Google colaboratory 使用 kaggle，服务器版本 1.5.6，客户端版本 1.5.4，升级失败

Question

我想在 google colaboratory 中使用 kaggle API。安装的客户端是1.5.4，服务器是1.5.6。通过pip运行安装升级kaggle后，系统仍然调用1.5.4版本

我尝试使用 pip 安装和升级 kaggle 包。不工作。我也尝试重新启动会话/运行时。

!pip install kaggle/pip install kaggle --upgrade

Kaggle API 1.5.4

啊，这确实是一种奇怪的状态。

修复：!pip install --upgrade --force-reinstall --no-deps kaggle

根本问题：我们同时安装 py2 和 py3 包，并且（由于历史原因）第二个安装 py2 包。 kaggle 是 kaggle python 包安装的包装器；由于我们第二次使用 py2，因此 py2 包装器位于 /usr/local/bin 中，并且恰好是旧版本。
