Cannot import 'Layer' from arcgis.mapping

Sfortunatamente — Tue, 04 Jul 2023 13:03:54 GMT

Hi,

I am working on a simple script which copies a web map and adds a new layer:

from arcgis.gis import GIS
from arcgis.mapping import WebMap
from arcgis.mapping import Layer

I receive:

ImportError: cannot import name 'Layer' from 'arcgis.mapping' (C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\mapping\__init__.py)

ArcGIS Pro 3.1.1

What is wrong?

Thanks.
-b.

There is no class Layer in arcgis.mapping .

Here are some classes that could be what you want:

for x in arcgis.mapping.__dict__.keys(): print(x)

...
MapImageLayer
MapImageLayerManager
...
VectorTileLayer
...
Object3DLayer
IntegratedMeshLayer
Point3DLayer
VoxelLayer
PointCloudLayer
BuildingLayer
SceneLayer
...
MapServiceLayer
MapFeatureLayer
MapTable
MapRasterLayer
...

It's also possible that you actually want arcpy.mp.Layer ...

What do you mean AI? It's the ArcGIS documentation that shows code snippets that error.

`ImportError: cannot import name 'WebMap' from 'arcgis.mapping'`

from arcgis.mapping import WebMap, WebScene
