            Python: Parsing List of lists
            Asked 2022-Mar-31 at 17:38

            In Python I'm attempting to create a login page that draws stored data from a Google Sheet for use in Streamlit Authenticator. Streamlit Authenticator authenticates logins by accessing a list container with usernames, passwords, and screen names, as below:



            Answered 2022-Mar-31 at 17:38

            This is because your username is a list of lists, not a list of strings.

            All you need to do is extract the string from the inner list.



            How to save DataFrame as csv in streamlit?

            Answered 2022-Mar-29 at 10:58

            You need to use st.download_button

            For streamlit > 1.0.0

            Display a download button widget.

            This is useful when you would like to provide a way for your users to download a file directly from your app.

            Note that the data to be downloaded is stored in-memory while the user is connected, so it's a good idea to keep file sizes under a couple hundred megabytes to conserve memory.

            A working example can be found here

            In your case

            Images not loading when deploying streamlit app on GCP
            Asked 2022-Mar-26 at 14:24

            I created a streamlit app for data science. The user uploads an image and gets an output with an image displayed, but after deploying the app I'm getting zero rather than an image.

            Solved by transforming the image (OpenCV, pillow ...) into bytes



            Cannot display SHAP text visualization in Streamlit
            Asked 2022-Mar-15 at 23:58

            I am trying to build a dashboard of my NLP project. So I am using a BERT model for the predictions, the SHAP package for the visualization and Streamlit for creating dashboard:



            Answered 2021-Dec-10 at 05:15

            This can be visualized with Streamlit Components and latest SHAP v0.36+ (which define a new getjs method), to plot JS SHAP plots

            (some plots like summary_plot are actually Matplotlib and can be plotted with st.pyplot)



            How to populate a streamlit selectbox with vlaues from a SQL query
            Asked 2022-Feb-17 at 21:42

            The goal is to have a streamlit selectbox show a list of pairs coming from the symbol column from the database.



            Answered 2022-Feb-17 at 21:42

            You have to pass a sequence to a selectbox and each element of that sequence will be shown as a possible element to select. I assume what you are passing is pair = 'BNBBTC'. This means every character becomes one value you could choose. However, what you have to pass to your select box would be choices = ['ETHBTC', 'LTCBTC', 'BNBBTC'].

            As fetchall returns a list of tuples, you can get that as options = [row[0] for row in cursor.fetchall()] and finally do st.sidebar.selectbox('Select symbol', options)

            Streamlit how to display buttons in a single line

            Due to page reload, the video uploaded sing st.file_uploader() in streamlit is lost. How to retain it?
            Asked 2022-Jan-23 at 13:08

            I have a streamlit app with sidebar, which consists of a radio button with 2 values: A & B. Both A & B uses st.file_uploadeer() to upload videos to the app. However, when I switch between A & B, the uploaded videos get lost due to page reload. How can I retain the uploaded video unless the user specifically changes the uploaded file? I think it can be done using session states or on_change() callback of the st.file_uploader() function, but I'm not able to figure out how to do it.

            Loop Directory (folder and Subfolder in Python app)
            Asked 2022-Jan-15 at 21:44

            I am trying to have an app that loops through a directory (folder and sub) searching for multiple extensions or keywords and outputs the list in a dynamic frame but the code (or returns Zero if nothing found).

            Current code fails both when multiple extensions (or keywords) are inputted or fails by grouping multiple results in a single row of the frame.

            I need help in debugging my code posted below.

            Thank you



            Answered 2022-Jan-15 at 21:44

            There are some problems in your code:

            1. When getting the extension using st.text_input the returned value is a string not a list of extension. In order to solve this just ask the user to enter the extension seperated with a comma and split the string to get a list of extensions.
