Warning for axis_metric

See original GitHub issue

Let’s set up a small embeddingset.

from whatlies.language import SpacyLanguage
from whatlies.transformers import Pca

words = ["prince", "princess", "nurse", "doctor", "banker", "man", "woman",
         "cousin", "neice", "king", "queen", "dude", "guy", "gal", "fire",
         "dog", "cat", "mouse", "red", "bluee", "green", "yellow", "water",
         "person", "family", "brother", "sister"]

lang = SpacyLanguage("en_core_web_md")
emb = lang[words]

Let’s now make some charts.

emb.transform(Pca(2)).plot(kind='scatter', annot=True)
emb.transform(Pca(2)).plot(kind='scatter', annot=True, axis_metric='cosine')
emb.transform(Pca(2)).plot(kind='scatter', annot=True, axis_metric='euclidean')

At the moment, they all seem to return this chart.

It took me a while to realise that the reason why this was not working as expected was because of the fact that I’m not using "king" as an x_axis/y_axis. Maybe we should introduce a warning here. Might be more user friendly.

It’s certainly in the docs, and this was certainly a moment of “lack of attention” on my part, but I can imagine that these small changes can help beginning users. I’ll add a small warning.

Well, I have mentioned this in the docstrings that custom metric is only effective when the axis is a string or an Embedding (hence it will be ignored when integer axis is provided, which is the default):

https://github.com/RasaHQ/whatlies/blob/6811b7a24b71f169c5b97a0f8a17572f07f96f94/whatlies/embeddingset.py#L949-L950

But we can also add a warning for it if you consider it to be useful.
