Hello, i get this error when launching test_base_scenario.py . Here is the full traceback :

Thanks and good work.

Dear Lucien, I was not able to reproduce your error. Did you clone or download the repo? I just cloned the repo and ran the test_base_scenario.py in the dev branch and it worked for me. Otherwise, maybe checkout the master branch and try again.

Feel free to reach out again if it's still not working.

Cheers

Pyosch,

First thanks for sharing some great content. I did get the same error as Lucien after cloning the dev branch. Haven't tried the master branch since it was 137 commits behind the dev branch.

Traceback (most recent call last): File "test_base_scenario.py", line 412, in net_dict = operator.run_base_scenario(baseload) File "<>\vpplib\vpplib\operator.py", line 320, in run_base_scenario res_loads.loc[idx][bus].item() AttributeError: 'float' object has no attribute 'item'.

Best,

SB

Hi Zypher,

ok, I'll have a look at it again and try to fix the issue. It might take a while though. Maybe try the master branch as well for the time being.

Thanks for your interest in my library :)

Cheers Pyosch

Hi, found a quick fix for this issue by commenting out the item()-function in line 316-320.

state_of_charge, res_load = self.virtual_power_plant.components[ self.net.storage.loc[storage_at_bus].name.item() ].operate_storage( res_loads.loc[idx][bus] # .item() )

Cheers Norman

Hey Norman,

thanks for your contribution! I am currently working on updating the library, unfortunately pvlib pushed an update in the meantime too, which I have to take care of for everything to work. Hope I can deliver soon though.

Cheers Pyosch

Hey everyone,

I pushed changes to the dev branch (Yes, a lot). I included the bugfix of Norman (thanks again!) and hopefully it works for everyone now. If not, let me know. I will then also update the master and make a new release.

Cheers Pyosch
