Please uninstall the python you installed, and reinstall lumerical package: unintal first, restart the computer, and sometimes you may need a clean installation. please refer “clean installation”  https://optics.ansys.com/hc/en-us/articles/5613618572947-Fixing-installation-or-license-activation-issues
