This isn't a repo for MaskRCNN.

[Aida da Silva]

This is the demo from MaskRCNN and I keep getting the same error ValueError: None values not supported.

[Aida da Silva]

Hi Jordan Pierce, I am using MaskRCNN repo from Matterpoart on github, this is the error I got from running the demo. I would appreciate if you have some suggestions on how to go about it. Thanks, Aida

Hi @AidaSilva, yes I see that this is code for Matterport's MaskRCNN implementation in Keras, however this repository is qubvel's semantic segmentation repository. It might be more helpful for you to post your issues in Matterport's repo instead.

But since we're already here: looking at the error it seems that something is unutilized and is equal to None when it should be something else. I'd recommend checking your config and MODEL_DIR variables first. It's also possible that you're using different versions of Tensorflow, Keras, and other dependencies that Matterport's code relies on. Can you confirm you're using the correct requirements?

Hi Jordan, Thank you for writing back to me. I am using the newest version of tf and Keras. I am able to run the demo.
