Why is there a dot before cv2 in import? `from cv2 import *` and not `from .cv2 import *` – Vishnudev Krishnadas Nov 18 '18 at 10:03
@Vishnudev THat's an interesting Q. It's within the init file – jason Nov 18 '18 at 10:05
from .cv2 import * from .data import * # wildcard import above does not import "private" variables like __version__ # this makes them available globals().update(importlib.import_module('cv2.cv2').__dict__) – jason Nov 18 '18 at 10:05
Oh okay. This is a new thing to learn. Cool. – Vishnudev Krishnadas Nov 18 '18 at 10:06
But you are right! THat's the error! How can I run it without/updating the init file?? – jason Nov 18 '18 at 10:08
Could you try using the `-m` option provided by python to run the code? `python3 -m app.py` If you are expecting it to behave as a module rather than a single script – Vishnudev Krishnadas Nov 18 '18 at 10:11
I did this : CMD ["python3 -m app.py"] – jason Nov 18 '18 at 10:22
I got this error : python3: can't open file 'python3 -m app.py': [Errno 2] No such file or directory – jason Nov 18 '18 at 10:22
Should be `CMD ["app.py", "-m"]` or `CMD ["python3", "-m", "app.py"]` – Vishnudev Krishnadas Nov 18 '18 at 10:24
I tried the above command : **CMD ["python3", "-m", "app.py"]** and i got this error **(null): can't open file 'python3': [Errno 2] No such file or directory** – jason Nov 18 '18 at 14:13
Y am I getting this error? – jason Nov 18 '18 at 14:14
because your working directory is /app you need to be in python interpreter location to run script using python – Vishnudev Krishnadas Nov 18 '18 at 14:20
I did not get what u meant. Can you write down the code for the same. – jason Nov 18 '18 at 14:30

`apt-get install libglib2.0-0` didn't work. `apt-get install libgtk2.0-dev` worked for me. – Shinebayar G Sep 16 '19 at 05:46
`apt-get install libgtk2.0-dev -y` worked for me, since I have included this code in the dockerfile. – Edwin Varghese Feb 13 '20 at 06:23
