无法验证和序列化来自 pyshacl 的新推断图

Question

我遇到了一个问题，我需要你的帮助。我正在研究 pyshacl 验证，这是一个 Python 库，用于根据 SHACL 图验证 RDF 图。我有一个 shacl 形状图，它有一个 SPARQL 构造子句来创建新实例并将它们与其他实例链接。然后我想用现有数据序列化它们并制作一个新图。但是当我运行验证时，它成功了，没有任何输出。我不知道出了什么问题。此外，当我在 GraphDB 查询编辑器上运行相同的查询时，它会显示可能的结果。谁能帮我解决这个错误？

from rdflib import *
from pyshacl import validate

ontology = Graph().parse("./graphs/DMN-RDF-Dicon-OCQA-Tbox.ttl",
                             format="ttl")
example_building = Graph().parse("./graphs/Duplex_A_20110505_LBD.ttl",
                                     format="ttl")

combined_graph = ontology + example_building  # Combine the graphs
rules_graph = Graph().parse("testing.ttl",
                                format="ttl")  # Load the SHACL rules graph

# Validate the combined graph and apply the rules
conforms, inferred_graph, string = validate(combined_graph, shacl_graph=rules_graph,
                                            data_graph_format='turtle', shacl_graph_format='turtle',
                                            debug=True, advanced=True, inplace=True)

# Merge the original graph with the inferred graph
new_graph = combined_graph + inferred_graph

# Save the new graph to a new file
new_graph.serialize(
        destination="Inferred_geometry_inspections.ttl", format="ttl")

这是我的规则图：（删除前缀，因为它们很多）
