Use a different hashing algorithm: The crc32 function may not be suitable for generating unique hash values. You can try using a different hashing algorithm such as SHA-256 or MD5. These algorithms are designed to generate unique hash values for different inputs. UUID3 and UUID5 in Pyth...

train_click=pd.read_csv('/home/xiaoguzai/数据/新闻推荐/train_click_log.csv') 得到train_click的dataframe 然后首先获得click中col的数组以及对应的数组长度,这里进入label_enc函数 uniq,nuniq=click[col].unique(),click[col].nunique() 得到uniq的数组以及数组长度 ...
