If they need to use something from another package, then they should refer to them globally with from os import path and let python work out where that is with $PATHand $PYTHONPATHWhen you use python -m package.test_A.test, then using from ..A import foo resolves just fine because it...

importsys sys.path.append('/path/to/module')importmodule_name 1. 2. 3. 4. 5. 通过将指定的路径添加到sys.path中,然后使用import语句来引入模块,就可以从指定路径中引入模块了。 示例 假设我们有以下目录结构: AI检测代码解析 - my_project
刚才的两个文件同属于一个包下同一级别,结构如下左图,我们来看看不同包下同一级别的情况,见右图,使用B1.py访问A包下的A1.py 这时直接执行以下三种代码会遇到相同的错误:attempted relative import with no known parent package 这时无论我们添加sys.path.append(".")("..")("./A")("./A/A")都无济于...
importing a module : loads the contents creates anamespacecontaining the contents 怎么找module e.g.foo.bar.baz In this case, Python first tries to importfoo, thenfoo.bar, and finallyfoo.bar.baz. 寻找顺序: sys.modules 是个dict sys.meta_path ...
import arcpy arcpy.env.workspace = <path to workspace as a string> arcpy.env.overwriteOutput = True <path to workspace as a string>将替换为工作空间的实际路径。 使用Python窗口时,导入和环境由ArcGIS Pro控制,这意味着不需要这些行。 但是,Python编辑器中的独立脚本(如 IDLE 和 PyCharm)需要使用导入和...
ImportError: attempted relative import with no known parent package 当前执行入口.py文件不支持相对导入 ValueError: attempted relative import beyond top-level package 顶层文件夹不能作为包,进行导入 还有几点注意事项 1.pycharm的优化 pycharm会把项目的根目录添加到sys.path!
