在jupyter笔记本中自动缓存pandas读取的文件？

import pandas as pd
import os

def check_cache(file_path):
    cache_dir = './cache'
    if not os.path.exists(cache_dir):
        os.makedirs(cache_dir)
    
    cache_file = os.path.join(cache_dir, file_path.replace('/', '_') + '.pkl')
    
    if os.path.exists(cache_file):
        return pd.read_pickle(cache_file)
    else:
        return None

def read_file(file_path):
    cached_data = check_cache(file_path)
    
    if cached_data is not None:
        return cached_data
    
    data = pd.read_csv(file_path)
    data.to_pickle('./cache/' + file_path.replace('/', '_') + '.pkl')
    
    return data

file_path = 'path/to/file.csv'
data = read_file(file_path)
