Is there a way to change the placeholder text of a spinner in streamlit?

Question

I would like to change the placeholder text displayed when calling a function:

I tried using

with st.spinner(text="Fetching measures"):
    measures = fetch_measures(userid, start_ts, end_ts)

but it just adds a new warning above with “Fetching measures”. Is there a way to just change the text “Running function_name(…)”?

Answer 1

There is a way as found on the Streamlit's forum:

@st.cache(show_spinner=False)
def fetch_measures():
    # do stuff
    time.sleep(10)


def main():
    with st.spinner(text="Fetching measures"):
        measures = fetch_measures()

if __name__ == "__main__":
    main()

Just add show_spinner=False inside the st.cache() decorator to remove the warning. Then, add your own warning with with st.spinner(text="Fetching measures").
