阅读原文时间:2023年07月11日阅读:2

https://www.kaggle.com 的官方 API ,可使用 Python 3 中实现的命令行工具访问。

Beta 版 - Kaggle 保留修改当前提供的 API 功能的权利。

重要提示:使用 1.5.0 之前的 API 版本提交的比赛可能无法正常工作。如果您在提交竞赛时遇到困难,请使用 来检查您的版本kaggle --version。如果低于 1.5.0,请更新pip install kaggle --upgrade.

一、安装Kaggle环境并配置

1.1 安装Kaggle Package

确保您安装了 Python 3 和包管理pip器。

运行以下命令以使用命令行访问 Kaggle API:

pip install kaggle(您可能需要pip install --user kaggle在 Mac/Linux 上执行。如果在安装过程中出现问题,建议这样做。)sudo pip install kaggle除非您了解自己在做什么,否则通过 root 用户(即)完成的安装将无法正常工作。即便如此,它们仍然可能不起作用。如果出现权限错误,强烈建议用户安装。

您现在可以使用kaggle以下示例中所示的命令。

如果遇到kaggle: command not found错误,请确保您的 Python 二进制文件在您的路径上。您可以kaggle通过执行pip uninstall kaggle并查看二进制文件的位置来查看安装位置。对于 Linux 上的本地用户安装,默认位置是~/.local/bin. 在 Windows 上,默认位置是$PYTHON_HOME/Scripts.

重要提示:我们不提供 Python 2 支持。在报告任何问题之前,请确保您使用的是 Python 3。

1.2 API Token配置

要使用 Kaggle API,请在https://www.kaggle.com注册一个 Kaggle 帐户。

注册成功后登录kaggle

  • 点击右上角头像处,会弹出相关侧边栏设置,如下

  • 点击Your Profile,进入设置

  • 在上面的页面找到API对应的设置,点击Create New Token,这将触发下载包含您的 API 凭据的文件kaggle.json。对应的kagge.json如下

kaggle配置

本机安装kaggle api

pip install kaggle

将此文件放在该位置~/.kaggle/kaggle.json

若没有这个目录,则在根目录下创建.kaggle文件夹,再把kaggle.json放入

cd ~
mkdir .kaggle
cd ~/.kaggle/

(在 Windows 上的该位置C:\Users<Windows-username>\.kaggle\kaggle.json- 您可以检查确切位置,无驱动器,使用echo %HOMEPATH%)。您可以定义一个 shell 环境变量KAGGLE_CONFIG_DIR来将此位置更改为$KAGGLE_CONFIG_DIR/kaggle.json(在 Windows 上为%KAGGLE_CONFIG_DIR%\kaggle.json)。

为了您的安全,请确保您计算机的其他用户对您的凭据没有读取权限。在基于 Unix 的系统上,您可以使用以下命令执行此操作:

chmod 600 ~/.kaggle/kaggle.json

您还可以选择将您的 Kaggle 用户名和令牌导出到环境中:

导出KAGGLE_USERNAME=datadinosaur
导出KAGGLE_KEY=xxxxxxxxxxxxxx

此外,您可以导出通常采用$HOME/.kaggle/kaggle.json“KAGGLE_”格式(注意大写)的任何其他配置值。

例如,如果文件具有变量“proxy”,您将导出KAGGLE_PROXY 并由客户端查看。

二、Kaggle Command命令使用

命令行工具支持以下命令:

kaggle competitions {list, files, download, submit, submissions, leaderboard}
kaggle datasets {list, files, download, create, version, init}
kaggle kernels {list, init, push, pull, output, status}
kaggle config {view, set, unset}

有关使用这些命令中的每一个,请参阅下面的更多详细信息。
