TemplateNotFound in conda environment

[Sieboldianus]

I am trying to run the example Jupyter Notebook in ../master/examples/notebooks/scale-annotation.ipynb

I've set up my environment with conda: conda install -c conda-forge mapboxgl

The file paths I've tested:

1. relative path

--mapboxgl-jupyter
----scale-annotation.ipynb
----data
------healthcare_points.geojson
----templates
------circle.html

2. up directory path

--mapboxgl-jupyter
----scale-annotation.ipynb
--data
----healthcare_points.geojson
--templates
----circle.html

3. local

--mapboxgl-jupyter
----scale-annotation.ipynb
----healthcare_points.geojson
----circle.html

All of these give me:

    111         # first we try to get the source for this template together
    112         # with the filename and the uptodate function.

    234         if not self.provider.has_resource(p):

@Sieboldianus just out of curiosity: are you able to execute any of the notebooks in your conda installation?

[Sieboldianus]

Yes, I've just tested with cloning the entire Github Repo and walking through the example notebooks folder. I get errors for all of these, e.g.:

linestring-viz.ipynb

Do I have to do anything to set the template resource folder?

[akacarlyann]

Ah I see. I'm not sure if the conda distribution task was finished in #65, since that issue is still open. @ryanbaumann do you have more info?

[pybanaszak]

I have the same issue on my side using Anaconda 2019.07. I already used your package without any issue.

To solve this issue I had to add the templates folder of your repo in this repo on my mac : ~/anaconda3/lib/python3.7/site-packages/mapboxgl/ now the map is showing inside the iframe, but no data/markers are showing up.

My code :

from mapboxgl.utils import *
from mapboxgl.viz import *

# Generate color stops from colorBrewer
measure_color = 'Appearances'
color_breaks = [round(appearances_per_city[measure_color].quantile(q=x*0.1), 2) for x in range(2, 10)]
color_stops = create_color_stops(color_breaks, colors='Blues')

# Generate radius breaks from data domain and circle-radius range
measure_radius = 'Appearances'
radius_breaks = [round(appearances_per_city[measure_radius].quantile(q=x*0.1) , 2) for x in range(2,10)]
radius_stops = create_radius_stops(radius_breaks, 0.5, 9)

# Create the viz
viz = GraduatedCircleViz('appearances.geojson',
                         access_token=token,
                         height='320px',
                         color_property='Appearances',
                         color_stops=color_stops,
                         radius_property='Appearances',
                         stroke_color='black',
                         stroke_width=0.5,
                         radius_stops=radius_stops,
                         center = (20, 50),
                         zoom=3,
                         below_layer='waterway-label')

viz.show()

Here is the error message I get without the template folder :

@akacarlyann correct, I did not publish the Anaconda distribution currently in Conda Forge. That's why the issue in this repo (https://github.com/mapbox/mapboxgl-jupyter/issues/65) is still open.

[raerickson]

@ryanbaumann as an FYI, this issue is still haunting Conda Forge over a year later. For anybody looking for the quick fix in the terminal, here it is:

pip uninstall mapboxgl
pip install mapboxgl

[kinow]

There are two archives in PYPI, one the source distribution, and the other a wheel file. The wheel contains the templates folder, but the source distribution doesn't.

The conda package is built using the PYPI source distribution, so the Conda Forge installation results in a module without the templates folder.

I downloaded the wheel file, unzipped it, then copied the templates folder over to my conda env directory ~/Development/python/miniconda3/envs/csl-load-count-ml/lib/python3.8/site-packages/mapboxgl. Now my notebook is running OK.
