Error in showing network in pyvis_0.3.2 but not in pyvis_0.3.1

[eivnd]

Hello,

I'm running a simple python code for visualising a network. It works fine with pyvis_0.3.1, but with pyvis_0.3.2 I get the following error message when calling

nt = pyvis.Network('100px', '100px')
nt.from_nx(G)  #networkx graph
nt.show('net.html')

File /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/pyvis/network.py:546, in Network.show(self, name, local, notebook)
    544 print(name)
    545 if notebook:
--> 546     self.write_html(name, open_browser=False,notebook=True)
    547 else:
    548     self.write_html(name, open_browser=True)

    514 check_html(getcwd_name)

    517 if self.cdn_resources == "local":
    518     if not os.path.exists("lib"):

    497                             )
    498 return self.html

I'm seeing the same issue. When running the basic network demo in the README.md, I get the same error:

g = Network()
g.add_node(0)
g.add_node(1)
g.add_edge(0, 1)
g.show("basic.html")

yields:

basic.html
Traceback (most recent call last):
  File "<pyshell#45>", line 1, in <module>
    g.show("basic.html")

    self.html = self.generate_html(notebook=notebook)

Confirmed, same here!

The issue is probably from this commit https://github.com/WestHealth/pyvis/commit/4c5af7adb840fb6f8b7296c74fab6ecfc7c34e1f#diff-405e696560a2f03a44724592eb5a5cc65a972a257e639619c0a8f88a0069c0b9R536 , where the notebook kwarg was introduced and set to True by default. Calling show with notebook=False fixes the issue indeed. To avoid breaking backwards compatibility, notebook should be set to False in the function definition. Note that inline docs have also been neglected in that commit, the new param is not in the docstring. @BerserkerGaruk
