I'm trying to scale some data from a csv file. I'm doing this with pyspark to obtain the dataframe and sklearn for the scale part. Here is the code:
from sklearn import preprocessing
import numpy as np
import pyspark
from pysparl.sql import SparkSession
spark = SparkSession.builder.getOrCreate()
df = spark.read.option('header','true').csv('flights,csv')
X_scaled = preprocessing.scale(df)
If I make the dataframe with pandas the scale part doesn't have any problems, but with spark I get this error:
ValueError: setting an array element with a sequence.
So I'm guessing that the element types are different between pandas and pyspark, but how can I work with pyspark to do the scale?

sklearn works with pandas dataframe. So you have to convert spark dataframe to pandas dataframe.
X_scaled = preprocessing.scale(df.toPandas())
