# HF-to-wisemodel/从Huggingface上拉取模型、数据集等到wisemodel

# 这是一个示例Space,实际使用请参考下面说明，先Duplicate一个私有的space

- 这个space可以把已经发布在Huggingface上的模型拉取到wisemodel上。
- This space uploads model from Huggingface to wisemodel.

- **请确认您是repo的拥有者或者有权限操作！**
- **Please make sure that you're the owner of the repo or have permission from the owner to do so!**


# 如何使用这个空间？
# How to use this Space?

- 点击右上角settings后面的“…”按钮，选择“Duplicate this Space”创建一个私有的space，同时输入wisemodel的token(必填)、wisemodel的用户名（GIT_USER 必填）、wisemodel的注册邮箱（GIT_EMAIL 必填），确保有相应repo写入的权限。你还需要输入你的git用户名和邮箱。
- Duplicate this Space and providing WiseModel token (mandatory) and your read/write HF token (mandatory).you also need to provide your git username and email to push the model to WiseModel.

- 在wiseModel上创建一个空的repo，这一步需要手动完成，Space不会为您创建一个空的repo。
- Create your target model repo on WiseModel. This step is not automated.

- 在刚刚自己创建的私有space里填写相应的信息，wisemodel的git clone链接，以及Huggingface的repo名称。
- In your own private Space, fill in information below.

- 点击submit按钮，然后可以通过logs按钮查看进度。
- Click submit then watch for output in container log for progress.
