使用飞桨paddlenlp的Taskflow API报错 RuntimeError: C:\Users\*** mkdir failed!
在github提出issues后，开发者很友好的帮助解决了这个问题。
为paddlenlp的工作人员点个赞！
执行代码如下
from paddlenlp import Taskflow
tag = Taskflow("pos_tagging")
不光是pos_tagging，其它Taskflow的任务如word_segmentation、ner等也不能使用。
报错如下

RuntimeError: C:\Users\***(中文) mkdir failed!
关键是RuntimeError: C:\Users\***(中文) mkdir failed!
这里看下你的用户名是不是中文
win11创建用户，用户名输入中文后的痛苦！
解决方法
tag = Taskflow("pos_tagging", home_path="xxxx")
手动指定home_path，然后就可以成功运行了。
