hi, all, I find when my reading from a big 10x matrix file, it gives me below error: numpy.core._exceptions.MemoryError: Unable to allocate 926. GiB for an array with shape (6794880, 36601) and data type float32

This is not an issue with this tutorial, but rather your environment not having enough RAM for this big dataset.
