I am new to streamlit. I was trying to setup a simple annotation process for a pet project. So, I have all the filenames stored in a pandas dataframe. Now, the annotation process is supposed to have this flow: Iterate over the files Read an image. Display it Annotate using radio boxes. Increment t…

I recommend this thread that was motivated by a similar use case. Maybe you can find an answer in there. Else, maybe you can continue the thread there. [image] How to evolve complex state (e.g., annotate data)? 🎈 Using Streamlit Streamlit is very convenient to quickly deve…

Thanks for the quick reply. I looked at that question before posting but that is very verbose and a bit diff.

So, I tried a lot based on the suggestions provided in that thread. I tried to use the SessionState as well but it didn’t work. To elaborate again, I am looking to build something like this: Place three buttons Next, Previous, and Reset. The user should be able to reset the state of the button aft…

I don’t think this is possible with streamlit as it currently is, though the current planned for features on their roadmap will make it possible. Specifically the work they are doing on supporting the idea of a state: Right now, getting a Streamlit app to store internal state, like information a u…

Thanks @khalido for the detailed response. I was onto building a much bigger tool than just image annotation but I had to validate the idea using a sample image tagger before combining other functionalities. But yeah, as you said, I think it makes sense to separate out the annotation part from Strea…

Hey all. Just wanted to step in and agree @khalido ’s excellent summary of the situation. Right now, Streamlit is designed for apps that summarize data and/or run inference than it is for apps which require more complex state like annotation. We hear you, though! Data editing apps (and especially …

It is doable with the current streamlit. Here is my simplified app: https://github.com/QuocTran/streamlit_annotate To avoid session state, the trick is keeping a file having the master list of items needed annotation and a file with all the tagged values. At each run, streamlit will show the item t…

Here’s another example of a labeling app that makes use of the SessionState hack: sanzgiri/st_labeler/blob/master/label_videos.py import streamlit as st import numpy as np import SessionState from streamlit.ScriptRunner import RerunException from streamlit.ScriptRequestQueue import RerunDa…

Thanks @Adrien_Treuille for the detailed response. Also, thanks a lot @Quoc_Tran and @areo for the solutions. I will try them and check if they work as desired for my case.
