上下文版本冲突错误,Google colab

Par*_*Pal 7 google-colaboratory

我正在尝试在 Google colab 上安装并运行 sunpy。它需要 astropy 版本 3.1 或更高版本的软件包。即使在安装 astropy 版本 3.2.1 后,当我导入 sunpy 时,它也会出现以下错误:

pip list 给出以下结果:

如何解决这个问题?

astropy >= 3.1像sunpy之前一样手动安装:

!pip install astropy>=3.1
!pip install sunpy

然后,使用“运行时”->“重新启动运行时”菜单重新启动运行时以获取新的 astropy。最后导入sunpy.
