Issue when model trainOcc in parallel

[woodysung]

Hello,

When running the trainOcc in parallel, the follow error was prompted. But this error was not prompted when not using parallel mode. Attached a reproducible R code for your reference. Thank!

In nominalTrainWorkflow(x = x, y = y, wts = weights, info = trainInfo, : There were missing values in resampled performance measures.**

library(oneClass) library(tidyverse)

register no of CPU cores used

doParallel:::registerDoParallel(7)

get the banana dataset

library(imbalance) data(banana) input_data <- banana

this is the default setting of trControl in trainOcc

cntrl <- trainControl(method = "cv", number = 5, summaryFunction = puSummary, #! classProbs = TRUE, #! savePredictions = TRUE, #! returnResamp = "all", #! allowParallel = TRUE)

tocc <- trainOcc(x=input_data [, -3], y=input_data [, 3], trControl=cntrl, method = "ocsvm") Setting direction: controls > cases Warning messages: 1: In .positiveLabel(y) : Positive label not given explicitly.

puF was used to select the optimal model using the largest value. The final values used for the model were sigma = 0.001 and nu = 0.01.

Hi! I have the exact same error. Did you manage a way around this or are you simply not running the model in parallel?
