There was a problem hiding this comment.
There's some unclear behaviour for the ignore_column parameter. According to the docs it can be specified for the text files just like the header (which works) and the other params in this test: https://lightgbm.readthedocs.io/en/v3.3.5/Parameters.html#ignore_column. Despite mentioning "text files", only CSV, TSV, and LibSVM (zero-based) are supported (https://github.com/microsoft/LightGBM/blob/master/src/io/parser.cpp#L264-L266) and the sample_data seems to be a valid example and other params do work with it.
