Should I change the code or downgrade opencv?

kochsebastian commented 4 years ago

What opencv version are you using?

nirmalveer commented 4 years ago

opencv-contrib-python-headless 4.2.0.34

kochsebastian commented 4 years ago

As you can see in requirements.txt or environment.yml I was using opencv 3.4. Maybe there was a change in the findContours() function you are free to change the code and stay with opencv 4.2 but there maybe other versioning problems then

Do you have a discord where I can directly chat with you? I have a few more questions

kochsebastian commented 4 years ago

I won't hold your hand while you set this project especially not with these easy questions. Try to learn to read error messages and you can fix problems by yourself
