When attempting to import ArcPy into ArcGIS Pro, the import statement returns the following error message:
Error: ImportError: DLL load failed: %1 is not a valid Win32 application.
The ArcGIS Pro 64-bit Python interpreter is attempting to import a 32-bit module, as the Environment Variable 'PYTHON' or 'PYTHONPATH' is referencing a folder containing the ArcMap 32-bit ArcPy module.
import sys for path in sys.path: print (path)
Note: The script loops through each path the Python interpreter references for modules. If the generated lists include the ArcMap 32-bit ArcPy module, move to Step 2.
