I got the same error

i'm facing the same issue. It should be a problem of inconsistent engineering paths. try modify lightrag.py

#line 70-81

return import_class()   #add ()

## #add path lightrag
Neo4JStorage = lazy_external_import("lightrag.kg.neo4j_impl", "Neo4JStorage") 
OracleKVStorage = lazy_external_import("lightrag.kg.oracle_impl", "OracleKVStorage") 
OracleGraphStorage = lazy_external_import("lightrag.kg.oracle_impl", "OracleGraphStorage") 
OracleVectorDBStorage = lazy_external_import("lightrag.kg.oracle_impl", "OracleVectorDBStorage") 
MilvusVectorDBStorge = lazy_external_import("lightrag.kg.milvus_impl", "MilvusVectorDBStorge") 
MongoKVStorage = lazy_external_import("lightrag.kg.mongo_impl", "MongoKVStorage") 
ChromaVectorDBStorage = lazy_external_import("lightrag.kg.chroma_impl", "ChromaVectorDBStorage") 
TiDBKVStorage = lazy_external_import("lightrag.kg.tidb_impl", "TiDBKVStorage") 
TiDBVectorDBStorage = lazy_external_import("lightrag.kg.tidb_impl", "TiDBVectorDBStorage")

After I made the change like this, it started running.

[GreenerZ]

ChromaVectorDBStorage = lazy_external_import("lightrag.kg.chroma_impl", "ChromaVectorDBStorage") 
TiDBKVStorage = lazy_external_import("lightrag.kg.tidb_impl", "TiDBKVStorage") 
TiDBVectorDBStorage = lazy_external_import("lightrag.kg.tidb_impl", "TiDBVectorDBStorage")

No need to add these, this is a feature submitted in the new version. Just add the ”lightrag“ before ".kg" on your own version.

@GreenerZ

Can you tell me if adding the

ChromaVectorDBStorage = lazy_external_import("lightrag.kg.chroma_impl", "ChromaVectorDBStorage") 
TiDBKVStorage = lazy_external_import("lightrag.kg.tidb_impl", "TiDBKVStorage") 
TiDBVectorDBStorage = lazy_external_import("lightrag.kg.tidb_impl", "TiDBVectorDBStorage")

fixes this?

Note that you need to add () after "import_class" in line 63
