CsvLoader

loader.tabular.CsvLoader(unit=None, number_type=None, **kwargs)

Loader for CSV (comma-separated values) files.

CsvLoader provides a general-purpose CSV loader with sensible defaults. Customize by subclassing or by passing configuration to init.

Default Configuration

• Delimiter: comma (,)
• Start column: “start”
• End column: “end” (if present)
• ID column: “id” (if present, else auto-generated)
• Coordinate unit: seconds
• Coordinate type: float

Examples

>>> loader = CsvLoader()
>>> loader.load("events.csv")
>>> print(loader.events.count)

>>> # Custom configuration via subclass
>>> class MyLoader(CsvLoader):
...     start_column = "onset_time"
...     end_column = "offset_time"
...     column_specs = {"pitch": int, "velocity": int}
