Binder yfinance

[robertmartin8]

yfinance is not available in the binder notebooks. I added it to the pyproject.toml as a dev dependency, and also added pip install in the Dockerfile, but I keep getting ModuleNotFoundError.

It seems that binder is only looking at requirements.txt when it sets up the environment, so I may have to add yfinance to the requirements (either that or make all of the notebooks read from local data).

@phschiele any thoughts?

First of all, it is correct that binder only looks at the requirements.txt file. Sadly, one cannot set different priorities such that it would read from a more robust format.

So I see three solutions:

• add it to requirements.txt
• rewrite all notebooks to use local data -> I think loading the prices directly from yfinance makes the notebook always feel "up to date", which I like
• some hack like ! pip install yfinance in the notebooks

Personally, I would go for the first one. I guess for the time being, requirements.txt will always be a subset of main, dev, and optional dependencies, which is fine for this "fallback" file.
