Unable to produce county choropleth with plotly 4.1 and chart_studio

📊 Plotly Python
1

Since upgrading to plotly 4 and attempting to use the chart_studio functionality, I have been encountering some very strange behavior when trying to make a county choropleth map. I can get the map to work when I install plotly without chart_studio, but not when I install it with chart_studio. The following code does not work:

In Anaconda prompt (as far as I can tell, I am following the instructions from the getting started page exactly):

conda create -n choropleth-test python=3.7
conda activate choropleth-test
conda install -c plotly plotly=4.1.0
conda install "notebook>=5.3" "ipywidgets>=7.2"
conda install -c plotly plotly-geo=1.0.0
conda install -c plotly chart-studio=1.0.0
conda install geopandas

In jupyter notebook (this is the example from the county choropleth page):

import chart_studio.plotly as py
import plotly.figure_factory as ff

fips = ['06021', '06023', '06027',
        '06029', '06033', '06059',
        '06047', '06049', '06051',
        '06055', '06061']
values = range(len(fips))

fig = ff.create_choropleth(fips=fips, values=values)
fig.layout.template = None
py.plot(fig,filename = 'choropleth-test', auto_open=True)

I then get the following error message:

---------------------------------------------------------------------------

ImportError: geopandas, pyshp and shapely must be installed for this figure factory.

Run the following commands to install the correct versions of the following modules:

$ pip install geopandas==0.3.0
$ pip install pyshp==1.2.10
$ pip install shapely==1.6.3

If you are using Windows, follow this post to properly install geopandas and dependencies:http://geoffboeing.com/2014/09/using-geopandas-windows/

If you are using Anaconda, do not use PIP to install the packages above. Instead use conda to install them:


$ conda install plotly
$ conda install geopandas

However, the following code does work (not using chart_studio here):

In Anaconda Prompt:

conda create -n choropleth-test-plotly2 python=3.7
conda install plotly
conda install geopandas

In Jupyter Notebook:

import plotly as py
import plotly.figure_factory as ff

fips = ['06021', '06023', '06027',
        '06029', '06033', '06059',
        '06047', '06049', '06051',
        '06055', '06061']
values = range(len(fips))

fig = ff.create_choropleth(fips=fips, values=values)
fig.layout.template = None
fig.show()
