I'm trying to get an Impact Matrix in Climada from an impact object using the below codes:

Calculating impact matrix for present

from climada.engine import Impact

imp1 = Impact()

imp1.calc(exp, imp_set_xlsx, ts_fl, save_mat=True)

When I tried to print the impact matrix << print( imp1.mat)) >>, I received the following error:

ValueError: Attribute imp_mat is empty. Recalculate Impactinstance with parameter save_mat=True.

However, I made sure save_mat is set True.

In CLIMADA the impact matrix is accessed as imp1.imp_mat (c.f. the documentation https://climada-python.readthedocs.io/en/stable/tutorial/climada_engine_Impact.html )

Please note also that with the latest release 3.3 the impact computation has been modified. Now, there are two classes, ImpactCalc and Impact.

Your code would then read

from climada.engine import Impact, ImpactCalc

impcalc = ImpactCalc(exp, imp_set_xlsx, ts_fl)
imp1 = impcacl.impact(save_mat=True)
print(imp1.imp_mat))
