TypeError:在使用pyrdf2vec时，字节索引必须是整数或片，而不是str

Question

我是Python和这个库的新手，我应该如何修复它？它可以与一些sparql端点pint（如DBPdeia）一起使用，但与Yago一起，它会遇到此错误

from pyrdf2vec.graphs import KG
import pandas as pd
import rdflib as rdflib
from pyrdf2vec import RDF2VecTransformer
from pyrdf2vec.walkers import RandomWalker
import numpy as np

wiki_data = pd.read_csv('wiki.csv')
entities = wiki_data['WikiSub']

label_predicates = [
'http://schema.org/actor',]

kg = KG("https://yago-knowledge.org/sparql", is_remote=True,
       label_predicates=[rdflib.URIRef(x) for x in label_predicates])

transformer = RDF2VecTransformer(walkers=[RandomWalker(2, 5)])

walk_embeddings = transformer.fit(kg, entities, verbose=True).transform(
    entities
)
