I have version 0047.4 running on both, Win7 and mac, machines.
I was able to successfully deploy the DataExplorer app on heroku by commenting out the @st.cache decorator.
Commenting out the decorator on macos allows me to load the data and see the dataframe but then I get:


TypeError : ‘ellipsis’ object is not iterable*

Also, it is strange that this line of code:
st.subheader(f'Map of all pickups at {hour_to_filter}:00)
works perfectly in Windows but when I run it on the macos I get an ‘invalid syntax’, “unxpected token ‘)’” and an “undefined variable ‘f’” errors.
