wurst's Issues

Get region codes

REGIONS = [(row, ws.cell(row=row, column=2).value) for row in range(5, 47)]

Brian found an error, it is taking the data until line 45 (index 46) missing the last line of the data with RoW. So it should be 47 instead of 46 in the line of code.

ecoinvent filters for oil electricity have to exclude nuclear

the current oil electricity filters have to exclude nuclear, because 'boiling water reactor' is also selected here.

oil_open_cycle_electricity = [
contains('name', 'oil'),
contains('name', 'electricity'),
equals('unit', 'kilowatt hour'),
exclude(contains('name', 'combined cycle')),
]

oil_combined_cycle_electricity = [
contains('name', 'oil'),
contains('name', 'electricity'),
equals('unit', 'kilowatt hour'),
contains('name', 'combined cycle'),
]

oil_chp_electricity = [
contains('name', 'oil'),
contains('name', 'heat and power'),
equals('unit', 'kilowatt hour'),
]

NoResults: No suitable production exchanges founds

Hello all,

I am trying to link and save an excel database, but I am getting an error (screenshot attached). Could you please let me know what might be the possibility for the error to occur?

Thank you!

gas open cycle electricity filter uses combined cycle

the gas open cycle and biomass CHP filters both have _combined_cycle in them, which causes them to not work.

keyerror with copy_to_new_location

I tried to test the copy_to_new_location function but I got a keyerror message. The code was the following

import wurst as w
boiler_ch=w.get_one(db,
                     w.searching.contains('name', 'light fuel oil'),
                     w.searching.contains('name', '10kW condensing'),
                     w.searching.equals('location', 'CH'),
                    )
boiler_qc=w.copy_to_new_location(boiler_ch,'CA-QC')

db is a version of ecoinvent 3.3 cutoff. get_one correctly identifies the activity , but I get a couple of messages (one an error) when executing copy_to_new_location

Successfully switched activity dataset to new code c9cc73b5becb4509804660ec8abf00e9
KeyError: 'exchanges'

I am using the following versions: wurst==0.1.dev2; brightway2==2.1.1

please let me know if you prefer that I post it as a question in stackoverflow instead opening an issue here.

Documentation should be explicit that exactly one reference product is assumed

At least, by the Brightway2 exporter, which calls in order:

• link_internal
• reference_product

which raises an error.

parameter keys are different when exporting

here is the current code:
'parameters': {key: value['amount'] for key, value in proxy.data.get('parameters', {}).items()}

This means that in an unimported ecoinvent I would access the efficiency value with something like:

ds['parameters']['efficiency']['amount']

but if I export with wurst, I have to access the same parameter with:

ds['parameters']['efficiency']

function empty_high_voltage_markets needs to also remove imports

The function empty_high_voltage_markets should also delete all imports of electricity.

I have written my own function to delete all electricity inputs (except own consumption). it looks like this and seems to work:

def delete_electricity_inputs_from_market(ds):
    # This function reads through an electricity market dataset and deletes all electricity inputs that are not    
    # own consumption. 
    ds['exchanges'] = list(get_many(
        ds['exchanges'], 
        either(
            exclude(contains('unit', 'kilowatt hour')),
            contains('name', 'market for electricity, high voltage'),
            contains('name', 'market for electricity, medium voltage'),
            contains('name', 'market for electricity, low voltage'),
            contains('name', 'electricity voltage transformation')
        )
    ))
    return ds

Is wurst incompatible with ecoinvent 3.4?

When trying one of the example notebooks, I ran into issues when using ecoinvent 3.4. Is wurst compatible with ecoinvent 3.4?

data = w.extract_brightway2_databases(["ecoinvent 3.4 cutoff"])

AttributeError: 'list' object has no attribute 'items'

Inconsistency between `name` and `activity`

In the current schema, an activity has the field name in its metadata, but this same field is called activity in the exchange metadata. We can call it name in both cases - this decreases cognitive load and unpleasant surprises.

Need parameters (efficiency) in database extract

Hi Chris,

We need the efficiency parameter extracted with the database!

I have found (so far) three different ways that the efficiency parameter could be labelled:

['parameters']['efficiency']['amount']
['parameters']['efficiency_oil_country']['amount']
['parameters']['efficiency_electrical']['amount']

Sometimes it's also hidden in the comments section, but there isn't much we can do about that...

Thanks,

Brian

empty file wurst/ecoinvent/__init___.py leads to error: "ImportError: cannot import name 'ECOINVENT_ORDERED_GEO' from 'wurst.ecoinvent'"

Trying to execute the marginal mixes wurst notebook example but got an error
ImportError: cannot import name 'ECOINVENT_ORDERED_GEO' from 'wurst.ecoinvent'

I see also that others have encountered the same issue. I contacted Laurant Vandepaer, who has no solution.

It seems that the wurst/ecoinvent/init_.py file is empty as per 28 sept 2017. I found the previuos file version in the commit history. copied the lines of code into my local init_.py file to resolve the issue.

I wanted to share this workaround in case others might be interested. I am new to github, and don't know how to contribute this? hence i made this post. Is it correct understood that I should make a "pull request" for the commit of 28 sept 2017, which deleted all lines of code from the init_.py file? I cant figure out how to do this :-)

Best regards, Simon

example for change_exchanges_by_constant_factor() wrong

Hi Chris, the example for the above mentioned function is wrong. You have filters for biosphere and technosphere exchanges, but you are using 'name' as the key instead of 'activity'.
