You have run into a bug. Looking at the _types.py file, one can see your layer falls through the cracks of conditional statements in the add_layer method. If you just want the error message to go away, insert the following in between Lines 06 and 07 of your original code:

df_layer<SPAN class="punctuation token">.</SPAN>layer<SPAN class="punctuation token">.</SPAN>layers <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN>dict<SPAN class="punctuation token">(</SPAN>df_layer<SPAN class="punctuation token">.</SPAN>layer<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

As as soon Esri fixes the bug, you will want to remove this line because it may either generate an error or overwrite valid information created upstream.

Thanks for reporting, this bug should be fixed in the next release of the API.

Honestly, I am not even sure that using "x" and "y" columns the way you have is supposed to work, such a workflow surely isn't documented:

https://community.esri.com/thread/207926-importdata-documentation-or-code-bug

JasonCarter

Thank you for your help. This brings up another question, is the X,Y data being displayed only locally or does the GIS() object temporarily host the layer in ArcGIS online? I did not sign into GIS().

Thank you.

Hi,

Thank you -- I made a lot of errors retyping my code.

I was able to add the data to the map (see image) after fixing my previous errors and renaming the lat/long fields to y,x.

I am still recieving the following error even though the data points are on the map:

After sorting out loading data from the CSV file, the next issue you will run into is Line 06. Although Line 06 will work, I don't think it returns the object you are expecting/wanting. The import_data - arcgis.gis module — arcgis 1.3.0 documentation states:

Imports a Pandas data frame (that has an address column), or an arcgis spatial dataframe into the GIS.

You don't have any address columns, you have longitude and latitude columns. The object returned from import_data() will simply be a table, not a spatial layer. I don't know if that is causing the error, but it is helpful to include the whole Traceback when posting errors:

How are you getting Line 05 to work? The core Pandas module has no method from_csv(), that is in the DataFrame object. There is a read_csv() you can use.

JasonCarter

Oh, well I forgot to include

import pandas as pd

In my code sample. I'm using version 3.6.2

version? I can't get past line 4 without your code throwing an error
