I tried `polars` via Explorer from Elixir, and it shit the bed in an entirely different way:

``` df = Explorer.DataFrame.from_csv(filename = "my_file.txt", delimiter: "|", infer_schema_length: nil) {:error, {:polars, "Could not parse `OTHER` as dtype Int64 at column 3.\nThe current offset in the file is 4447442 bytes.\n\nConsider specifying the correct dtype, increasing\nthe number of records used to infer the schema,\nrunning the parser with `ignore_parser_errors=true`\nor adding `OTHER` to the `null_values` list."}} ```

Note, I added `infer_schema_length: nil` assuming that the data type discovery via sampling was just less good in `polars`, since this would have it read the whole file before determine types, but it still failed.
