PointFlow : 3D Point Cloud Generation with Continuous Normalizing Flows
Great repo, thank you! I have seen that you have another repo for rendering the point cloud for visualisation but cannot see how you created animations. Would it be possible...
When I trained PointFlow on shapenet airplane class, it was stuck during training after epoch 9. Does anybody know how to solve this problem? 
Hi, could you provide the latent space visualization with t-SNE as written in the paper? Thanks :)
Hi, thanks for releasing the code. I tried to run ` CUDA_VISIBLE_DEVICES=0 ./scripts/shapenet_airplane_gen_test.sh` and get the following numbers: ``` #JSD:0.049739675370807035 #{'1-NN-CD-acc': 0.5679012537002563, # In table 1: 1-NN-CD=75.68 # '1-NN-EMD-acc': 0.5827160477638245,...
I'm trying to understand [`divergence_approx`](https://github.com/stevenygd/PointFlow/blob/fd00fce0daa37453a1469c669a83c44bfb54c44d/models/odefunc.py#L9). I am not sure what exactly it is trying to compute, I suppose something related to the trace of the Jacobian, that is equation 7...
Hello, I have tried all scripts and everywhere I have the same issue. Traceback (most recent call last): File "train.py", line 272, in main() File "train.py", line 268, in main...
Since the torchdiffeq has updated recently, the torch has to update to >1.3. Otherwise, the old torch does not have promote_types function. When I updated the torch, I got the...
I added the flow block in the PointFlow to my model. Then, the bug happened. I tried `torch.cuda.empty_cache()` and `del recon_loss` , but not work. 
I have a 3D point cloud, which the number of each sample is vary. And i met the mismatch in shape problem during the back propagation, while i set the...
