I had verified that the repo is the latest version, and other proper installations as well..

I am on Win 10 x64, 8 gigs 4 logical Cores.

The weird part is on removing the xgb, it works absolutely perfect ( I am having xgb at the end of the 2nd level)

[gdragone1]

same problem. Would you fix it?

[gdragone1]

@goldentom42 Sorry to @, I want to know can you fix it. Thank you!

[goldentom42]

I don't think I can really. Are you on win 10 as well ? I usually run things on Ubuntu :(

[gdragone1]

Run on Ubuntu too, but this mistake also happened.

[gdragone1]

Maybe I know the reason. Because I always failed to generate the sparse files, then I delete a part of data from test file, but I forgot to delete the pred_file. That is , I didn't keep data consistent between test and pred file. I will try again.

@gdragone1 Thanks. I'll have trouble reproducing this since my processing power is dedicated to Malware competition ;)
