flair根：[Errno 13]权限被拒绝：‘/PermissionError/.cache’

Question

我使用www-data用户(没有sudo权限)使用flair包调用python脚本。模型位于用户具有访问权限的路径中，我已经设置了flair.cache_root = Path("tools/flair")

但是，当我使用该用户运行脚本时，我得到一个权限错误：

PermissionError: [Errno 13] Permission denied: '/root/.cache'\

我可以避免使用/root/.cache吗？我不想编辑该目录的读写权限。如果我以root身份运行该脚本，它可以正常工作。如何以其他用户的身份运行它？我在Ubuntu上运行它。

该错误是由flair加载的转换器模型引起的。还必须通过设置环境变量TRANSFORMERS_CACHE=/path/to/transformers来指定转换器的缓存目录
