使用conda create -e test2创建环境test2
python -m import numpy numpy.__file__ -> /home/xx/.local/lib/python3.8/site-packages/numpy/__init__.py
which pip -> /usr/bin/pip
使用conda create -n test3 python=3.8创建环境test3

在这里面pip和python38都被安装了
之后which pip -> /home/xx/anaconda3/envs/test3/bin/pip
先pip uninstall numpy这里卸载位于系统.local/lib/python3.8/site-packages/numpy中的numpy，然后使用pip install numpy，这时候，numpy安装在/home/xx/anaconda3/envs/test3/lib/python3.8/site-packages/numpy/__init__.py。
使用conda create -n test,python版本是3.8，但是这里不会在lib里安装pip和python38。如果使用conda install numpy，则会安装python3.11和pip。也意味着python被更新了

解决方法：
以后重建一个python的版本，python3.9。以后都使用python3.9
删除老的环境：
conda env remove -n test
conda env remove -n test2
conda env remove -n test3
conda env remove -n ttseg
conda env remove -n py38base
conda env remove -n py39test
创建ttsegpy39环境
conda create -n ttsegpy39 python=3.9
conda info -e
conda activate ttsegpy39
pip list
接着pip install totalsegmentator,
