obscure error with high shrinkage and gbm.perf(OOB,...) #28

Closed az0 closed 9 years ago

az0 commented 10 years ago

When building a gbm with high shrinkage, gbm.perf fails with an obscure error. Could the error be more clear? In the example below the shrinkage is ridiculously high, but it happens on my real data with shrinkage=0.1
