问逻辑回归法rank基因的时候报错，后面标记基因的表以及所属的细胞是怎么的出来的？

老师您好，

我跑到sc.tl.rank_genes_groups(adata, 'leiden', method='logreg')这句的时候总是出错，错误提示：

ranking genes

C:\Users\81085\PycharmProjects\Brean_Sparta_scRNA_sequencing\venv\lib\site-packages\sklearn\linear_model\_logistic.py:818: ConvergenceWarning: lbfgs failed to converge (status=1):

STOP: TOTAL NO. of ITERATIONS REACHED LIMIT.

Increase the number of iterations (max_iter) or scale the data as shown in:

Please also refer to the documentation for alternative solver options:

不知道怎么解决。

另外，不知道后面那个标记基因的表是怎么得来的，用什么代码吗？还有后面的所属细胞是在哪里找到？

期待回复，感谢！
