dash-renderer issue when loading python dash

[wsebastiangroves]

After initializing my dash code in python and receiving no errors, I open Chrome to my local Dash page and it's blank white with the following error:

(This error originated from the built-in JavaScript code that runs Dash apps. Click to see the full stack trace or open your browser's console.)
Error: dash_table_experiments was not found.

My library list:
import pandas as pd
import dash_core_components as dcc
import dash_html_components as html
import dash_table_experiments as dt
import dash.dependencies
from dash.dependencies import Input, Output, State
import plotly

dash_table_experiments loads in python just fine, but doesn't seem to outside of that.

The full stack trace seems to include only references to dash_renderer, so that's why my question is: What is happening to dash_renderer/dash_table_experiments, and how can I fix it?

Before we dig into debugging (for which we'd want to see versions of all these packages plus python itself, and a complete runnable code example), I should point out that dash_table_experiments has been deprecated and hasn't been updated for a year now, in favor of dash_table. The last major feature we're aware of that experiments did better is filtering. Updated filtering capabilities will be part of the next dash_table release, due out next week. Other than that, is there anything dash_table_experiments does for you that dash_table doesn't match?

I read your comment when you posted and worked on it over the weekend. I managed to replace dash_table_experiments with dash_table, rework my script as needed, and, voilà, I have my first dash up and running. Thank you for letting me know that dash_table_experiments is deprecated and that dash_table is the current favorite.

For any future reference, this is the link to the guide I followed that helped me get started with dash_table:

dash_table_experiment enables having components other than plain text in each cell. This is something dash_table does not support. I ran into the same issue 'dash_table_experiment not found' when I was trying to use it for adding hyperlinks in table cells.

why is it referring to dash_renderer.dev.js instead of dash_renderer.min.js

[alexcjohnson]

@Chiragasourabh this repo is obsolete, dash-renderer is part of the main dash repo now. Anyway, you get the dev bundle when you run the app in debug mode, as it includes extra devtools.
