Not working on keras with "image_data_format": "channels_first"

[OligerMan]

I use a library that only works with image_data format channels_first and your library works only with channels_first.
When you try to init detector from the example with keras settings "image_data_format": "channels_last" you will get error from screenshot
Python 3.8
Tensorflow 2.3.1
Keras 2.4.3
