It should be the opencv version

I used the Q2 command and succeeded

Q1.pip install transforms3d
Q2.python -m pip install opencv-contrib-python, and then follow @yangbenbo 's advice, this problem is done(thank you).
Q3.after the two qusetion, Q3 is normal automaticaly.I just want to test the single node to debug(rqt_easy_handeye), thanks for your advice, it works.
