Covid Network Container Visual

I installed and launched MelodieStudio. Then I ran run_simulator from the CovidNetworkContagionVisual tutorial. The web page did not connect. Here is the output from the front-end and back-end, respectively:

 * Serving Flask app 'MelodieStudio.main'

Hi @rusu24edward , we have pushed a new version of MelodieStudio onto pypi, please re-install the MelodieStudio package, restart this demo, and try to visit http://127.0.0.1:8089 by browser. Thanks!

I've reinstalled my virtual environment from scratch using Python3.8 and installed MelodieStudio version 0.6.0. If I'm in the Melodie repo root, I can call python3 -m MelodieStudio and it returns

python3 -m MelodieStudio
 * Serving Flask app 'MelodieStudio.main'

 * Running on http://127.0.0.1:8089
 * Running on http://128.15.167.49:8089
Press CTRL+C to quit

When I open http://127.0.0.1:8089, I just see a blank page. I think this is expected since this is the Melodie repo and not a tutorial, but please correct me if I'm wrong.

I hop over to CovidGridContagionVisual and run python3 -m MelodieStudio, and I receive the following error:

python3 -m MelodieStudio

Same error when I try CovidNetworkContagionVisual.

@rusu24edward Sorry, I forgot to push the updates to the CovidNetworkContagionVisual repository. Could you please re-pull this repo and retry? Thanks!

When I attempt to use python3 -m MelodieStudio in CovidGridContagionVisual, the browser is just blank, and nothing seems to happen when I run run_simulator.py. Here's the output:

The same thing happens in the CovidNetworkContagionVisual.

Are you testing this yourself after you push a change? I'm just curious how it is working for you but not for me.

Hi @rusu24edward, this is weird... but the computer is never wrong... @hzyrc6011 tested again today and told me it was fine on his laptop. He is exploring some other reasons and will come back to you.

@SongminYu - How about testing the software in a newly installed virtual machine?

Hi @jbytecode, thanks! Yes, @hzyrc6011 also tried with docker. He is more experienced than me so he is trying to solve the issue. We have some time lag. He is in China and I am in Europe. So he is sleeping now. I think he will try again tomorrow. We will try to solve this soon.

@jbytecode Thanks for your suggestion, and today I tried it on a ubuntu-22.04 server. The commands that I used for installing dependencies were:

# at the folder of /home/ubuntu

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.8-* -y # installed the pre-built python package, and the building dependencies for python wheel c extensions

# clone Melodie to build the wheel
git clone https://github.com/ABM4ALL/Melodie.git

cd Melodie/
python3.8  -m pip install -r build_requirements.txt 
python3.8 setup.py bdist_wheel
python3.8 -m pip install dist/Melodie-0.6.0-cp38-cp38-linux_x86_64.whl 

# install MelodieStudio
python3.8 -m pip install MelodieStudio

And after starting the simulator and studio, I visited http://<address_of_server>:8089, then the page was showed in the browser as the following picture:

If the problem still happens even after refreshing the visualization page, and the browser showed a completely blank page(even without any error code), could you please provide a screenshot inside the browser developer tool (Could be accessed by F12)? The screen shot for Console tab and Network tab will be helpful.

Console page

Network page

Sorry again for this problem, we will struggle to find out how to fix it.

@rusu24edward Thanks for the comment with problems, I found this was due to a misconfiguration of CDN in MelodieStudio, and we tried to fixed this problem. Also, the fixes have already been tested on Windows, MacOS and Linux.

For Melodie, please install the latest commit on master branch; For MelodieStudio, please install this wheel: https://github.com/ABM4ALL/MelodieStudio/releases/tag/0.7.0.dev1

After starting the Visualizer and MelodieStudio, the MelodieStudio will show the following message. Note that if melodieStudio started before the visualizer, it may raise ConnectionRefusedError because it cannot connect to the visualizer.

Following this message, please visit http://localhost:8089 page to see if this bug was fixed. Thank you again for your patience in helping us to deal with this problem!

I followed these instructions, and I was able to get the Network Visual tutorial to work. Thanks for your hard work to fix this! Very cool visualization, definitely worth the effort.

I did try the Covid Grid Visual tutorial, and I got the following error:

python3 -m MelodieStudio

@rusu24edward Thanks a lot! We will have a look at this issue. We also noticed that there are still some aspects of MelodieStudio that need improvements. We will also try to fix them and release a new version!

Hi @rusu24edward, we just released a new version 0.7.0 of Melodie and MelodieStudio. Now both examples of Network and Grid can be visualized! Thanks a lot!
