Covid Streamlit example Demo

Hello everybody,

Using my time during the confinement to discover Data Science, I wrote my first Streamlit app to share my tests on this page :[http://ml.madpowah.org] . It’s just a little app to follow the Covid particularly in France but I added the rest of the world. I tried to test prediction with the ARIMA model and to create a DB stored on MongoDB scrapping french site to propose a Sentiment Analysis.

I’m really impressed by the ease of use of the API and little stuff like the progress bar which provide a really look nice.

Hello @cloud, welcome to the forum !

Would love to check your app (because…well I live in France ahah) but got the Firefox T-rex

Oh strange, I just tried without problem. The redirection 80->8501 worked looking your screen. Maybe have you got a proxy blocking the 8501 port ?

Yeah you’re right, firewall acting weird, works well XD thx

@cloud Nice app! Even with very poor French, I can follow the app and the conclusions, which is great :slight_smile: Also I haven’t seen an app doing sentiment analysis before on covid hashtags, that was interesting.

One small layout point. In the Sentiment Analysis Test I at first thought that it wasn’t working because everything I was entering was ‘Sentiment : Positif’ which is the default. To make it clearer you could have put that in Markdown with the phrase I entered above so that it says "Sentiment for is Positive,’ that way it would be clear that it ran every time.

@Amanda_Kelly Thank you very much for your feedback. I’m totally agree, I have changed like you said and I think it’s clearer. By default, if the size of the input is 0, the answer is now different.
Thank you again.

Hello, congratulations on the app, could you share the code?

Thank you @Meiker_Lazo_Colonio. Maybe I’ll share it later when I’ll have more time but you can already find a big part of the code (different analysis and prediction) on my blog : http://blog.madpowah.org

Thanks you @cloud.

@cloud could you share source code. I’m also working on some dashboard which needs multiple pages. Couldn’t figure out how it would work. It’d be a great help. Thanks :slight_smile:

Hello @sahil,

Just like that

def main():
    page = st.sidebar.selectbox("Menu",["Etat actuel en France", "Etat actuel dans le monde"])

    if page == "Etat actuel en France":
        loadFrance()
    elif page == "Etat actuel dans le monde":
        loadMonde()

def loadFrance():
.....
def loadMonde():
.....
