conversion fails with scatter3d

[YurongYou]

Hi,

I found I can save the 2d scene to image but could not do it on 3d, could you help me on this? i.e.

it works fine on

pio.write_image(go.Figure(data=[go.Scatter(
        x=[1],
        y=[1],)]),'simple_fig.png')

but on

pio.write_image(go.Figure(data=[go.Scatter3d(
        x=[1],
        y=[1],
        z=[1])]),'simple_fig.png')

I got

---------------------------------------------------------------------------
