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

Question

我正在调用带有 flair 程序包的 python 脚本和 www-data 用户（无 sudo 权限）。这些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，当我运行与该用户的脚本时，我收到权限错误：

我可以避免使用 /root/.cache 吗？我不想编辑那个目录的读写权限。如果我运行脚本作为 root 它工作正常。我如何运行它作为其他用户？我运行在 Ubuntu 上发布它。

错误是由flair加载的变压器模型引起的。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

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

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

python

read-write

flair
