import error when using packages of python

Question

Can some one please help me with this error. I am using Ubuntu 20.04 and jupyter notebook. (I have directly installed project jupyter from ubuntu app store. I don't have anaconda installed with it or spyder.)

I have tried following but nothing worked at

!pip install opencv-python

sudo apt-get install python3-opencv

apt update && apt install -y libsm6 libxext6 libxrender-dev

Strange thing is if write the same code in other python file and run it through terminal it's working. But I am unable to run the same code in Jupyter Notebook

ImportError                               Traceback (most recent call last)
<ipython-input-1-c8ec22b3e787> in <module>
----> 1 import cv2

/home/adarsh/snap/jupyter/common/lib/python3.7/site-packages/cv2/__init__.py in <module>
      3 import sys
      4 
----> 5 from .cv2 import *
      6 from .data import *
      7 

ImportError: libSM.so.6: cannot open shared object file: No such file or directory

Have you tried updated and install the libraries? `apt update && apt install -y libsm6 libxext6 libxrender-dev` — cdutra, Jul 29 '20 at 17:53
Can you check which python you use in the terminal an which one you use in your ipython notebook? — Marc, Jul 29 '20 at 18:26
may i see your cv2 file ??? Just try with space from .(dot)cv2 import * — Sumit Yadav, Jul 29 '20 at 18:30
@SumitYadav I am getting this while trying your method ModuleNotFoundError: No module named '__main__.cv2'; '__main__' is not a package — Adarsh, Jul 29 '20 at 18:32
It says No Such File Directory, which means it is unable to find the CV2 file — Sumit Yadav, Jul 29 '20 at 18:33
@Marc Will you please tell me how can I know whether they are pointing to the same one or not please.. — Adarsh, Jul 29 '20 at 18:36
Does this answer your question? [ImportError: libSM.so.6: cannot open shared object file: No such file or directory](https://stackoverflow.com/questions/47113029/importerror-libsm-so-6-cannot-open-shared-object-file-no-such-file-or-directo) — vmemmap, Jul 29 '20 at 18:40
@SumitYadav from cv2 import * didn't worked either , i am getting the same error again — Adarsh, Jul 29 '20 at 18:43

you can actually use jupyter notebook itself to install

conda install opencv

!pip install opencv-python-headless
# also contrib, if needed
