[data_format = "timescale" # "local_db" or "timescale"](https://github.com/assume-framework/assume/blob/79d7c749aef0664aba4ba2d5340f906d03457f24/examples/examples.py#L75-L82) here is a test problem comment @Manish-Khanra

@nick-harder Hi Nick, Could you please run the example_04_base_case_steel_plant_2019, and check whats the issue? I am getting the below error with our new update: RuntimeWarning: invalid value encountered in cast new_result = trans(result).astype(dtype)

@Manish-Khanra works fine for me! I would suggest to complete delete the folder local_db and try again. this error looks like it is cming from writing data at some point

@nick-harder also tried deleting the folder, still getting the same error.

@Manish-Khanra now I am getting the following error: File "/Users/nick/GitHub/assume/assume/units/steel_plant.py", line 414, in calculate_marginal_cost +value(self.components["electrolyser"].b.electrolyser_operating_cost[t]) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "pyomo/core/expr/numvalue.pyx", line 229, in pyomo.core.expr.numvalue.value File "pyomo/core/expr/numvalue.pyx", line 215, in pyomo.core.expr.numvalue.value ValueError: No value for uninitialized NumericValue object electrolyser_operating_cost[0]

could you please take a look at it and let me know when it's fixed. I will look into your other issue further afterwards. thanks!

This error stems from the same issue. The previous error message occured when I have commented out marginal cost function. This error message is when I have again included the marginal cost function. I suspect this error is related to the sequencing of the pyomo components while creating an instance of a model called 'model_opt'. Could figure out the solution yet
