Exiobase hybrid 3导入丢失的JSON数据包

Question

使用以下包版本:

bw2data 4.0.dev18

bw2io 0.9.dev10

以下代码:

import bw2io as bi
ebhyb3 = bi.Exiobase3HybridImporter(dirpath_ebhyb3, db_name='EXIOBASE 3.3.17 hybrid')

输出以下错误:

---------------------------------------------------------------------------

根据https://presamples.readthedocs.io/_/downloads/en/stable/pdf/:

datapackage.json: A JSON file following the datpackage standard with the metadata for these presamples. This is the only file that is required for a presample directory.

这个JSON应该包含什么信息，它是否在某处可用?

您需要首先使用这里的代码将exiobase (hybrid units) version 3.3.17转换为导入器所期望的格式。然后您可以运行导入器。

from bw2io.importers.exiobase3_hybrid import Exiobase3HybridImporter
ei = Exiobase3HybridImporter(path_to_exiobase)
