pyinstaller creating a package more than a GB for a simple python script having import pandas, and some operations

When I run pyinstaller for such a simple script sam.py as below, the package size is worth 1.6 GB...How do we justify sharing this big file to someone ? Is it normal ?

import pandas as pdd = pd.read_csv("~/a.csv")cols = ['a', 'b']d[cols].to_csv("~/new.csv", index = False)

Package size1.6G    _internal48M    sam

The package was generated with the spec file with the command pyinstaller sam.spec where the spec file was generated using pyinstaller sam.py and later edited to increase recursion limit to resolve related issues

# -*- mode: python ; coding: utf-8 -*-import syssys.setrecursionlimit(5000)  # Increase recursion limit

The _internal package shows the following large files:
