@yashwatwani This looks like a Bokeh versioning problem if you are able to import from lib.call_backs import input_callback, selected_code successfully. What version of Bokeh do you have?

Check the version of Bokeh:

import bokeh
print(bokeh.__version__)
1.3.4

Could you please install the version 1.3.4 and try again.
If using conda:
conda install bokeh=1.3.4

If using pip:
pip install 'bokeh=1.3.4'

Please let us know if this fixes the problem.

Edit: Correction on the Bokeh version (not 2.0.1, but 1.3.4)

[MaksimEkin]

We were able to reproduce the error by upgrading to Bokeh 2.0.1. Using Bokeh 1.3.4 resolves the error; therefore, closing the issue.

Hi,

I am new to this forum and python programming..

I was trying to run the code in my system, below is the error I get when I run - "from call_backs import input_callback, selected_code"

How do I install call_backs in conda.

ModuleNotFoundError Traceback (most recent call last)
in
----> 1 from call_backs import input_callback, selected_code

ModuleNotFoundError: No module named 'call_backs'

[MaksimEkin]

Make sure the lib folder is in the same directory as the Notebook. Error is complaining about call_backs.py.

[Shruthihanu]

Hi,

Yes, error is on call_backs.... not sure how to install this module.

can you guide me.

[SoloNick]

“call_backs” is in lib/call_backs.py. You cannot conda install it.
