In Pyvis I get UnicodeEncodeError: 'charmap' codec can't encode characters in position 263607-263621: character maps to

Question

In pyvis, Why I get this error when I am trying to visualise a simple graph (3 lines of codes only)?

net=Network(notebook=True, cdn_resources='in_line')
net.from_nx(nx.davis_southern_women_graph())
net.show('example.html')

This leads to the error:

Traceback (most recent call last):
  File "g:\My Drive\....\graph_v.py", line 270, in <module>
    net.show('example.html')

    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode characters in position 263607-263621: character maps to <undefined>

Some research yielded that I need to update the encoding to UTF-8 but when calling which method and how?

Answer 1

One possibility could be

from pyvis.network import Network
import networkx as nx
from IPython.display import display, HTML

net=Network(notebook=True, cdn_resources='in_line')
net.from_nx(nx.davis_southern_women_graph())
# net.show('example.html')

html = net.generate_html()
with open("example.html", mode='w', encoding='utf-8') as fp:
        fp.write(html)
display(HTML(html))

that generates the image below. It is not necessary to store the html file, but you may wish to do so.
