Widgets for folium heatmapwithtime plugin not showing up.

[pfwangs]

Please add a code sample or a nbviewer link, copy-pastable if possible

I am trying to follow this guide, however, I get the same made twice even when I use https://nbviewer.jupyter.org/github/python-visualization/folium/blob/master/examples/HeatMapWithTime.ipynb

# hm = plugins.HeatMapWithTime(
    data,
    index=time_index,
    auto_play=True,
    max_opacity=0.3
)

Output of folium.__version__

is this issue resloved?

We would need more information to investigate this. At least a code snippet that produces the error, any relevant error messages in Python or in your browser console, screenshots of how the map looks like, etc.

this code for instace is not showing the heatmapwithtime

Hello,

I have run your code, and I do get two different heat maps, the first one does not have any timestamps (made by your first bit of code up to just before you import from datetime) and the second one (using the code from the datetime import onwards) does contain timestamps.

Here is a screenshot of the second heatmap:

I made this with the latest version of folium from the master branch.

Mark.
