Editor.py missing package jpy_canvas

Hello eveyone!
The 6th line of python file which is located in flatland/flatland/utils/editor.py cannot be executed properly.
The code “import jpy_canvas” points at the missing github repository “https://github.com/who8mylunch/Jupyter_Canvas_Widget.git”, so i couldn’t install this package.

The main reason why I want to use this module is that i want to build a real train network in my reasearch. And I have seen this discussion “How can I create a rail network, which is just a simple circle?”, suggest me running this notebook file “https://gitlab.aicrowd.com/flatland/flatland/-/blob/master/notebooks/Scene_Editor.ipynb”, but this file will import editor.py which import the missing package jpy_canvas.
How can I fix this bug? Thank you!
