I have already installed ros noetic distribution and the sudo apt-get install ros-noetic-cv-bridge and sudo apt-get install ros-noetic-cv-bridge successfully. However, when I am trying to run the following code in pycharm, I am getting the following error:
import os
import argparse
import pdb
import cv2
import rosbag
from sensor_msgs.msg import Image
from cv_bridge import CvBridge
bag_file = './bag_files/20230707_152832.bag'
output_dir= './frames/rgb_bag_output'
image_topic = '/device_0/sensor_1/Color_0/image/data'
# image_topic ='sensor_msgs/Image'
bag = rosbag.Bag(bag_file, "r")
bridge = CvBridge()
#gg =bag.read_messages(topics = '/device_0/sensor_1/Color_0/image/data')
# bag.get_message_count()
count = 0
for topic, msg, t in bag.read_messages(topics=image_topic):
cv_img = bridge.imgmsg_to_cv2(msg, desired_encoding= "rgb8")#"passthrough")
cv2.imwrite(os.path.join(output_dir, "frame%06i.png" % count), cv_img)
print("Wrote image %i" % count)
count += 1
bag.close()
the error:
Traceback (most recent call last):

How can I resolve this issue?
