Problem importing libraries on RoboDK
Hi there,

I have the Python code below and it works perfectly if i run it without roboDK. If i import it to roboDK and run it from there, it returns me an error (attached image) because of the libraries which are not of roboDK. Do you know how can i solve this?


import cv2                                # state of the art computer vision algorithms library
import numpy as np                        # fundamental package for scientific computing
import imageio                      
import matplotlib.pyplot as plt           # 2D plotting library producing publication quality figures
import pyrealsense2 as rs 
import win32gui
import win32api
import time
import pyautogui
from robolink import *    # API to communicate with RoboDK
from robodk import *      # basic matrix operations
# Any interaction with RoboDK must be done through
RL = Robolink()

points = rs.points()
pipe = rs.pipeline()
config = rs.config()
profile = pipe.start(config)

colorizer = rs.colorizer()
align = rs.align(
state_left = win32api.GetKeyState(0x01)  # Left button up = 0 or 1. Button down = -127 or -128
device = profile.get_device() # type: rs.device
depth_sensor = device.first_depth_sensor() # type: rs.depth_sensor

if depth_sensor.supports(rs.option.depth_units):

robot = RL.Item('UR5e')
frame = RL.Item('Reference Frame')
Target = RL.AddTarget('Target 2', frame)

    while True:
       frames = pipe.wait_for_frames()
       frames = align.process(frames)
       depth_frame = frames.get_depth_frame()
       color_frame = frames.get_color_frame()
       if not depth_frame: continue
       depth = np.asanyarray(colorizer.colorize(depth_frame).get_data())
       color = np.asanyarray(color_frame.get_data())
       images = np.hstack((color, depth))
          #cv2.namedWindow('RGB_View', cv2.WINDOW_NORMAL)
       #cv2.setWindowProperty('RGB_View', cv2.WND_PROP_FULLSCREEN, cv2.WINDOW_FULLSCREEN)
       cv2.imshow('RGB_View', color)
       depth_intrin = depth_frame.profile.as_video_stream_profile().intrinsics
       #flags, hcursor, (x,y) = win32gui.GetCursorInfo()
       x, y = win32api.GetCursorPos()
       #print(x, y)
       pixel_coord = [x, y]
       keypressed = win32api.GetKeyState(0x01)
       key = cv2.waitKey(1)
       # Press esc or 'q' to close the image window
       if key & 0xFF == ord('q') or key == 27:
       #Calculate distance
       if keypressed!=state_left:
        state_left = keypressed
        if keypressed < 0:
         if (0<x<632 and 32<y<512):
          dist_to_center = depth_frame.get_distance(x,y)
          dist_to_center = round(dist_to_center, 4)
          depth_point = rs.rs2_deproject_pixel_to_point(depth_intrin, pixel_coord, dist_to_center)
          depth_point = [i * 100 for i in depth_point]
          depth_point = [round(i, 3) for i in depth_point]
          #depth_point = ( ", ".join( repr(e) for e in depth_point))
          with open('Coordinates.txt', 'w') as f:
            f.write("%s\n" % depth_point)
          #print(depth_point[0:5], depth_point[7:12], depth_point[15:19])
          print('The camera is facing an object:',dist_to_center,'meters away')
          Target.setPose(Offset(eye(), depth_point[0], depth_point[1], depth_point[2], 0, 0, 0))

Hi there,

There is no image attached.

Have a great day.
That's true, here it is,

You should install the Python libraries needed by your application on the Python version you use for RoboDK. This is probably in C:/RoboDK/Python37 (you can find this out in Tools-Options-Other).

Alternatively, you could have a quick workaround by adding this in your code:

from robolink import *

# make sure opencv for python is available
import_install("cv2", "opencv-python")

# Load OpenCV
import cv2
