Couldn't load plugin 'network_gt' due to an error when calling its classFactory() method

[Saijin-Naib]

It looks like chart-studio must be used instead of the plotly chart functions. I am unable to load/use NetworkGT due to this error.

ImportError: The plotly.plotly module is deprecated, please install the chart-studio package and use the chart_studio.plotly module instead.

Hi Saijin-Naib,

What version of plotly are you using? NetworkGT uses the QGIS version of plotly - version 3.3. In the future i foresee that QGIS will update to version 4 but at the moment this will cause a lot of compatibility issues.

Bjorn,

I am using plotly 4.4.1 from PIP. I see that I have caused this problem.

Thanks for the heads up!
