arcpy - Numpy Array to ArcGIS GRID gives ValueError?

I have a numpy array saved to disk ( the numpy array is a depth image from a Kinect 360) and I want to convert that numpy array to an ESRI GRID. I have the simple code below to accomplish that task but I get the following error:

Traceback (most recent call last): 
File "C:\gTemp\Text-1.py", line 4, in myRaster = arcpy.NumPyArrayToRaster(myarray,(0.0,0.0),1.0, 1.0, -99999.0 )


File "C:\Program Files (x86)\ArcGIS\Desktop10.4\ArcPy\arcpy__init__.py", line 2299, in NumPyArrayToRaster return _NumPyArrayToRaster(*args, **kwargs) ValueError: Argument in_array: A two or three dimensional NumPy array is required.

I am new to numpy and do not understand why I am getting this error. I am using ArcGIS 10.4

import arcpy
import numpy
myarray = r"E:\depthtester2.npy"
myRaster = arcpy.NumPyArrayToRaster(myarray,(0.0,0.0),1.0, 1.0, -99999.0 )
myRaster.save("E:\deptht")

Answer

Assuming r"E:\depthtester2.npy" is a saved array, use numpy.load to avoid the ValueError, and as noted in the comments, you need to pass a point object to NumPyArrayToRaster or you'll get a TypeError.

myarray = numpy.load(r"E:\depthtester2.npy")
myRaster = arcpy.NumPyArrayToRaster(myarray,arcpy.Point(0.0,0.0),1.0, 1.0, -99999.0 )
