Caught and logged exception with randomforest

Thanks for the bug report! Do you have a stack dump?

[mschulkind]

That's it because the random forest implementation swallows it.

The interesting thing is that the forest still appears to work correctly
after that.

I'm pretty sure the log line comes from here:
https://github.com/haifengl/smile/blob/master/Smile/src/smile/regression/RandomForest.java#L335

[haifengl]

Thanks! Can you please change that line to ex.printStackTrace() and run it again?

[haifengl]

Fixed. Can you try version 1.0.2? Thanks! If your machine is multi-core, it should be faster now.

@mschulkind Any updates? Thanks!

Sorry for the delay. I was out of town.

I just updated and I no longer get the exception. Thanks.

Any idea why my example never exits though? It seems like it must be
hanging on a background thread or something. If I simple comment out the
line to create the random forest, it exits cleanly, but with it, it just
hangs, although it does return from the call to new.

Do you mean that everything runs fine and you get all results, but the program doesn't exit? Or the program hangs in the creating the random forest? Thanks!

[mschulkind]

Things run, but the program never exits. It hangs after main() returns.

There is a thread pool, shared by many algorithms. If you are the master branch, you can use

smile.util.MulticoreExecutor.shutdown()

at the end of your program to exit smoothly. Thanks!

Thanks!
