RuntimeError error when loading local data to the map widget.

Hello,

In Arcpro Jupyter Notebook, I am trying to get a map widget with data from our local system/network. My code is:

from arcgis.gis import GIS gis = GIS("pro") from arcgis.widgets import MapView MapView.set_js_cdn("https://js.arcgis.com/4.18/") map1 = gis.map("macon, GA") map1.basemap = "topo" map1.add_layer("N:\name\shp\shapefile.shp") map1

I am getting the following error:

RuntimeError Traceback (most recent call last) In [14]: Line 8: map1.add_layer("N:\name\shp\shapefile.shp") File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\widgets\_mapview\_mapview.py, in add_layer: Line 1153: self._add_layer_to_widget(item, options) File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\widgets\_mapview\_mapview.py, in _add_layer_to_widget: Line 1263: raise RuntimeError("Cannot infer layer: will not be added to map") RuntimeError: Cannot infer layer: will not be added to map

What does this error mean, and how do I fix it? Also, where is some good documentation on errors that occurs in Jupyter Notebooks?

Again I am just trying to gain familiarity with Jupyter in Arcpro. The ability to use our data in a Jupyter Notebook will be essential to any applications of the feature.

Arc Pro: 2.7

Thank you,

Laura

You are trying to add a layer that ArcGIS for Python API doesn't understand. The documentation for add_layer requires

Layer objects such as FeatureLayer, MapImageLayer, ImageryLayer etc.

Item objects and FeatureSet and FeatureCollections

Table objects

which are referring to web based/ hosted types of data... I know you can access local featureclasses/ data for analysis and the like, but I don't think it extends to webmap widgets. You could host that shapefile in AGOL and access it that way.

Thanks for the Explanation. Do you know where I can find documentation on the errors.

Sorry for the delay- I don't think ESRI keeps a repo of all the errors, at least any that are publicly accessible. This thread might provide you some answers on what error codes are there, how to get a list of them and since they keep the codes consistent across the platform (maybe?), you can probably search for the code and get the documentation for it.
