Cache_data with function to load gif files

[Junior19]

Before my question, I want to greet and thank all the Streamlit team for having developed this wonderful tool (seriously, thank you !).

I am new and I still don’t understand the cache function. From what I saw, it serves to execute a function only once, as long as the input parameters do not change, which saves time in the execution. However, I’m trying to use it in a small test app, specifically to load two .gif files that weigh less than 10 mb each, but I feel that even though the function in which both files are loaded is cached, on each interaction, both files are reloaded (because of the delay). Am I using the cache function wrong or is it not really used for this?

Thanks for any help.

import streamlit as st
import base64
import time

st.set_page_config(page_title = "JARU Apps", page_icon = "🦅", layout = "wide")

@st.cache_data
def load_gif():
    file_1   = open(r'SearchIT.gif', "rb")
    content1 = file_1.read()
    gif1     = base64.b64encode(content1).decode("utf-8")
    file_1.close()
    file_2   = open(r'Creator.gif', "rb")
    content2 = file_2.read()
    gif2     = base64.b64encode(content2).decode("utf-8")
    file_2.close()
    return gif1, gif2

gif1, gif2 = load_gif()

col1, col2 = st.columns([1, 1])
with col1:
    col3, col4, col5 = st.columns([1, 2.1, 1])
    with col4:
        st.markdown('#')
        st.header('SearchIT y Creator')
        st.text_input('Usuario:', placeholder = 'Ingrese aqui su usuario')
        st.text_input('Contraseña:', type = "password", placeholder = 'Ingrese aqui su contraseña')

        button_1 = st.button('Ingresar', use_container_width = True)
        empty_1  = st.empty()
        if button_1:
            with empty_1.container():
                st.warning('Las credencialas ingresadas no son correctas. Porfavor, reviselas e intente denuevo.')
                time.sleep(2.5)
                empty_1.empty()
        st.markdown('''<marquee style='font-size: 2; width: 100%' scrollamount='10'>

    if selectbox_1 == 'App SearchIT':
        st.subheader('App.SearchIT')
        st.markdown('''<div style="text-align: justify;">

Hi @Junior19 , i think your using the cache_function wrong u have to give any function parameter for your load_gif() function so that stream lit can hash and store it in the cache , so just give any parameter that doesn’t change everytime the code is reloaded and keep in mind u cant give the image as a parameter to hash .
Hope this helps
