ModuleNotFoundError: No module named 'wfdb'

I upgraded a new version of Streamlit today and when I started my project. There was an issue about “ModuleNotFoundError: No module named ‘wfdb’”. Can you help me fix the issue? Or is it possible to downgrade to the previous version?

Traceback:

File "C:\Users\abc\anaconda3\envs\abc\lib\site-packages\streamlit\script_runner.py", line 354, in _run_script exec(code, module.__dict__)
File "C:\Users\abc\testsite.py", line 3, in <module>
    import wfdb

Many thanks!

PS: I think the newest version that I have, is 1.1.0.
