When I write these two lines in ArcGIS Pro v1.3.1 Python window I get the result shown below the dotted line. However if I run them one at a time I get the anticipated result. What is going on? By the way, the lines are part of a bigger project, and it seems like anything inserted in line 2 yields an error. I don't suspect that the GPX file is corrupted since it runs with success in example 2 below. It also runs with success with the GPXtoFeatures tool in ArcGIS.
arcpy.GPXtoFeatures_conversion("D:\Downloads\TrackLog2.gpx", "in_memory/GPX")
print("HelloWorld")
