converting python file to exe file

Question

i have a python file that converts pdf files to excel files from the same folder as the python file exists. here is the code :

import os
import pandas as pd
from PyPDF2 import PdfReader
from tabula.io import read_pdf

def pdf_to_excel(pdf_file):
    # Use PdfReader to open the PDF file
    with open(pdf_file, 'rb') as file:
        pdf_reader = PdfReader(file)
        
        # Initialize an empty list to store DataFrames
        all_tables = []
        
        # Iterate through pages and extract tables
        for page_number in range(len(pdf_reader.pages)):
            # Check if the page contains tables using tabula
            tables = read_pdf(pdf_file, pages=page_number+1, multiple_tables=True)
            
            # Convert each table to a DataFrame and append to the list
            for table in tables:
                df = pd.DataFrame(table)
                all_tables.append(df)
                
        # Concatenate all DataFrames into a single DataFrame
        final_df = pd.concat(all_tables, ignore_index=True)
        
        # Save the final DataFrame to a single Excel file
        excel_file = os.path.splitext(pdf_file)[0] + "_merged_tables.xlsx"
        final_df.to_excel(excel_file, index=False)
        print(f"All tables merged and saved to {excel_file}")

if __name__ == "__main__":
    # Get the list of PDF files in the same folder
    pdf_files = [file for file in os.listdir() if file.lower().endswith('.pdf')]

    if not pdf_files:
        print("No PDF files found in the folder.")
    else:
        for pdf_file in pdf_files:
            pdf_to_excel(pdf_file)

input("Press Enter to exit...")

I have converted it to an exe file because the client hasn't python installed in his pc, so i used pyinstaller : pip install pyinstaller pyinstaller --onefile code.py but when i ran the exe file it shows me an error :
