[USER (data scientist)]: I've got this dataset called "high_credit_long_duration" and I need to find clients with multiple existing credits and high installment commitments. Can you help me out? Please generate and display a dataframe of the subset of customers from the 'credit_customers' dataset who have multiple existing credits and high installment commitments.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd 
import pickle
 
# Load the dataset 
credit_customers = pd.read_csv("credit_customers.csv") 
 
# YOUR SOLUTION BEGIN:
<code1>
[COMPLETE YOUR CODE]
</code1>
# YOUR SOLUTION END

print(f"multiple_credits_high_commitment: {multiple_credits_high_commitment}") 

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

---END CODE TEMPLATE---
