hi dears

https://paste.ubuntu.com/p/TW8DHc7CTm/

and then not found page save

can you anybody help me please???

Hi @gfdfgdg,

This is the forum for the plotly python library, which doesnโ€™t interact with the tornado framework. Youโ€™ll probably have better luck looking for help on stack overflow or on some tornado-specific forum.

Good luck!
