输入数据后，我的程序是cv.glmnet(x,y,family="binomial",type.measure="auc")，运行后，出现警告，too few observations per fold for type.measure.auc in cv.lognet,changed to type.measure=deviance
,alternatively.,use smaller value for nfolds,
我把nfolds的值改为小于10，然后在运行cv.glmnet(x,y,family="binomial",type.measure="auc"，nfolds=8)，运行plot没反应啊，没有图形产生，请大神帮忙看看
