my env Linux mint 21 Python 3.10.11

Running the following 2 lines of code generates error:

import chromadb client = chromadb.PersistentClient(path="./tmp_dir")

generates the following error AttributeError: type object 'hnswlib.Index' has no attribute 'file_handle_count'

here is the full error report
