Custom dataset with less classes?

[chowkamlee81]

I need to train for custom dataset with less classes.
I referred to #2.
But i had a doubt on How to get the values of content:

PolarSeg/semantic-kitti.yaml

Line 72 in 172c650

content: # as a ratio with the total number of points

.

Kindly help

The content in semantic-kitti.yaml is the distribution ratio of classes in the SemanticKITTI dataset. You have to calculate the total number of points of each class in your custom dataset to get this ratio. But, you don't need this information to train PolarSeg unless you want to try some other losses, like weighted cross-entropy.
