Calling a bash script which uses python and opencv

mpiexec -n 4 python $PY_SCRIPT_PATH $1 $2 $3 $4

The python code uses opencv, cuda, ...:

from sys import argv
import numpy as np
import time
import colorsys

import matplotlib.image as img
import matplotlib.pyplot as plt
import scipy.misc as scipy
import cv2

from Cheetah.Template import Template

import pycuda.compiler as nvcc
import pycuda.gpuarray as gpu
import pycuda.driver as cu

import pycuda.autoinit

from mpi4py import MPI
import math

The matlab terminal outputs

ImportError: /usr/lib/python2.7/dist-packages/cv2.so: undefined symbol: _ZTIN2cv5BRISKE

when I try to run the command. I tried reloading the .bashrc from the script to reset the environment variables with no luck. Does anyone know how to fix it?

bash , ubuntu , python , opencv , cuda
