default_dtypes

default_dtypes(*, device: device | None = None) → DefaultDataTypes

Returns a dictionary containing default data types.

The dictionary must have the following keys:

  • "real floating": default real floating-point data type.

  • "complex floating": default complex floating-point data type.

  • "integral": default integral data type.

  • "indexing": default array index data type.

Dictionary values must be the corresponding data type object.

Parameters:

device (Optional[device]) –

device for which to return default data types. If device is None, the returned data types must be the default data types for the current device; otherwise, the returned data types must be default data types specific to the specified device. Default: None.

Note

Some array libraries have the concept of a device context manager, allowing library consumers to manage the current device context. When device is None, libraries supporting a device context should return the default data types for the current device. For libraries without a context manager or supporting only a single device, those libraries should return the default data types for the default device.

Returns:

out (DefaultDataTypes) – a dictionary containing the default data type for respective data type kinds.
