天赋权限错误：[Errno 13] 权限被拒绝：'/root/.cache'

如何解决天赋权限错误：[Errno 13] 权限被拒绝：'/root/.cache'

我使用 flair 用户（无 www-data 权限）调用带有 sudo 包的 python 脚本。模型位于该用户具有访问权限的路径中，我已将其设置为 flair.cache_root = Path("tools/flair")

但是，当我使用该用户运行脚本时，出现权限错误：

tagger = MultiTagger.load([\\\"flair/ner-german-large\\\",\\\"de-pos\\\"])\
File \\\"/usr/local/lib/python3.7/dist-packages/flair/models/sequence_tagger_model.py\\\",line 1330,in load\

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 的身份运行脚本，它可以正常工作。我如何以其他用户身份运行它？我在 Ubuntu 上运行它。

解决方法

错误是由 flair 加载的转换器模型引起的。必须通过设置环境变量 TRANSFORMERS_CACHE=/path/to/transformers

额外指定转换器的缓存目录
