我想在我的系统上删除并重新安装 fenics 软件。按照这，我尝试仅删除 fenics（因为我不确定如果删除依赖包会发生什么）
sudo apt-get remove fenics
但是当我转到我的 ipython3 /python3 控制台并执行from fenics import *进一步输入时DOLFIN_EPS，我仍然得到输出，就好像 fenics 根本没有被卸载一样。
当我再次运行该命令时sudo apt-get remove fenics，我收到以下消息：

Package 'fenics' is not installed, so not removed

Use 'sudo apt autoremove' to remove them.

如前所述，我不知道 autoremove 是否会删除我用于其他工具的库，我不想执行该命令。
有人知道可能出了什么问题吗？
边注：我想进行全新安装，因为我需要将 matplotlib 从版本 1.3.1 更新到版本 3.0.3，之后 fenics 无法正常工作。
任何帮助都值得感激。谢谢
