   @zhreshold Agreed. Seems that OpenCV works will with multithreading but not with multiprocessing. See a few issues on their Github related to this (e.g. https://github.com/opencv/opencv/issues/5150).
   
   Almost certain that @ThomasDelteil's suggestion will work though, it's used by `ImageFolderDataset` for example. It still uses OpenCV but calls it using an internal process.
