vscode中PyLint报错Unable to import解决方案

在导入其它文件夹中py文件的时候，即使在代码中添加了指定路径，由于Pylint 无法检测到该文件，会给出Unable to import 'xxx'的错误提示

需要在项目目录下添加.pylintrc文件指定要引用文件所在的目录

# .pylintrc 文件用于为pllint进行自定义配置

[MASTER]
# XXX 应被替换为你指定的文件夹如(./custom_lib)
init-hook='base_dir="XXX"; import sys,os,re; _re=re.search(r".+\/" + base_dir, os.getcwd()); project_dir = _re.group() if _re else os.path.join(os.getcwd(), base_dir); sys.path.append(project_dir)'
