Folium throwing a bunch of errors

[LaurentBerder]

Hi,

I'm just trying out PyMove because it seems like it could bring a lot to my current project.
But I can't get any folium functionality to work, though.

Here's an extract of what I'm doing:

df.head()

absolute_time	lat	lng	id
2021-09-09 10:32:27.000	45.818459	3.139887	54
2021-09-09 10:32:28.000	45.818459	3.139887	54
2021-09-09 10:32:29.044	45.818459	3.139887	54
2021-09-09 10:32:30.000	45.818459	3.139887	54
2021-09-09 10:32:31.000	45.818459	3.139887	54

move_df = MoveDataFrame(data=df, latitude='lat', longitude='lng', datetime='absolute_time')

from pymove import folium as f
f.plot_trajectories(move_df)

Or if I just try to plot the bounding box, I get a different error.

I'm using python version 3.7, PyMove version 3.0.0, and folium version 0.8.3

Hi. For some methods, PyMove requires folium version >=0.10.1. It is pinned in the requirements, so it should update when installing PyMove. If not, try using:

pip install -U folium'>=0.10.1'

If you are using it on Google Colab, I believe it has the version 0.8.3. After installing PyMove or updating folium, restarting the environment should do it.

Sorry for the delayed response.
