class_blobs is not the same shape as points_mask

[Lyhour-Chhay]

blob_uniques, blob_counts = np.unique(class_blobs * points_mask, return_counts=True) #blob_uniques now only contains labelled points that are inside a predicted blob

in this statement of coding, the class_blobs should has the same shap as point_mask for multiple matrix. However, when I run it, it is error due to different shape. How to solve this problem
