src/Internal/Sparse.hs:125:24: error:
    • Couldn't match expected type ‘Int’ with actual type ‘CSR -> Int’
    • Probable cause: ‘nRows’ is applied to too few arguments
      In the ‘nRows’ field of a record
      In the expression: SparseR {..}
      In an equation for ‘fromCSR’:
          fromCSR csr
            = SparseR {..}
            where
                gmCSR @ CSR {..} = csr
                nRows = csrNRows
                nCols = csrNCols
    |
125 | fromCSR csr = SparseR {..}
