Error while running the demo-'Explore the world' in Colab

[dkbs12]

Hello,
When I ran the demo 'Explore the world' in Colab, I failed to start up the app on localhost:8501.
So I'd like to ask you to look over the below codes and help me solve this problem.
This is my codes for Colab;

cd "/content/drive/MyDrive/CheckNDC project/UI/streamlit/haystack-search-pipeline-streamlit"
!git clone https://github.com/deepset-ai/haystack-search-pipeline-streamlit.git
cd "/content/drive/MyDrive/CheckNDC project/UI/streamlit/haystack-search-pipeline-streamlit test/haystack-search-pipeline-streamlit"
!pip install -r requirements.txt
!streamlit run app.py

Finally, I got the response as below;

Collecting usage statistics. To deactivate, set browser.gatherUsageStats to False.
You can now view your Streamlit app in your browser.
Network URL: http://172.28.0.12:8501/
External URL: http://34.86.134.61:8501/

I've tried both of the URL above, but I found the error message told me 'cannot connect to the site'.
I can't use docker to implement 'Explore the world', because I need to keep using Colab for using its GPU.
So I cloned the github repository into my google drive and ran the app.py file in Colab.
Please help me with this matter.
Thanks.

Hello @dkbs12 I wouldn't recommend trying to run this demo in google colab. Google colab is just not built for this purpose and you will have a hard time trying to expose the port and access the site, though you might find people discussing this idea in the streamlit discussion forum here. Instead, please have a look a the instructions on running the demo in HuggingFace Spaces.
