也是看别人代码才知道可以打开一个文件就可以把多个对象序列化到这个文件中。
with open('../raw_data/remap.pkl', 'wb') as f:
pickle.dump(reviews_df, f, pickle.HIGHEST_PROTOCOL) # uid, iid
pickle.dump(cate_list, f, pickle.HIGHEST_PROTOCOL) # cid of iid line
pickle.dump((user_count, item_count, cate_count, example_count),
f, pickle.HIGHEST_PROTOCOL)
pickle.dump((asin_key, cate_key, revi_key), f, pickle.HIGHEST_PROTOCOL)
with open('../raw_data/remap.pkl', 'rb') as f:
reviews_df = pickle.load(f)
cate_list = pickle.load(f)
user_count, item_count, cate_count, example_count = pickle.load(f)
