Я получаю ошибку «object» requireNamespaceQuietStop «not found» при запуске моделей через каретку с использованием Rmpi. Я могу запускать модели без Rmpi.
Вот минимальный пример:
> library(mlbench)
> library(doMPI)
> library(caret)
> set.seed(998)
> cl <- startMPIcluster(count=8)
8 slaves are spawned successfully. 0 failed.
> registerDoMPI(cl)
> data(Sonar)
> inTraining <- createDataPartition(Sonar$Class, p = .75, list = FALSE)
> training <- Sonar[ inTraining,]
> testing <- Sonar[-inTraining,]
> fitControl <- trainControl(
method = "repeatedcv",
number = 10,
repeats = 10)
> gbmFit1 <- train(Class ~ ., data = training,
method = "gbm",
trControl = fitControl,
verbose = FALSE)
Error in { :
task 2 failed - "object 'requireNamespaceQuietStop' not found"

Также, вот моя информация о сеансе:
