Segmentation fault with external memory training


#1

I am using external memory training with #dtrain.cache as a suffix for the training data file. I am getting segmentation fault errors.

I saw this https://github.com/dmlc/xgboost/issues/1133 but it seems people got resolved with a fix. Any pointers on how can I avoid segmentation fault with external memory training ?

You would need to provide some more information about what you are trying to do. Could you post your scipt and the output you get if you run the program with valgrind?

Can you open an issue and describe your settings, preferably with a reproducible script and example data? Thanks.
