在下面的尝试2中，我尝试并行训练两个模型，但我得到了如下所示的错误。我不清楚为什么结果应该与我在Attempt1中获得的结果有任何不同，即testArrivalCast应该与TaylorFcast＆lt; - forecast（Taylor2，h = 80）相同。
Code:
##Attempt 1
Taylor2 <- tbats(tsdat1);
TaylorFcast <- forecast(Taylor2, h=80);
Taylor3 <- tbats(tsdat2);
Taylor3Fcast <- forecast(Taylor3, h=80);
##Attempt 2
library(parallel)
library(forecast)
# Calculate the number of cores
no_cores <- 2
# Initiate cluster
cl <- makeCluster(no_cores)
tbatsList<-list(tsdat1,tsdat2)
tbatsModels<-parLapply(cl, tbatsList,
tbats)
stopCluster(cl)
testArrivalCast<-forecast(tbatsModels[1],h=80)
Error in x - fits : non-numeric argument to binary operator
In addition: Warning message:
