Kaggle API使用教程
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}
