I have a simple script to test multiprocessing with arcpy, but the script hang indefinitely. The problem is with the import arcpy
statement that seems to be a problem in the child processes. Other multiprocessing script without import arcpy
are working correctly
import arcpy import multiprocessing import os, sys multiprocessing.set_executable(os.path.join(sys.exec_prefix, 'python.exe')) def testExists(data): print data return arcpy.Exists("foo.gdb") if __name__ == '__main__': data = ["foo.gdb", "bar.gdb"] pool = multiprocessing.Pool(2) result_arrays = pool.map(testExists, data) print result_arrays pool.close() pool.join()
Any idea what can cause the problem?
