Colaboratory Notebook that hosts a streamlit app and creates an ngrok https tunnel for access.

streamlit_colab.ipynb

btw I have some colab here. u can see it. Can I use Streamlit on them? Ty mf.

I took a quick look. I think you can make prototypes and develop with Streamlit on Colaboratory, but you wouldn't want to make that your production server as Colaboratory has a relatively short timeout (only about 12 hours). You can find more on how Streamlit could maybe fit with your projects here: https://www.streamlit.io/

Thank you so much for this brilliant piece of code.....👌👌

this is awesome thanks a lot

when I clicked on the URL it is showing me

"Tunnel f9b2788c5740.ngrok.io not found"

Hey m getting this error. could you help?
get_ipython().system_raw('./ngrok http 8501 &')

Thanks but this problem is solved. it was ngrok version issue

Legend..thanks for demystifying it on colab. Had totally hit a wall on my own..

Thanks guys! It can work in colab!
But i see some difference between run in colab and run in local.
When i run streamlit hello in local, I choose Animation Demo and run it. The Animation move move and move ...
But i run streamlit hello in colab like your code, I choose Animation Demo however the Animation don't move. only stand still
Why?

Thank you very much for this

Hey! I am getting this error when I try opening "https://2f10-35-196-239-11.ngrok.io/" this link. Please help.

The connection to https://2f10-35-196-239-11.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:80.

Make sure that a web service is running on localhost:80 and that it is a valid address.

The error encountered was: dial tcp 127.0.0.1:80: connect: connection refused

I have the same problem as you. Did you solve it?@Aishwary-Rawal
I use VPN when I am using Colab. Is the problem related to this?

Hi,
I get the following error.

I could not use this way. the localhost refused. thus, i find the other way to solve it
npx create localtunnel and show the url to check in the browse

!streamlit run app.py & npx localtunnel --p 8501

Hi, I get the following error.

try this one. only on line code

!streamlit run app.py & npx localtunnel --p 8501

https://youtu.be/zdJdJ1tHGnA , you can watch video for running streamlit in local hoast using localtunnel
