Customizing Vectordb Bench breaks installation

[nsai1]

Hello,

I am trying to customize my index creation in the pgvector.py code.
When i build my code with pip install -e '.[pgvector]' the build completes successfully.

Successfully built vectordb-bench
Installing collected packages: vectordb-bench
Successfully installed vectordb-bench-0.0.17.dev0+g1ab46dd.d20241118 

But when I run the vectordbbench --help command I get the following error

File "/usr/local/bin/vectordbbench", line 5, in <module> 
     from vectordb_bench.cli.vectordbbench import cli
File "/VectorDBBench/vectordb_bench/cli/vectordbbench.py", line 1, in <module> 
     from ..backend.clients.pgvector.cli import PgVectorHNSW
File "/VectorDBBench/vectordb_bench/backend/clients/pgvector/cli.py", line 9, in <module> 
     from ....cli.cli import (
File "/VectorDBBench/vectordb_bench/cli/cli.py", line 22, in <module> 
     from .. import config
 ImportError: cannot import name 'config' from 'vectordb_bench' (unknown location) 

This happens even if i build an unchanged repo with the pip install -e '.[pgvector]' command.
