Sparse matrices can also be stored as CSR sparse matrices. I don't have a reprex, if needed i can generate one:
adata <- read_h5ad("adata.h5ad", backed = "r")
x<- fetch_data(adata, "MSI2")
Error in py_call_impl(callable, call_args$unnamed, call_args$named) :
NotImplementedError: The SCUBA Python function fetch_anndata does not know how to handle a matrix of class <class 'anndata._core.sparse_dataset._CSRDataset'>. This ocurred with the matrix at key 'X'.
Run `reticulate::py_last_error()` for details.
