Jupyter notebook下载python包问题

1.问题过程描述

重新安装了下anaconda不知道哪个步骤有个bug，导致我使用如下魔法命令安装相应的包却无法安装成功(以前是可以正常安装的）

!pip install tensorflow-gpu

其出现的结果显示如下：

Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
Requirement already satisfied: matplotlib in d:\anaconda\lib\site-packages (3.8.0)
Requirement already satisfied: contourpy>=1.0.1 in d:\anaconda\lib\site-packages (from matplotlib) (1.2.0)
Requirement already satisfied: cycler>=0.10 in d:\anaconda\lib\site-packages (from matplotlib) (0.11.0)
Requirement already satisfied: fonttools>=4.22.0 in d:\anaconda\lib\site-packages (from matplotlib) (4.25.0)
Requirement already satisfied: kiwisolver>=1.0.1 in d:\anaconda\lib\site-packages (from matplotlib) (1.4.4)
Requirement already satisfied: numpy<2,>=1.21 in d:\anaconda\lib\site-packages (from matplotlib) (1.26.4)
Requirement already satisfied: packaging>=20.0 in d:\anaconda\lib\site-packages (from matplotlib) (23.1)
Requirement already satisfied: pillow>=6.2.0 in d:\anaconda\lib\site-packages (from matplotlib) (10.2.0)
Requirement already satisfied: pyparsing>=2.3.1 in d:\anaconda\lib\site-packages (from matplotlib) (3.0.9)
Requirement already satisfied: python-dateutil>=2.7 in d:\anaconda\lib\site-packages (from matplotlib) (2.8.2)
Requirement already satisfied: six>=1.5 in d:\anaconda\lib\site-packages (from python-dateutil>=2.7->matplotlib) (1.16.0)

只说了条件满足，但他就是不给我下载，我在我的cmd终端是可以正常下载的。

随后我也检查了当前文件的python解释器路径和该文件所处的虚拟环境的python解释器路径发现是相同的！

#检查当前.ipy文件路径运行的python解释器路径
import sys
print(sys.executable)

#该项目所处的虚拟环境查找python解释器路径

#激活虚拟环境
conda activate tensorflow

#查看 python 解释器路径
python -c "import sys; print(sys.executable)"

 2.解决方法

%pip install matplotlib

使用这个魔法命令即可正常安装
