step:
git clone https://github.com/zilliztech/VectorDBBench.git
cd VectorDBBench
pip install -e ".[test]"
init_bench

Reproduce the failure using the listed clone, installation, and init_bench steps. Read backend/task_runner.py around _pre_run and init_db, then inspect backend/clients/milvus/milvus.py around collection index creation and the COSINE dataset configuration. Done means the Cohere Milvus case initializes and runs without the metric-type error.
