Dear community, I am MS data science student and want to work on spatial transcriptomics spot deconvolution using depp learning. I have difficulties in understanding the data. In fact my question is that if I train the model to predict the proportions of different cell types in spots, I need the proportions (labels) to train model and evaluate its performance, but I do not have them. I have downloaded the visium data (https://www.10xgenomics.com/resources/datasets/adult-mouse-brain-ffpe-1-standard-1-3-0) but could not understand how to extract the labels.

Please help me in this regard
