升级anaconda中python到3.10版本的简单步骤
作者：Oo_Amy_oO
anaconda是一个非常好用的python发行版本,其中包含了大部分常用的库,下面这篇文章主要给大家介绍了关于升级anaconda中python到3.10版本的简单步骤,需要的朋友可以参考下
需要使用函数pairwise，发现python版本偏低，尝试了把anaconda中jupyter notebook中的python环境升级到3.10。
步骤如下：
在Anaconda Prompt中依次执行以下命令：
# 更新conda环境 conda update conda # 更新anaconda环境 conda update anaconda
为了避免对现有环境产生影响，创建一个新的虚拟环境安装python3.10。执行以下命令创建一个名为python3.10的虚拟环境：
# 创建环境 conda create -n python3.10 python=3.10 # 激活虚拟环境 conda activate python3.10
安装Python3.10
# 安装python3.10 conda install python=3.10 # 激活3.10版本 conda activate python=3.10
在base下查看当前conda环境配置
conda info --envs
如果显示python3.10环境，那么python3.10就安装成功了。
回到anaconda要在左侧list中的environment环境中进行配置，将之前的环境更换为python3.10，就可以使用了。
附：Anaconda创建python3.10环境 ，pip报错：ImportError: DLL load failed while importing _ctypes: 找不到指定的模块。

二、解决方案
conda install python=3.10
