dreye.datasets.load_flowers#

dreye.datasets.load_flowers(as_wide=False, label_cols='data_id')[source]#

Load a set of flower reflectances as a dataframe.

Parameters:
as_widebool, optional

Whether to return the dataframe as a wide-format dataframe.

label_colsstr or list-like, optional

The column pandas.MultiIndex, if as_wide is True.

Returns:
dfpandas.DataFrame
A long-format pandas.DataFrame with the following columns:

  • country

  • flower_genus

  • human_color

  • is_main_color

  • info_id

  • bee_color

  • part_of_flower

  • data_id

  • flower_species

  • wavelengths

  • reflectance

  • flower_family

The columns attribute is a pandas.MultiIndex in wide-format.
