Improve impact calc error messages when there is a mismatch of impf ids between exposures and impfset #863

luseverin · 2024-03-22T16:51:29Z

Changes proposed in this PR:

Add a test in ImpactCalc.impact(exposures, impfset, hazard) to handle AttributeError arising when an impact function id contained in the exposures has no matching impact function in the impact function set.
Change previous AttributeError: 'list' has no attribute 'calc_mdr' to a more explanatory error message

This PR fixes #669 (reopened)

Thanks for the quick fix! I have some very small style requests.

Also, please do not forget to complete the changelog and to add yourself to the author's list

Please use the similar variable names as in the rest of the file: if -> impf.

Besides, a variable name if is rather confusing as this is also a python operator. Note that we had a longer discussion on that 2 years ago when we decided to avoid the variable name if.

Thanks for the notice, I changed if_id to impf_id.

If being pedantic, I would improve slightly the test by having two impact functions in the set, one that is in the exposures, and one that isn't.

Ok so now the test considers the case of having two impact functions in the exposures (impf ids 1 and 2), and two impact functions in the impfset (impf ids 1 and 3), so that an error is raised as there is no impact function with id 2 in the impfset. Let me know in case you meant something else.

The linter should complain that these lines are too long. Could you please shorten them?

Sorry I might have missed this. I think it is good now.

Thanks for the review! I think I have adressed all your comments. I also modified the author's list and changelog. Let me know if there's anything else.

+        impf_exp = ImpactFunc()
+        impf_exp.id = 1
+        impf_exp.intensity = np.array([0, 20])
+        impf_exp.paa = np.array([0, 1])
+        impf_exp.mdd = np.array([0, 0.5])

This should work too right? Ideally, one does not first initiate an object and then modify its attributes. This is mostly a Matlab-style remnant in older CLIMADA code.

Suggested change

impf_exp = ImpactFunc()

impf_exp.id = 1

impf_exp.intensity = np.array([0, 20])

impf_exp.paa = np.array([0, 1])

impf_exp.mdd = np.array([0, 0.5])

impf_exp.haz_type = 'TC'

impf_noexp = deepcopy(impf_exp)

impf_noexp.id = 3

impf_exp = ImpactFunc(haz_type='TC', id=1)

impf_noexp = deepcopy(impf_exp)

impf_noexp.id = 3

Yes that's indeed better, thanks for the suggestion!

Sorry, I did not see that first. For the unit test, please use self.assertRaises() : https://docs.python.org/2/library/unittest.html#unittest.TestCase.assertRaises

Yes that makes sense to use this instead. I modified the testing function.

Great, that's even better this way! I have included this modification in my last commits.

Yes that is more readable, I also included this. Thanks!

The compatibility test with petals is failing, but I think it is unrelated to this PR. @emanuel-schmid @luseverin are we ready to merge?

luseverin · 2024-04-08T14:11:21Z

It also does not seem to me that the tests failing are related to the PR. So ready to merge from my side.
