Issue with widgetbox in Bokeh

[GhsJahanmir]

Hi,
This repository is very useful. However, after installation of cimcb, when I tried to import it, I got the following error.
I appreciate any suggestion to tackle with it.

Traceback (most recent call last):
File "", line 1, in
File "C:\Users\user\AppData\Roaming\Python\Python311\site-packages\cimcb_init_.py", line 3, in
from . import bootstrap
File "C:\Users\user\AppData\Roaming\Python\Python311\site-packages\cimcb\bootstrap_init_.py", line 2, in

from bokeh.layouts import widgetbox, gridplot, column, row, layout
ImportError: cannot import name 'widgetbox' from 'bokeh.layouts' (C:\ProgramData\anaconda3\Lib\site-packages\bokeh\layouts.py)

Best,
