Different features for each run? #14
Comments
I have tried to load the occo weights for the pointnet model (for the semantic segmentation task). However, some weights are missing ({'module.conv4.weight', 'module.conv4.bias', 'module.feat.stn.conv1.weight', 'module.feat.conv1.weight'} |
Hi @katadam, the provided pre-trained weight is from the completion pre-training task, for encoding an object you don't need to load the entire classification version of the PointNet |
Thanks for the answer @hansen7 . Yes, I have noticed that, however, I want to extract features for a semantic segmentation. This is why I am loading PointNet (local and global features aggregated). To obtain the weights for this task, I should finetune on a semantic segmentation dataset (s3dis, Scannet), the models you are providing or pre-train the whole PointNet ? |
we have many downstream tasks, I cannot provide all the fine tuned weights for all of them。。。 |
@hansen7 thanks for your answer! |
It is on the same location of the google drive。。。namely, |
Thanks @hansen7 , ok, it is clear now. I was wondering if you had a model for pre-trained on shape completion for the whole point net model (the one you are providing + the transformation networks). But I will use the one for part segmentation (namely, {modelname}_occo_seg.pth), finetune it on s3dis to get the weights for the extra layers and use that as an encoder to my other dataset to extract semantic segmentation features. |
Hello and thanks for the terrific code.
I have one question, I am trying to use OcCo pretrained network on the semantic segmentation task to extract features and perform dense matching of 3d points (either Pointnet or pcn).
I have saved and I am loading the same h5 file to avoid alternations due to different sampling. However, if I run the encoder twice (with the same tensor as points), I do not get determenistic results and the returned feature tensors are different, without changing anything. I am in mode model.eval() to have a defined dropout. Could you elaborate please?
