# Quick examples to convert numpy array to dataframe # Example 1: Convert 2-dimensional NumPy array array = np.array([['Spark', 20000, 1000], ['PySpark', 25000, 2300], ['Python', 22000, 12000]]) df = pd.DataFrame({'Course': array[:, 0], 'Fee': array[:, 1], 'Discount': ...
The.to_records()method can be used to convert a DataFrame to a structured NumPy array, retaining index and column labels as attributes. The.valuesattribute also converts a DataFrame to a NumPy array but is less preferred than.to_numpy()due to potential dtype inconsistencies. The DataFrame’s ...

MapType and ArrayType of nested StructType are only supported when using PyArrow 2.0.0 and above. StructType is represented as a pandas.DataFrame instead of pandas.Series.Convert PySpark DataFrames to and from pandas DataFramesArrow is available as an optimization when converting a PySpark DataFrame...
