Description

This PR is to replace the use of assert np.allclose in testing with np.testing.assert_allclose. The testing version checks that shapes are equal, where np.allclose allows broadcasting before testing values (see #380).

• Replace calls in test_*.py files and import np.testing.assert_allclose.
• "Fix" issues where previously passing tests now fail due to differences in default permitted tolerances. This PR does not change any of the package code, so no calculations differ: it is simply differences in the permitted tolerance and we accepted the values before.
• Look at the new fails where the shape is not as expected and np.allclose let it pass.

Fixes #380 (issue)

Type of change

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist

• Make sure you've run the pre-commit checks: $ pre-commit run -a
• All tests pass: $ poetry run pytest

Further checks

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works
