For some reason I have to use one channel images as inputs, but the rknn toolkit does not support one channel darknet model's quantization.So I convert the darknet model to a tensorflow model and it works well before.However, today I try the yolov4 tiny model in this way, and the rknn toolkit return above error.It seems like dose not support the tf.split function.I hope you guys can support more functions and notice the problem of one channel darknet model's quantization.Tanks.

NPU Team repeat:
We have successfully converted darknet offical edition yolov4-tiny (3-channels version) to rknn with rknn-toolkit 1.4.0.
Please try it. And your LOG looks can not support the op "split_2" in tf-edittion.
