I have done your installation setup step-by-step, but unfortunately the train from scratch bash file not working. this is the log file that code have generated on the output file

Hi,

I have trained PS-ViT-Ti/14 following the default setting in the code. But the performance is only 74.6, which is lower than 75.6 in the paper. Could you show more training details?

Thansk for your great work. I tried to train PS-ViT on my own dataset based on your ImageNet pretrained model. But when I use create_model(initial_checkpoint) in your code to load ps_vit_b_18.pth.tar, something goes wrong. Can you help me solve this problem? Thansk again!

Hi, Xiaoyu This PS-ViT is an excellent work! And I have a little question want to ask: When I train the sampling location offsets network, the output offsets are always very high (nearly the H/W of the image) or low (nearly 0). Have you ever encountered this kind of problem？ How do you limit the range of the learned offsets?

Looking forward to your reply! Thanks!

Thank you for your awesome work. I have followed all steps for training your model; however, I encountered the following error which happens for importing your model in line 9 of main.py (import models). Although it seems that models have not been used anywhere in main.py, when I commented import models, another error would occur in line 315 in create_model of main.py.

I would be grateful if you could guide me to deal with this issue.

Hello! I installed under the instructions (PyTorch==1.7.1 and torchvision==0.8.2 with CUDA==10.1). When I install apex using "pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./", it successfully finished. However, when I run the code, there is an error from "import apex", that is "fused_weight_gradient_mlp_cuda module not found. gradient accumulation fusion with weight gradient computation disabled." Have anyone met this problem? Thank you very much!

This PS-ViT is an excellent work! I am confused. Why not use the function torch.nn.functional.grid_sample in pytorch, but use cuda code to implement it by yourself? What is the difference between them?

In your code: sample_feat = self.sampler(x, point, offset)

It seems that CNN stem can effect the model performance, but in Table 7, you just compare PS-ViT with the vanilla ViT. Have you ever tried to compare your PS-ViT with the same CNN stem equipped ViT?

Hello,

Thank you for sharing. I have some problems downloading pre training weights. I hope to get your help. I can't use Google drive to download ps-vit-b / 14 and ps-vit-b / 18 pre training weights. I hope you can provide Baidu online disk and other download methods.Thank you very much.

excuse me i'm facing this problem This program was compiled against version 3.9.2 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.17.1). Contact the program author for an update. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library. (Version verification failed in "bazel-out/k8-opt/bin/tensorflow/core/framework/tensor_shape.pb.cc".)
