Can saved binary file be used if max_bin changes?

[cyfdecyf]

I'm modifying the source code to add a new task "save_binary" to prepare data before running parameter tuning. The python package's Dataset.save_binary uses too much memory, thus I'd rather do it using cli version with two_round=true and force_col_wise=true.

I see max_bin and BinMapper are saved in binary file. So I'm wondering whether binary file can be reused if I change the max_bin parameter to a different value than when save the file?

The max_bin will be fixed after save_binary, and you cannot update it.

@guolinke Thanks for your reply.

I opened a pull request #3592 to prevent binary file with non-matching parameters from being used.

Fixed via #3592.
