numpy.setbufsize#

numpy.setbufsize(size)[source]#

Set the size of the buffer used in ufuncs.

Changed in version 2.0: The scope of setting the buffer is tied to the numpy.errstate context. Exiting a with errstate(): will also restore the bufsize.

Parameters:
sizeint

Size of buffer.

Returns:
bufsizeint

Previous size of ufunc buffer in bytes.

Examples

When exiting a numpy.errstate context manager the bufsize is restored:

>>> with np.errstate():
...     np.setbufsize(4096)
...     print(np.getbufsize())
...
8192
4096
>>> np.getbufsize()
8192
