Python Compatibility Issue

[jseldred]

This morning I encountered a new set of warnings and errors.

The set imports at the beginning of the synergia file I am running generate warnings: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88

Another error raised: ImportWarning: Not importing directory '/home/vagrant/.pyenv/versions/py2/lib/synergia': missing __init__.py I decided to use 'touch' to create an empty __init__.py file in the directory that it was expected, and this error message went away.

After progressing past the __init__.py error message, I encounter: AttributeError: 'module' object has no attribute 'utils' which would be the first line in which the synergia imports are used. In this case the import is supposed to come from the line: from rssynergia.base_diagnostics import utils

I think may be related to Python 2 / Python 3 compatibility issues because that seems to be a common thread when I google-troubleshoot the errors messages.

How should I proceed?

Thank you.

We are just ignoring the numpy error, because as you note, it's a known error without a solution. It doesn't seem to affect anything.

For the synergia import error, how are you running python? I don't see that error either in a notebook or on the command line on the jupyter server.

I am running synergia through command line synergia IRCS_SC_WB.py or mpiexec -n 16 synergia IRCS_SC_WB.py

The lines of code that are run before the error interrupts:

import sys, os
import numpy as np
import matplotlib as mpl
mpl.use('pdf')
import matplotlib.pyplot as plt
import random
import scipy
from scipy.optimize import newton
from scipy import constants

    import tables
except ImportError:
    get_ipython().system(' pip install tables')
from mpi4py import MPI

I'm not seeing the error. Perhaps try to restart your server.

Contact me offline, and perhaps we can debug over Skype or Hangouts.

[jseldred]

The restart worked, I'm not seeing the problem anymore.

I thought I had ruled that out because I restarted yesterday morning, but it has apparently worked.

Great, thanks for letting us know!
