Load a png image to a Streamlit web app

[yazidsaissi]

Hi,

I'm using Streamlit to create a web app and I want to load a png image from a managed folder into my app (without using PIL module)

Does anyone have an idea about how to do it ?

Thanks

Hi, 

If the goal is to display an image located in the managed folder in the streamlit webapp, then you can use Dataiku Managed Folders API and BytesIO. Please refer to the example below:

import streamlit as st
import pandas as pd
import numpy as np
import altair as alt
import dataiku
import io

st.title('Hello Streamlit!')

folder_handle = dataiku.Folder("OZG8yjfI")  # replace ID with your managed folder
myfile = "dataiku-logo.jpeg"  # replace with your file name and path in folder

with folder_handle.get_download_stream(myfile) as io_stream:
    img = io.BytesIO(io_stream.data)
    st.image(img, channels="RGB")

Result:

but it is similar to using the PIL.

from PIL import Image
with folder_handle.get_download_stream(myfile) as io_stream:
    image = Image.open(io_stream)
    st.image(image, channels="RGB")

You still need some library to read from the "download_stream", so I'm not sure I fully understood the issue and the goal.

If the above is not what you were looking for, please provide more details on what is the issue and what is the goal.

Best,

Vitaliy
