Column indices are out of range

[TommyDong1998]

The error "column indices are out of range error" appears when I try
regression.train([[73, 80],[93, 88]],[152,182])

Uncaught RangeError: column indices are out of range

Have you resolved this yet? I'm having the same problem.

I know this very late as a reply to this issue, but I ran into the same issue and believe I have identified the cause.

The bagging/out-of-bag process in examplesBaggingWithReplacement fails non-deterministically (depending on the seed and dataset), with much higher probabilities for small datasets like yours. This makes toy and test examples unstable. It doesn't crash immediately, but it generates empty OOB sets which causes a crash later in the training process.

I'll submit a full bug report.
