I want to import ecoinvent 3.6 is a database in my brightway2 project. I have downloaded the required ecospold data files from Ecoinvent, however I get the following error:
fpei36 = r"C:~\ecoinvent_36_cut-off_lci_ecoSpold02.7z" # name of path
ei36 = bw.SingleOutputEcospold2Importer(fpei36, 'ecoinvent 3.6 cutoff')
Traceback (most recent call last):
File "", line 1, in ei36 = bw.SingleOutputEcospold2Importer(fpei36, 'ecoinvent 3.6 cutoff')
File "~\Anaconda\lib\site-packages\bw2io\importers\ecospold2.py", line 67, in init self.data = extractor.extract(dirpath, db_name, use_mp=use_mp)

File "~\Anaconda\lib\multiprocessing\pool.py", line 657, in get raise self._value
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbc in position 2: invalid start byte
I would not know 1) what is wrong and b) how I can fix what is going wrong.
Thanks for your help!
You are passing the path to a zip (.7z) file. The dirpath argument should instead be the path to a directory with the files contained in the zip file.
To get going, simply unzip the file first, and then change your code to fpei36 = r"C:~\path_to_dir_with_thousands_of_ecospold_files"
You can unzip the file in Python, see here for example. You can also simply unzip it using a tool such as this before you get coding.
