Using PyKX in Python Subprocesses

This page outlines using PyKX in a Python subprocess.

To use PyKX in a subprocess of a process which has already imported PyKX, you must use the reimporter module.

Failing to use the reimporter can cause the subprocess to crash with a segmentation fault.

Python

Spawn the process using the kx.PyKXReimport function as follows:

Python

Copy 
import pykx as kx
import subprocess
with kx.PyKXReimport():
    subprocess.Popen(['python', 'file.py']) #_Run a python subprocess that loads a python script containing a PyKX import

q

Spawn the process using the .pykx.safeReimport function as follows:

q

Copy 
q)\l pykx.q
q).pykx.safeReimport[{system"python -c 'import pykx as kx'";til 5}]
0 1 2 3 4
