Add property columns and index to dask.SparseFrame and increase version to 0.8.0
…ly method for various data types
…ules downgrade to 0.19 until dask releases patch
Hotfix/add signature
Added fillna method
This is useful mainly to avoid dask processes sharing really big arrays in case the categories get really big

was broken if loc returned a single location or integers were used as indexers
if multiindex is contained it is restored when loading. This requires saving of metadata. In case metadata is not available because the file was saved with a previous version the index class is inferred by the array values.
* Fix empty attribute of sparsity.SparseFrame __init__ method did not initialize empty attribute correctly leading to errors when using the dask datastructure. This commit fixes this and adds corresponding tests. * Adjust _is_empty method. if data.nnz == 0 doesn't mean the array is empty it could be an array of purely zeros. replaced this check with a check for zero dimension which clearly indicates an empty frame.
* Possibility to one-hot encode multiple columns. `one_hot_encode` signature significantly changed! * Bump version to 0.12.0 * Fix docstring. * Small refactoring. * Added backward compatibility. * Small bugfix. * Changed interfaces to be (ugly but) consistent with previous version, so that backward compatibility is cleaner. * Use warnings module not to depend on drtools. * Adding prefixes to one-hot-encoded column names. When one-hot-encoding columns that contain same categories, resulting columns must have different names. This feature automatically adds original column name to resulting column name. (See docstrings.)
* Use versioneer to create version strings
Drop single or multiple columns
* Add support to save npz files on s3 * fix ci * fix ci * fix to_npz * Add mock_s3_fs docstring
