Feb 11, 2019 · Pandas series is a One-dimensional ndarray with axis labels. The labels need not be unique but must be a hashable type. The object supports both integer- and label-based indexing and provides a host of methods for performing operations involving the index. Pandas Series.ravel () function returns the flattened underlying data as an ndarray.
11.09.2017 · The numpy.ravel () functions returns contiguous flattened array (1D array with all the input-array elements and with the same type as it). A copy is made only if needed. Syntax : numpy.ravel (array, order = 'C')
26.02.2020 · The ravel () function is used to create a contiguous flattened array. A 1-D array, containing the elements of the input, is returned. A copy is made only if needed. As of NumPy 1.10, the returned array will have the same type as the input array. (for example, a masked array will be returned for a masked array input)
The instance method ravel () returns the flattened underlying data for a panads Series object. This method is often useful when sending data to interfaces where a pandas Series is not accepted, but a numpy ndarray is accepted. Example: # Example Python program that retrieves the underlying ndarray import pandas as pds

16.02.2018 · Please change the shape of y to (n_samples, ), for example using ravel(). y = column_or_1d(y, warn=True) So I use target_newrdn = target_newrdn.ravel() to modify my target variable but it gave me this: AttributeError: 'DataFrame' object has no attribute 'ravel' I am wondering what the problem was and how can I fix? Can anyone help, please? My code:
pandas.unique(values) Let’s see an example. Since unique() function takes values, you need to get the value of a column using df[columns_list].values.ravel(). # Using pandas.unique() to unique values in multiple columns df2 = pd.unique(df[['Courses', 'Fee']].values.ravel()) print ...
