Question

当将poisson GLM拟合到数据集时 - 我收到此错误代码（错误：来自localhost / 127.0.0.1的DistributedException：54321：'null'，由java.lang.NegativeArraySizeException引起）并且难以理解为什么会发生这种情况。我在下面发布了一个可重复的示例，其中的玩具数据集与我的数据集和我正在使用的参数大致相似：

df <- data.frame(count = c(512,1025,234,324),gene = c("gene_1","gene_2","gene_1","gene_2"),factor = c(1,2,3,4),factor_2 = c("a","b","c","d"),bound = c("bound","unbound","bound","unbound"))
df <- as.h2o(df)
intx_terms_suppress <- c("factor_2.a","factor_2.b","factor_2.c","factor_2.d","bound.bound","bound.unbound")
constraints <- data.frame(names=intx_terms_suppress, 
                      lower_bounds=0, 
                      upper_bounds=0, 
                      beta_given=0)
y <- 1
train <- c("gene","factor","factor_2","bound")
interactions <- list(c("factor_2", "bound"))
df[,1] <- as.numeric(df[,1])
df[,2:5] <- as.factor(df[,2:5])
fit <- h2o.glm(y = y, x = train, training_frame = df, family = "poisson", standardize = FALSE, interaction_pairs = interactions, beta_constraints = constraints)

我感谢任何人可能提供的任何帮助。谢谢你！

h2o：'null'，由java.lang.NegativeArraySizeException引起
