ImportError: No module named baxter_interface

Hello, I followed the official steps to install the SDK and set up some items that need to be set. I get an error when I execute the code below. Since I have just been exposed to ROS and Baxter, it is not too clear what the reason is. Looking at some of the information did not solve the problem. I hope you can help me. Thank you

import  rospy
import baxter_interface
rospy.init_node('Hello_Baxter')
limb = baxter_interface.Limb('right')
angles = limb.joint_angles()
print angles
angles['right_s0']=0.0
angles['right_s1']=0.0
angles['right_e0']=0.0
angles['right_e1']=0.0
angles['right_w0']=0.0
angles['right_w1']=0.0
angles['right_w2']=0.0
print angles

limb.move_to_joint_positions(angles)
wave_1 = {'right_s0': -0.459, 'right_s1': -0.202, 'right_e0': 1.807, 'right_e1': 1.714, 'right_w0': -0.906, 'right_w1': -1.545, 'right_w2': -0.276}

wave_2 = {'right_s0': -0.395, 'right_s1': -0.202, 'right_e0': 1.831, 'right_e1': 1.981, 'right_w0': -1.979, 'right_w1': -1.100, 'right_w2': -0.448}
for _move in range(3):
    limb.move_to_joint_positions(wave_1)
    limb.move_to_joint_positions(wave_2)
quit()

Error is as follows：
$ python baxter.py
Traceback (most recent call last):
File "baxter.py", line 7, in
import baxter_interface
ImportError: No module named baxter_interface

Thank you very much This issue has been resolved. Just add
source ~/baxter_ws/devel/setup.sh to ~/.bashrc.
