TypeError: __init__() got an unexpected keyword argument 'dtype'

i trained a 1 class tiny yolo model on a custom dataset (https://github.com/experiencor/kangaroo) using this repo https://github.com/experiencor/keras-yolo2 and received the following error when performing coreml conversion

TypeError: __init__() got an unexpected keyword argument 'dtype'

What line number and in which file does that error occur?

i converted the sample tiny-yolo-voc.h5 to coreml without issue, so the problem should be on my custom model, or should i use this repo to train my custom model instead https://github.com/thtrieu/darkflow

This sounds like you're using an incompatible version of Keras. Unfortunately, Keras changes a lot between one version and the next. Since this is a relatively old repo, I'd suggest updating the yad2k package that is inside it.
