AttributeError: 'module' object has no attribute 'drawAxis'

Question

I am working with ros melodic, opencv 4.5.5, ubuntu 18.04. I draw 3 axis of marker aruco to display on rqt_image_view. when running i get this problem AttributeError: 'module' object has no attribute 'drawAxis' Here is the code of my axis plot:

 ......................
    frame_out = aruco.drawAxis( img, self.K, self.distCoeffs, rvecs, tvecs, axisLength)
    ...................
    self.aruco_marker_img_pub.publish(self.bridge.cv2_to_imgmsg(frame_out, "bgr8"))
    .......................

when i do aruco aruco without ros it's normal,when it's right it will look like this

enter image description here

Could you try printing out `aruco.__file__` using `print(armco.__file__)`? I think python could be mistaking a local module with the same name as `aruco` module? — tax evader, Jun 02 '22 at 10:29
Does this help frame_out = cv2.aruco.drawAxis instead of frame_out = aruco.drawAxis? — toyota Supra, Jun 02 '22 at 10:57
I realized that cv2.aruco.drawAxis can't compile in python2 but that conflicts with the tf package. how can i compile tf package with python3 — huytd-pi, Jun 02 '22 at 16:13

I think you meant to use cv2.drawFrameAxes instead of cv2.drawAxes.
