When trying to run a Python script in PyCharm via a run configuration, you might hit an error like this:
Traceback (most recent call last): File ".../__main__.py", line 3, in <module> from ... ImportError: attempted relative import with no known parent package Process finished with exit code 1
You might be able to resolve this by setting up the PyCharm run configuration as a “Module name” rather than a “Script path”.
Go to the run configuration drop down menu and click “Edit Configurations…”
At the top left of the “Configuration” tab there’s a label that says “Script path” with a drop-down arrow next to it. Click on that and select “Module name”.
Enter the Python module name that you would use to run this on the command line
With a bit of luck this will let you run the module in PyCharm with the benefit of the various IDE tools such as the Python debugger.
