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具有冲突名称的模块（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 prediction package in your examples directory.
在你的情况下，我怀疑有一个名为prediction.py的文件，你得到的不是你的examples目录中的预测包。
