Hey @iamchoudhari11,
First, welcome to the Streamlit Community! 
In your requirements.txt you have a lot of (94!!) specific packages including streamlit==0.69 which is a very old version, we are currently on 0.82. In Streamlit 0.69 the st.set_page_config was still in beta. 
I would recommend upgrading to a newer version of streamlit. If for some reason you can’t do this (again HIGHLY recommend that you do) in version 0.69 the call for setting the page config is st.beta_set_page_config
I also think you should remove any of those packages from your requirements.txt that you don’t specifically use in your app. Checkout this link to know why:
Happy Streamlit-ing!
