        Dear firedrake manager, I failed to install the firedrake even though I reinstalled python latest and firedrake. python3 and firedrake seem to run well. But when I ran "the Simple Helmholtz equation" on introductory tutorials, "NameError: name 'UnitSquareMesh' is not defined" appeared. Would you help me? Thank you for the help you can provide.
