Not working in windows cmd prompt

from lets_plot import *

Hello, @alshan Thanks for you reply. Importing issue solved. I tried

> from IPython.display import display, HTML
> display(HTML("<h1>Hello!</h1>"))

in Rstudio, I didn’t render the Hello! as other Python IDE did. So I guess Rstudio can’t make it come true at the moment.

Hi @antonio-yu , when in R/Reticulate try to activate your conda environment (where m2w64-toolchain and lets-plot were inatalled to) using the use_condaenv() function. See details here: https://rpubs.com/dku850/603511

I hope this will resolve the lets-plot importing issue in RStudio.

As for rendering, lets-plot relies on IPython API. Make sure it is installed in your python environment as well. Check whether it works in RStudio :

from IPython.display import display, HTML

display(HTML("<h1>Hello!</h1>"))

If this code works than lets-plot will likely be able to display plots in RStudio. If not than this is unlikely.
