Error displaying Pyvis HTML inside Jupyter Lab cell
I'm using the Pyvis library to generate and display a network inside Jupyter Lab (in a cell) through the HTML format. I have managed to create the file and open it externally (with the Pyvis save_graph function). However, when using the net.Network(notebook=True) option from Pyvis, Jupyter outputs:
404 : Not Found.
You are requesting a page that does not exist!
While the terminal (from where I launch Jupyter) outputs:
404 GET /files/Documents/(Git)%20Projects/SimSalar/Jupyter%20Notebooks/TRIAL2.html?_xsrf=2%7C9665d25e%7Cbc3fea246105c6b3a9d39f6bbb10d512%7C1607563598&1609770942196 (::1) 1.29ms referer=http://localhost:8888/lab/tree/Documents/(Git)%20Projects/SimSalar/Jupyter%20Notebooks/Workshop%20Analysis.ipynb
The code to get this error, from the Pyvis documentation, is pretty straightforward:
import networkx as nx
from pyvis import network as net
g = net.Network(notebook=True)
nxg = nx.complete_graph(5)
g.from_nx(nxg)
g.show('TRIAL2.html')
Just to clarify, the HTML file is created without any issue (and thus can be opened externally), the problem lies on displaying this file inside JupyterLab (in the cell). I have reinstalled Jupyter multiple times, and used several versions of Jupyter Lab (2.4; 2.6; and 3.0 now). I leave below the full conda environment specifications. I have also given different paths to the g.show('TRIAL2.html') function with the OS module. However, it still does not works.

I saved file using net.save_graph("graphs.html")
Then running following code in cell worked for me
from IPython.display import display, HTML
# Read the contents of the HTML file
with open('<file path >', 'r') as file:
html_content = file.read()
# Display the HTML content
display(HTML(html_content))

Update: Turns out Pyvis (and IFrame) needs the HTML file and the Jupyter Notebook in the same folder for it to be shown correctly (otherwise the notebook throws the 404 error). So, by simply putting the HTML with the notebook in the same working directory, it all went well.
