~Update: 本文提的 Issue 在 huggingface-hub 的main分支已解决，暂未发版，大家可以手动安装main分支版本。~

huggingface-hub 目前对于 HF_ENDPOINT 的支持存在几个 bug，已经给官方提了 issue，在修复前，先记录下临时解决方案。

这些bug为什么值得写一篇记录？

已经给官方提了 issue 和部分解决方案。由于我开设了一个 hf-mirror.com 对 HF_ENDPOINT 依赖很强，最近经常有用户来反馈这几个问题，因此在官方修复前，需给出一些临时解决方案。

此外，令人担忧的是，官方可能对于这几个 bug 的修复没有特别大的动力（个人不负责任的推测）。根据官方这个 PR，由于关闭了 Private Hub 实验，后续不再主动宣传 HF_ENDPOINT 变量了，基于这种策略，虽然官方声称该变量目前仍然保持有效，但对其的支持可能会逐渐 broken，例如我目前在最新版的 transformers、datasets 中遇到的，我估计就和这个策略有关（毕竟文档都不主动介绍了，新来的程序员不了解的话，就容易忽略这个变量）。

问题1：无法上传文件

Github Issue Link
问题复现方法：如下，我们用 huggingface-cli 的 upload 子命令进行项目的上传，将当前目录内的所有文件上传到远程仓库的项目根目录：

$ export HF_ENDPOINT=https://hf-mirror.com
$ huggingface-cli upload --token hf_*** username/reponame . .
Consider using hf_transfer for faster uploads. This solution comes with some limitations. See https://huggingface.co/docs/huggingface_hub/hf_transfer for more details.

    return fn(*args, **kwargs)
  File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_api.py", line 3370, in create_repo
    return RepoUrl(d["url"], endpoint=self.endpoint)
  File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_api.py", line 437, in __init__
    repo_type, namespace, repo_name = repo_type_and_id_from_hf_id(self, hub_url=self.endpoint)
  File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_api.py", line 227, in repo_type_and_id_from_hf_id
    raise ValueError(f"Unable to retrieve user and repo ID from the passed HF ID: {hf_id}")
ValueError: Unable to retrieve user and repo ID from the passed HF ID: https://huggingface.co/username/reponame

可以看到存在报错，报错显示连接的仍然是 https://huggingface.co 而非用 HF_ENDPOINT 设置的 https://hf-mirror.com。

值得注意的是，如果设置的 HF_ENDPOINT="https://huggingface.co"，则不会存在以上问题。

问题1的临时解决办法：

使用Python代码HfApi.upload还是可已上传的：

import os
os.environ['HF_ENDPOINT']='https://hf-mirror.com'

import huggingface_hub
huggingface_hub.login("hf_***")

from huggingface_hub import HfApi
api=HfApi()
api.upload_folder(
    repo_id="username/reponame",
    folder_path="/path/to/your/repo",
    path_in_repo="."
)

问题2：无法下载特定数据集

Github Issue Link
该 Issue 需要同时满足以下三个条件才会触发：

• datasets>2.15.0 或 huggingface-hub>0.19.4，这很常见，两者最新版本就可以触发
• 数据集的 ID 不包含机构名, 例如 bookcorpus, gsm8k, wikipedia, 而非 A/B 形式的数据集 ID.
• 设置了 HF_ENDPOINT 且其值的格式不是 (hub-ci.)?huggingface.co 该格式。

复现步骤：

1.安装特定版本（当前最新版本）的库

pip install datasets==2.18.0
pip install huggingface_hub==0.21.4

2.执行以下python代码

import os
os.environ['HF_ENDPOINT'] = 'https://hf-mirror.com'
from datasets import load_dataset
bookcorpus = load_dataset('bookcorpus', split='train')

输出如下：

问题2的临时解决方法

降级版本，至少是下述及以下的版本号：

pip install datasets==2.15.0

或

pip install huggingface-hub==0.19.4
