arcpy.mp.LayerFile() OSError

Question

I'm new to GIS programming, and am going through the Esri "Getting Started with arcpy.mp" tutorial.

When I try the following:

lyrFile = arcpy.mp.LayerFile(r"path to a layer file")

I get the following error:

File "", line 1, in File "c:\users\ME\appdata\local\programs\arcgis\pro\Resources\arcpy\arcpy_mp.py", line 773, in init self._arc_object = arcgisscripting._mapping.LayerFile(*gp_fixargs((layer_file_path,), True)) OSError: C:\Users\ME\Documents\ArcGIS\myLayer.lyrx

Typical google search doesn't really bring up much except for Adding feature class to Map in CURRENT project using ArcPy in ArcGIS Pro?

I've tried the alternate methods of adding a Layer file as suggested in the question thread, but get the same OS error.

What is causing this error, so I can figure out how to resolve it?

Are you using ArcGIS Desktop or ArcGIS Pro? lyrx is a ArcGIS Pro layer file — BERA, Oct 24 '18 at 13:29
Yep, just discovered my error! Doing tutorial in Pro, trying to use layer created in Desktop 10.5 which has a '.lyr' extension, not '.lyrx' — luser3228561, Oct 24 '18 at 13:38
I save as the .lyrx layer in ArcPro but still get the same error. — user131242, Nov 5 '18 at 13:37

I needed to pay attention to file extensions!

The tutorial assumes you created the layer file in ArcGIS Pro. I was attempting to add a layer created in ArcGIS Desktop 10.5, which has the '.lyr' extension, NOT '.lyrx'.
