mantispy.settings.override

settings.override(*, cache_dir=<no change>, stream_bytes=<no change>)

Provides local override via keyword arguments as a context manager.

Parameters:

cache_dir Path (default: <no change>)

Where mantispy.ds keeps the datasets it downloads.

stream_bytes int (default: <no change>)

How many bytes of a matrix that is not in memory a grouped operation reads at once.

The default is a sixteenth of the machine’s memory, between 256 MB and 4 GB. Groups are packed into reads of about this size, and a group larger than that is read a block of columns at a time, so a smaller value lowers the peak memory and a larger one reads the file in fewer passes. mantispy.io.read() with lazy=True also sizes its chunks so that one per dask worker fits in this many bytes.

Return type:

AbstractContextManager[None]
