Error in if (class(A_norm) != "matrix") { : the condition has length > 1 此外: Warning message: In asMethod(object) : sparse->dense coercion: allocating vector of size 5.9 GiB

When I ran scMetabolism to quantify metabolic activity ，I met some problem：
library(Seurat)
library(scMetabolism)
scRNA <- readRDS('object.RDS')
countexp.scRNA <- sc.metabolism.Seurat(obj = scRNA, method = "AUCell", imputation = T, ncores = 2, metabolism.type = "KEGG")
Your choice is: KEGG
Start imputation...

Is there anyone encounter the same error, and how to solve it? thank you?
