Not really an issue but a question

[yliu7366]

When creating my own CSV file for keras-maskrcnn training, how many different classes do I have to include? Can I have only one object class such as tumor across all images? Or does it has to be something like 'tumor' vs. 'kidney', meaning at least two object classes? Thank you.

only one class was ok for https://github.com/fizyr/keras-retinanet . I think, here is same situation.

Only one class works, there is no need for a second class.
For this kind of questions it would be better to use our slack channel #keras-maskrcnn, where you can find more appropriate support

@vcarpani I am not able to find keras-maskrcnn workspace. Can you post the URL for the same?

I've just added a line in the README to direct users to the slack channel:
