python - 导入 matplotlib 或 seaborn 时出现 ModuleNotFoundError

问题描述

我试图在 Jupyter Notebook 上的 Iris 数据集中执行 EDA，我试图导入这些库，但我一直遇到这个错误。请帮忙。我已经pip install --upgrade pip在我的 Anaconda 命令提示符中尝试过，它会回复我

已满足要求：c:\users\aarushi\anaconda3\lib\site-packages (21.2.4) 中的 pip

我也试过pip install Pillow，但它的回应是

已满足要求：c:\users\aarushi\anaconda3\lib\site-packages (8.3.1) 中的枕头

也试过pip install --upgrade pip了，反应-

已满足要求：c:\users\aarushi\anaconda3\lib\site-packages (21.2.4) 中的 pip

我还在我的系统上安装了 IntelliJ、Visual Studio、Weka。这是我的代码-

import matplotlib
import seaborn as sns

解决方案

是的，我也遇到了这个错误。jupyter notebook打开后你安装seaborn了吗？您应该从顶部菜单 Kernel > Restart kernel 重新启动内核。
