Issue with python code used for correlation (person) using databricks.

This is what I'm receiving:

**I have to use df = spark.read.format("csv").option("header", "False").load **

CODE

import pandas as pd

## DataFrameReader

df = spark.read.format("csv").option("header", "False").load("dbfs:/FileStore/tables/users_no_labels.txt").toPandas()

##find correlation

correlation = df.corr(method = 'pearson')

##to display full correlation dataframe

with pd.option_context('display.max_rows', None, 'display.max_columns', None):

print(correlation)
