【 python version : 3.9.13+vscode】环境搭建以及报错解决学习（一）

1、anaconda 环境的选择,新建，与查看

创建	conda create -n test1 python=3.9
查看	conda env list
激活	activate torch
退出	conda deactivate
删除在base环境下删除	conda remove -n test1 --all

操作如下：

(base) C:\Users\Administrator>conda info -e

2、文件读取，要用到绝对路径

D:\Machine-Learning-master\Decision Tree\lenses.txt
#打开的文件名
filename = “D:\Machine-Learning-master\Machine-Learning-master\kNN\2.海伦约会\datingTestSet.txt”

3、多个环境

import os
os.environ[“KMP_DUPLICATE_LIB_OK”] = “TRUE”

4、报错Import “sklearn.externals.six” could not be resolvedPylancereportMissingImports

#from sklearn.externals.six import StringIO
from six import StringIO##修改

5、FontProperties=font 报错，拼写错误

改为： fontproperties=font

6、中文文本分割

可以直接使用第三方分词组件，即jieba，没错就是"结巴"。

pip3 install jieba
