errors of running SVR test inference

[Bingoang]

Hi,Julian

I really appreciate your great work! I want to run the SVR test inference, but met some problems: I downloaded your SVR trained model "checkpoint_epoch_6.tar" , and the input data "test_inference_example". And I make the folder "if-net-master/experiments/iPC3000_dist-0.5_0.5_sigmas-0.2_0.015_v256_mSVR/checkpoints", and put the "checkpoint_epoch_6.tar" "BMan0201-HD2-O04P05-S_3DSV_H250_W250_res256.npz" "BMan0201-HD2-O04P05-S_3DSV_H250_W250_res256.off" all in the folder. Then I run the command: python generate.py -pointcloud -pc_samples 3000 -std_dev 0.2 0.015 -res 256 -m SVR -checkpoint 6 -batch_points 100000 But something goes wrong:

I'm really new to this, and I hope you can give me some advice. Thanks a lot!

Hi, you're welcome - looks good.

I'm currently working on a deadline but will come back to you after that. I'll update the code with logic for loading the checkpoint. Might take until start of December though.

Best, Julian

@jchibane Sounds great! Thank you for your reply and look forward to your update!!

Hi

I was wondering where I can download the test_inference_example. I only found the pretrained models.

[kfarivar]

I just looked at the generate.py code and saw that the dataset is literally created by a function in the voxelized_data_shapenet.py so it is not surprising it is not working for the single view point cloud input and SVR model. hope we can get the single view human point cloud inference script soon.

Oh, there may be something wrong with github. You commented 7 days ago, but it just shows now.╭( T □ T )╮ I downloaded the test_inference_example in this issue: https://github.com/jchibane/if-net/issues/5

Hi all,

I gave you some bits and pieces in Issue #27 that should get you started - I'd also like to include official support for own point clouds in IF-Nets. A PR is welcome or I might do it myself at some point when I find some more time hopefully.

Best, Julian

Will leave the issue open as a feature request.

I get the same error: No such file or directory: 'shapenet/data/04379243/e834ef941f7bc9c9e7df9f1005942e3d/boundary_0.1_samples.npz' or No such file or directory: 'shapenet/data/02958343/b0945cdea946d1a363c65629bee30ef9/voxelization_32.npy' while running generate.py or train.py: FileNotFoundError: [Errno 2] No such file or directory: 'shapenet/data/02958343/25de320e58cb3898f43db49cede9f847/voxelization_32.npy'

Can someone please help me. Thanks.
