Explainanbility for S3DIS

[suurajroshan]

Thank you for making your code public. I'm trying to implement your code for S3DIS and had some questions. If I'm not wrong in the RandLANet the code

        cam = PowerCAM(net, batch_data, cfg, norm=True, cls=8, mode='counterfactual', mask_type='none')
        num_points = cam.runCAM()
        print(num_points)

is what computes the heatmaps? From what I was able to interpret, the rest of the code was for the training of SemanticKitti model, whereas I already have a trained S3DIS model.

(Also, if it helps I'm implementing the same for the DGCNN model.)
