Write Image as PDF with Box saying "Loading [MathJax]/extensions/MathMenu.js"

Hello,

library(plotly)

n <- 1e3
x <- rnorm(n)
y <- 2*x + rnorm(n, sd = 5)

fig <- plot_ly(x = x, y = y, alpha  = 0.01,type = "scatter")

save_image(fig,"test.pdf")
browseURL("test.pdf")

When I run the above code, I get the box saying Loading [MathJax]/extensions/MathMenu.js，I see the Solution in plotly.py issues 3469:

import plotly.io as pio   
pio.kaleido.scope.mathjax = None

How should I solve it in R？

Commencez par reproduire l’exemple save_image(fig, "test.pdf") avec plotly 4.10.0 sur la configuration Ubuntu signalée, puis comparez le chemin d’exportation R avec l’issue 3469 de plotly.py. Examinez comment webshot2 et chromote gèrent la page de chargement de MathJax. Le travail est considéré comme terminé lorsque l’exportation PDF s’achève sans la boîte de chargement et que le comportement est couvert par une vérification de régression appropriée.
