Python module import works for one file, crashing for another

I have a very strange problem. I have three files, the first contains a base class from which classes in two other files are inherited.

The strange thing: yesterday everything went well, but today one of the files no longer works. In the meantime, I did not touch on imports.

.
└── orangecontrib
    ├──__init__.py
    └── prototypes
        ├──__init__.py
        └── widgets
            ├──__init__.py
            ├── owpythagorastree.py
            ├── owclassificationpythagorastree.py
            └── owregressionpythagorastree.py

So, the classification and regression classes must be inherited from the base class, and the import is performed in exactly the same way:

owclassificationpythagorastree.py

...
from orangecontrib.prototypes.widgets.owpythagorastree import OWPythagorasTree
...

owregressionpythagorastree.py

...
from orangecontrib.prototypes.widgets.owpythagorastree import OWPythagorasTree
...

However, when I try to run two scripts from the command line (using python owregressionpythagorastree.py), the regression widget works fine, but the classification widget causes the following error:

Traceback ( ): "owclassificationpythagorastree.py", 6,     from orangecontrib.prototypes.widgets.owpythagorastree import OWPythagorasTree ImportError: 'orangecontrib.prototypes'
