Hi @ncbperera , it seems the folder directory you're giving SingleOutputEcospold2Importer isn't valid (e.g., you're using a mix of back and forward-slashes, among others). Try giving it a valid one and it should work.

@romainsacchi ,

Even i hardcode the path as below it gives the same error

path_dir_datasets_ecoinvent: str = ' C:/Users/charithap/data/data_raw/ecoinvent_3.9.1_cutoff_ecoSpold02/datasets'

ValueError Traceback (most recent call last) Cell In[24], line 32 28 bw2data.projects.set_current(str_ecoinvent_version) 29 #bw2io.bw2setup() ---> 32 importer: SingleOutputEcospold2Importer = bw2io.SingleOutputEcospold2Importer( 33 dirpath = path_dir_datasets_ecoinvent, 34 db_name = str_ecoinvent_version 35 )
