Any idea on this error: ModuleNotFoundError: No module named '_strategy' ?

[phizaz]

  File "main.py", line 72, in func
    import strategy
  File "C:\Users\user\notebooks\dqn-connect4\strategy.py", line 17, in <module>
    _strategy = swig_import_helper()
  File "C:\Users\user\notebooks\dqn-connect4\strategy.py", line 16, in swig_import_helper
    return importlib.import_module('_strategy')
  File "C:\Users\user\Anaconda3\lib\importlib\__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
ModuleNotFoundError: No module named '_strategy'

Do I have to install anything else beside cloning the repo?
