Display all hoverinfo of Nodes when plotting network data - python

Dear,
I am working on plotting the network graph data on plotly as following link: https://plot.ly/python/v3/network-graphs/

However, I am looking for a solution that could trigger the event that we display all the nodes hoverinfo, which quite similar to this one https://plot.ly/javascript/hover-events/#triggering-hover-events but actually display all the hoverinfo, not in a random way. Then we could turn it off.

Thanks in advance
