在上安装GDAL

Question

我在上安装GDAL有困难。当我跑步时：

!pip install gdal

我得到以下错误

Collecting gdal

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-umhRKK/gdal/

同样的事情也适用于：

!pip install gdal==2.2

或者：

!pip install python-gdal

还有我尝试过的其他一些类似的命令。我发现的用于更新安装工具的修补程序在更新后仍然会给我带来这个问题。有什么问题吗？

Answer 1

根据如何向添加Python库上的Datalab文档，您可以遵循三种方法在Cloud中安装第三方库：

1. 使用!pip install lib-name。这显然不适用于您，即使是通过应用您在四处查看后发现的一些故障排除修补程序。
2. 使用下面# Option 2中的代码指定要在Datalab实例的启动脚本中运行的命令，然后继续重新启动它。
3. 使用从Datalab Docker容器继承的您自己的Docker自定义容器。我知道这个选项是最复杂的，但是对于需要更灵活定制的包来说，它可能是最合适的选项，比如您遇到问题的gdal包。

在备选案文2中使用的脚本：

#Option 2
%%bash
echo "pip install lib-name" >> /content/datalab/.config/startup.sh
cat /content/datalab/.config/startup.sh
