You can use the os.chroot to change the root directory of the current process to path. We can also import the module by first converting the directory where it exists as python package. project_root = os.path.dirname (os.path.dirname (__file__)) output_path = os.path.join (project_root, 'subfolder1') The project_root is set to the folder above your script's parent folder, which matches your description. Example END To work with directories and files in Python, use the built-in os module. When we add the file __init__.py we tell python that the directory is a package. The __init__.py file contains the contents of the package when it's treated as a module. It takes only a single argument as a new directory path. The basic workaround here is to mark lr_utils.py folder as Sources Root by right click in the Project window.
