I get this error whenever i run my code. the code itself is supposed to move my robot's arm in the given position. can anyone tell me what's wrong? why do i get this error when ive already called the rospy.init?

#!/usr/bin/env python
import rospy
import baxter_interface
from baxter_interface import Limb
import sys
import rospy
import numpy as np
import roslib

class arm_to_pos:

  def __init__(self):
    self.left_arm = Limb('left')

  def move_arm(self):
        'e1':0.75,'w0':0.0,'w1':1.26,'w2':0.0}), timeout = 15.0)

def main():
  position = arm_to_pos()
  rospy.init_node('arm_to_pos', anonymous=True)

if __name__ == '__main__':

Nevermind, fixed it. Had to initialize before assigning position to my class

Place the rospy.init command before you assign you call your class. i.e. switch the order of the first two lines in the main function
