CNNs). Vision Transformers were also tested and compared with CNNs. Products categories were represented by GS1 GPC brick codes. The maximum accuracy reached around 80%. Based on the discussions with e-commerce experts, it was claimed that such precision is acceptable, as the differences between real and assigned categories were effectively small (change in the class does not segment or family).
