Condon on multiprocess

[DanielGoldfarb]

This is my first time using codon. I have a python script using python's multiprocess module running 8 processes to keep my 8 cores busy. It runs fine with python, but takes about 3.5 minutes to run.

With codon I get:

$ codon run ssm_multiprocess.py
ssm_multiprocess.py:1:8-20: error: no module named 'multiprocess'
ssm_multiprocess.py:2:8-14: error: no module named 'pandas'
random.codon:263:13-16: error: name 'INF' is not defined
$

Any ideas what I can do to fix this issue?

The message indicates that you misspelled the name of the multiprocessing library. In fact
from python import multiprocessing works just fine for me. (But of course, I prefer @par from codon.)

[DanielGoldfarb]

There are two different multiprocessing libraries ...

Take a look:

https://www.google.com/search?q=multiprocess+vs+multiprocessing+python

The failure occurs with both. This appears maybe to be some kind of a path issue such that Condon can't find the library.

It looks like you are trying to import the multiprocess library as a Codon module (file) rather than a Python library.

See https://docs.exaloop.io/codon/interoperability/python
Use from python import multiprocess

@elisbyberi thanks. I will try that.
