	# The first import (of discretisedfield) on Windows produces a failure in the notebook tests
	# (output mismatch) because of some (hidden) message on stderr (some IO error on Windows that
	# does not seem to have an actual effect). By importing it once prior to the actual tests
	# this can be circumvented.
	# It appears to be package-independent (so just a problem with the first import statement).
	# As we see the failure from a cell that imports discretisedfield we do the same import here.
