The cfg file doesn't work.

[Frank-Dz]

I want to train the network with 1 channel input and 4 classes.
I followed：

#192

Here, I modified the classes= 4. and change the filter. But my network still takes 3 channels until I set

    output_filters = [1]  # input channels

in model.py

Seems like the yolov3-spp.cfg does not make a difference for model creation.
If it is not the right way, how can we modify the training scheme to support 1 channel input and 4 classes?
