I wrote a GUI, for which I used these imports:
import os
import sys
import serial
import scipy
import string
import time
import datetime
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
from collections import deque
from numpy import array
from pylab import xlabel, ylabel, subplot
from scipy.fftpack import fft
from pylab import *
There is a red line below sys and time, I am using pycharm community edition 4.5.3, it is showing the reason for this error is 'no module named sys' and same for time. But when i tried to run it, it works perfectly.
What is the reason behind it and will it affect my code in future?
