It is also good, but this record is not a normal numpy array. For instance, type(record[0]) will return . Even worse, I cannot extract the first column using X = record[:, 0]. Is there a way to efficiently load list(or any other types) from binary file into a normal numpy array?
Suppose we have a DataFrame, with multiple columns in which one column contains the list of values as a value, we need to extract all the values of the list and add each of these values into a separate new row.Converting column with list of values into rowsFor this purpose,...

In order to convert PySpark column to Python List you need to first select the column and perform the collect() on the DataFrame. By default, PySpark
With two-dimensional arrays, the first index specifies the row of the array and the second index 对于二维数组,第一个索引指定数组的行,第二个索引指定行 specifies the column of the array. 指定数组的列。 This is exactly the way we would index elements of a matrix in linear algebra. 这正是...
