Some tests fail on Mac M3 due to float64 not being supported on MPS #507
Description
When I run the unit tests on either the dev or main branch, two tests fail on my local machine (an Apple Silicon M.3 Macbook) due to this error:
FAILED tests/test_integration.py::test_auxilliary_cli - TypeError: Cannot convert a MPS Tensor to float64 dtype as the MPS framework doesn't support float64. Please use float32 instead.
FAILED tests/unit_tests/test_runner.py::test_initialize_model - TypeError: Cannot convert a MPS Tensor to float64 dtype as the MPS framework doesn't support float64. Please use float32 instead.
When running unit tests all Tensors should be on the CPU, so I suspect this is stemming from a tensor not being moved to the correct device.
