xarray.set_options

class xarray.set_options(**kwargs)[source]

Set options for xarray in a controlled context.

Parameters

  • arithmetic_join ({"inner", "outer", "left", "right", "exact"}, default: "inner") – DataArray/Dataset alignment in binary operations.

  • cmap_divergent (str or matplotlib.colors.Colormap, default: "RdBu_r") – Colormap to use for divergent data plots. If string, must be matplotlib built-in colormap. Can also be a Colormap object (e.g. mpl.cm.magma)

  • cmap_sequential (str or matplotlib.colors.Colormap, default: "viridis") – Colormap to use for nondivergent data plots. If string, must be matplotlib built-in colormap. Can also be a Colormap object (e.g. mpl.cm.magma)

  • display_expand_attrs ({"default", True, False}:) – Whether to expand the attributes section for display of DataArray or Dataset objects. Can be

    • True : to always expand attrs

    • False : to always collapse attrs

    • default : to expand unless over a pre-defined limit

  • display_expand_coords ({"default", True, False}:) – Whether to expand the coordinates section for display of DataArray or Dataset objects. Can be

    • True : to always expand coordinates

    • False : to always collapse coordinates

    • default : to expand unless over a pre-defined limit

  • display_expand_data ({"default", True, False}:) – Whether to expand the data section for display of DataArray objects. Can be

    • True : to always expand data

    • False : to always collapse data

    • default : to expand unless over a pre-defined limit

  • display_expand_data_vars ({"default", True, False}:) – Whether to expand the data variables section for display of Dataset objects. Can be

    • True : to always expand data variables

    • False : to always collapse data variables

    • default : to expand unless over a pre-defined limit

  • display_max_rows (int, default: 12) – Maximum display rows.

  • display_style ({"text", "html"}, default: "html") – Display style to use in jupyter for xarray objects.

  • display_width (int, default: 80) – Maximum display width for repr on xarray objects.

  • file_cache_maxsize (int, default: 128) – Maximum number of open files to hold in xarray’s global least-recently-usage cached. This should be smaller than your system’s per-process file descriptor limit, e.g., ulimit -n on Linux.

  • keep_attrs ({"default", True, False}) – Whether to keep attributes on xarray Datasets/dataarrays after operations. Can be

    • True : to always keep attrs

    • False : to always discard attrs

    • default : to use original logic that attrs should only be kept in unambiguous circumstances

  • use_bottleneck (bool, default: True) – Whether to use bottleneck to accelerate 1D reductions and 1D rolling reduction operations.

  • warn_for_unclosed_files (bool, default: False) – Whether or not to issue a warning when unclosed files are deallocated. This is mostly useful for debugging.

Examples

It is possible to use set_options either as a context manager:

>>> ds = xr.Dataset({"x": np.arange(1000)})
>>> with xr.set_options(display_width=40):
...     print(ds)
...
<xarray.Dataset>
Dimensions:  (x: 1000)
Coordinates:
  * x        (x) int64 0 1 2 ... 998 999
Data variables:
    *empty*

Or to set global options:

>>> xr.set_options(display_width=80)  
<xarray.core.options.set_options object at 0x...>
