RuntimeError: can't register atexit after shutdown

[aswinnarayanan]

I followed the advanced installation on miniconda

git clone https://github.com/yjmantilla/sovabids.git
cd sovabids
pip install -r requirements-dev.txt

python -c 'from sovabids.datasets import lemon_prepare; lemon_prepare()'

python front/app/app.py gives the following error

* Serving Flask app 'app' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.

For me the new version works fine, but notice that I did the "pip install -r requirements-dev.txt" already for an older version of SOVABIDS, so no python packages had to be installed.

@aswinnarayanan what OS do you use?

[aswinnarayanan]

I tried it on Windows and WSL-ubuntu 20.04

[yjmantilla]

Im almost sure it must be this https://stackoverflow.com/questions/65467329/server-in-a-thread-python3-9-0aiohttp-runtimeerror-cant-register-atexit-a ,

it is missing a thread.join after the start

[yjmantilla]

This probably hints I should do a CI test for the GUI, Im sure that maybe with selenium I could infact simulate the procedure. It may be quite cumbersome with GUI changes.

[yjmantilla]

The fix I applied in v0.1a1+26.gc6dde77.dirty (or just the latest version) should fix this

[aswinnarayanan]

That's fixed it
