ERROR 1148 (42000): The used command is not allowed with this MySQL version

mysql数据库将文件内容加载到表中报错：

mysql> LOAD DATA LOCAL INFILE '/path/pet.txt' INTO TABLE pet
       LINES TERMINATED BY '\r\n';

ERROR 1148: The used command is not allowed with this MySQL version
出现这个错误的原因是：If LOAD DATA LOCAL is disabled, either in the server or the client, a client that attempts to issue such a statement receives the following error message:

ERROR 1148: The used command is not allowed with this MySQL version
可见，出于安全考虑，默认是不允许从client host远程通过load data命令导数据的。

解决方案：
两个步骤：

SET GLOBAL local_infile=1；

连接数据库时

mysql -u Name -p --local-infile=1;

使用时

  conn = pymysql.connect(host="localhost",
                           user="root",
                           password="111",
                           db="work2forecast",
                           charset="utf8mb4",
                           local_infile=1)
