FileNotFoundError: [Errno 2] No such file or directory: 'streamlit'

My python version is 3.11, trulens-eval version 0.22.2, I actually have streamlit (version 1.31.1)
I see the logging db(default.sqlite) in my local directory but no any .streamlit folder
I tried different trulens-eval version down to 0.19.2 but the problem remains

@julfr - can you share more about the environment you're running in or the OS?

@joshreini1
I am facing the same issue. Actually I can see both .sqllite and .streamlit at current path (also validated with sys.path).

Here is my environment

• Ubuntu 22.04
• Python 3.10
• trulens_eval 0.25.1
• streamlit (installed) 1.32.1
