[USER (data scientist)]: Great! Now, I've got another dataframe updated_odds_df with updated odds for each match. Please note that it has 'Match ID', 'Updated Odd_1', and 'Updated Odd_2' columns. Can we merge it with the original dataset? Please generate the code with the output in dataframe type.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd
import numpy as np
import pickle
from decision_company import read_csv_file, check_elements_in_list, join_dataframes, sum_up, use_function

# Load the dataset 
atp_tennis = read_csv_file('atp_tennis.csv')

# YOUR SOLUTION BEGIN:
<code1>
[GENERATE YOUR CODE] 
</code1>
# YOUR SOLUTION END

print(later_rounds_odds)

# save data
pickle.dump(later_rounds_odds,open("./pred_result/later_rounds_odds.pkl","wb"))

---END CODE TEMPLATE---

[YOU (AI assistant)]: Sure thing! Here's the code to merge the datasets using the 'Match ID' column:
