Python3 relative import IDE - Debug/Run issues

Issues with relative imports when using python3

In the same folder I have

package1.py

```

def hello_import():
    print('hello_import')

```

package2.py

```

from .package1 import hello_import


def use_package1():
    hello_import()


if __name__ == '__main__':
    use_package1()

```

If I use "from .package1 import hello_import" the IDE recognizes the package and the import, but I get 
ModuleNotFoundError: No module named '__main__.package1' error when trying to debug or run the code

If I use "from package1 import hello_import" (without the period before the package name) the IDE does not recognizes the package and the import,
but now the  Debug/Run works well.

I can do

```

try:
    from .package1 import hello_import
except Exception as e:
    from package1 import hello_import


def use_package1():
    hello_import()


if __name__ == '__main__':
    use_package1()

```

but this does not look to me as a professional solution.   
Any suggestions on how to solve this?

I am using:   

• Python 3.6.4
• pycharm pro 2020.2
• linux

thanks
