I have script that imports arcpy, then calls a python subprocess which also imports arcpy:
import arcpy import subprocess cmd = [r'C:\Python27\ArcGISx6410.4\python', 'test.py'] subprocess.check_call(cmd)
import arcpy print 'imported!'
When I run
C:\Python27\ArcGISx6410.4\python call.py, I get an import error:
ImportError: DLL load failed: %1 is not a valid Win32 application.
The stack trace (full text below) suggests that the 32 bit version of ArcPy is being called. Is it possible to call a 64 bit subprocess that imports arcpy from a 64 bit process that also imports arcpy?
I'm able to run this successfully if the subprocess is called using 32 bit python. Any idea why this isn't possible using 64 bit?
