network.optimize_investment(invest_options=invest_opt) #136

Hi all, I am here with the issue related to the optimization. I tried to run the examples provided, and got the KeyError like this: 'Index \'("<dhnx.optimization.oemof_heatpipe.HeatPipeline: Label(tag1=\'infrastructure\', tag2=\'heat\', tag3=\'pipe-typ-A\', tag4=\'forks-2-forks-3\')>", "<oemof.solph.buses._bus.Bus: Label(tag1=\'infrastructure\', tag2=\'heat\', tag3=\'bus\', tag4=\'forks-3\')>")\' is not valid for indexed component \'InvestmentFlowBlock.invest\'' In every optimization examples where network.optimize_investment(invest_options=invest_opt) commad is to be run, I am getting the same kind of error. Can anyone check if these examples (introduction.py,minimal_network.py,invest_with_existing.py,..) are still running or suggest me some ideas if one encountered similar issue before? It would be super helpful. Thanks! image

Regards, Bishal

Dear Bishal, thank you for your issue. At the moment due to the latest oemof-solph major release, DHNx needs to be updated and released as well. In the meanwhile, please try to use the dev branch or install an oemf-solph version < 0.5, so 4.5 for example.

Hi @joroeder

when i execute network.optimize_investment(invest_options=invest_opt)

i get the following error: TypeError: Node.init() got an unexpected keyword argument 'heat_loss_factor'

Does this also has something to do with the latest update of oemof-solph?

Best regards, Orcun

It's been a while, but I hope the answer still helps: This was due to an update of oemof.network (and rather sloppy handling of keyword arguments here at DHNx). It should be fixed in the dev branch of DHNx.
