Hello, I work with Patrick Farrell and he sent me a code to run in firedrake. I installed it on my ubuntu system using the instructions on your website, installing it in a python virtual environment (unsetting my environmental variable $PETSC_DIR to do this as it came up with a warning about that). The installation seemed to work, but when I test the installation I get errors. Terminal output pasted below. Is this something to do with having the virtual environment and where it is trying to access python/petsc? How should I fix it? Many thanks for your help in advance.
