提问by Hello lad
I have a project having the structure
我有一个具有结构的项目
/example
../prediction
....__init__.py
....a.py
PYTHONPATH is pointed to /example
PYTHONPATH 指向 /example
now I open the python in terminal and type
现在我在终端中打开 python 并输入
import prediction
it succeeded, but if I type
它成功了，但如果我输入
import prediction.a
it returns error
它返回错误
ImportError: No module named 'prediction.a'; 'prediction' is not a package
why is that? isn't that already imported as a package
这是为什么？不是已经作为包导入了吗

The behavior you are seeing can be caused if there is a module (foo.py) or package (foo/__init__.py) in your current directory that has a conflicting name.
如果当前目录中存在名称冲突的模块 ( foo.py) 或包 ( foo/__init__.py)，则可能会导致您看到的行为。
In your case, I suspect there is a file named prediction.py, and you're getting that instead of the predictionpackage in your examplesdirectory.
在您的情况下，我怀疑有一个名为 的文件prediction.py，并且您正在获取该文件而不是目录中的prediction包examples。
