Does Plotly 4.2.0 depend on scikit-image?

[qutang]

I failed to import plotly.figure_factory because plotly seems not to install scikit-image when running pip install -U plotly. After I manually installed scikit-image, import plotly.figure_factory worked.

This was not a problem in version 4.1.1.

But the source code shows it depends on it.

plotly.py/packages/python/plotly/plotly/figure_factory/_ternary_contour.py

Line 11 in b7ad543

from skimage import measure

One of our figure factories depends on scikit-image, yes, but not the library as a whole.

So the answer is that in 4.2 we accidentally made all figure factories depend on scikit-image, rather than just the one that needs it, and we'll fix that.

Fixed in 4.2.1
