python3 chat.py Error

[MichiScotsguard]

I got these errors when executing chat.py with python3. What do I do?

Traceback (most recent call last): File "/home/kali/Downloads/tools/AutoGDB/chat.py", line 1, in from src.utils import cli File "/home/kali/Downloads/tools/AutoGDB/src/utils.py", line 1, in from autogdb import * File "/home/kali/Downloads/tools/AutoGDB/autogdb/init.py", line 1, in from .models import * File "/home/kali/Downloads/tools/AutoGDB/autogdb/models.py", line 7, in from langchain.agents import Tool ModuleNotFoundError: No module named 'langchain'
