Errors on Python 3.9 - Githubissues

Thanks for your reply. Please see attached. It's very long, not sure I captured it all but I think the log output repeats itself continuously.

Hello @yoeldk https://github.com/yoeldk!

What types of error? Can you share the stacktrace?

If you don't know where the object of type `builtins.function` is coming
from, try looking at the hash chain below for an object that you do recognize,
then pass that to `hash_funcs` instead:

Object of type builtins.function: <function start_haystack at 0x00000230CD078E50>


Please see the `hash_funcs` [documentation]
(https://docs.streamlit.io/library/advanced-features/caching#the-hash_funcs-parameter)
for more details.

While caching the body of `start_haystack()`, Streamlit encountered an
object of type `builtins.function`, which it does not know how to hash.

**In this specific case, it's very likely you found a Streamlit bug so please
[file a bug report here.]
(https://github.com/streamlit/streamlit/issues/new/choose)**

In the meantime, you can try bypassing this error by registering a custom
hash function via the `hash_funcs` keyword in @st.cache(). For example:
