Unable to render outside of a notebook context

[cpsievert]

The suggested way of getting standalone HTML from ipywidgets doesn't appear to work:

import pandas as pd
import numpy as np
import json

from ipydatagrid import DataGrid, TextRenderer, Expr

n = 50_000

df = pd.DataFrame(
    {
        "Value 1": np.random.randn(n),
        "Value 2": np.random.randn(n),
        "Value 3": np.random.choice([True, False], n),
        "Value 4": np.random.choice([True, False], n),
    }
)

def bool_render_text1(cell):
    if cell.value > 0:
        return "\uf00c"  # Check
    else:
        return "\uf00d"  # Cross

def bool_render_text2(cell):
    if cell.value > 0:
        return "\uf111"  # Circle
    else:
        return " "

def bool_render_text3(cell):
    if cell.value:
        return "\uf164"  # Thumb up
    else:
        return "\uf165"  # Thumb down

def bool_render_text4(cell):
    if cell.value:
        return "\uf118"  # Smile
    else:
        return "\uf119"  # Frown

def bool_render_color(cell):
    if cell.value > 0:
        return "#2fbd34"
    else:
        return "#b82538"

common_args = {
    "font": "bold 14px fontawesome",
    "text_color": Expr(bool_render_color),
    "horizontal_alignment": "center",
}

renderers = {
    "Value 1": TextRenderer(text_value=Expr(bool_render_text1), **common_args),
    "Value 2": TextRenderer(text_value=Expr(bool_render_text2), **common_args),
    "Value 3": TextRenderer(text_value=Expr(bool_render_text3), **common_args),
    "Value 4": TextRenderer(text_value=Expr(bool_render_text4), **common_args),
}

#display(df)

w = DataGrid(df, base_row_size=30, base_column_size=150, renderers=renderers)

from ipywidgets.embed import embed_minimal_html

embed_minimal_html("index.html", w)

$ python3 -m http.server

Hello 👋 @cpsievert and welcome to the ipydatagrid community!

Looking at your error above, it seems like you have an issue with the ipytree package. Can you check again and let me know?

Thanks!

Whoops, I included the wrong screenshot, I just updated it to the correct one :)

@cpsievert I am going to take a look at this in the first week of January. Happy new year! 😄

Since ipytree was mentioned I allow myself to ask if ipytree is also a blommberg based create package? Thanks
