Mask R-CNN configs

Hi, thank you for your great work! Recently we would like to compare your model with ours on the Mask R-CNN results. I wonder if you can provide some configs for Mask R-CNN settings? Thanks!

semantic segmentation code

Hi,thaks for your excellent work!!! I have read your paper named 'Pyramid Vision Transformer: A Versatile Backbone for Dense Prediction without Convolutions', and want to apply it in my work in semantic segmentation, When will you make the semantic segmentation code and models public?

About FLOPs calculation in Table 2

Hi Wenhai, thanks for this great work.

I have few questions about the FLOPs calculation in this paper. Previously I tested the DeiT models with ptflops, I got 2.51G, 9.20G, 35.13G FLOPs for DeiT-Tiny, DeiT-Small, DeiT-Base, respectively.

B.T.W I also included the matrix multiplications in the self-attention layer, namely q @ k and attn @ v. I assume there is something wrong with my calculation, may I know how do you calculate FLOPs for your experiments?

Thanks.

how can i load pickle file?

thanks for sharing the code .. i'm trying to load pickle file to read it using these commands

import pickle infile = open('data.pkl','rb') new_dict = pickle.load(infile) infile.close() print(type(new_dict)) but error is _pickle.UnpicklingError: A load persistent id instruction was encountered, but no persistent_load function was specified. i searched for the solution but got that pickle file appears to be using advanced features that suggest it was never supposed to be directly loaded this way. can you help, please ?

How can I get small_pvt.pth?

I run your main.py .. I'm confusing what this class do ? it gave me the accuracy for 500 epoch and loss of them right ? and when I tried to train my images by this command 'dist_train.sh configs/retinanet_pvt_s_fpn_1x_coco_640.py 1'

I got that small_pvt.pth not found .. excuse me does that will be the weights ? Or checkpoints ?

Does small_pvt.pth here https://drive.google.com/file/d/1vtcyoU8KUqNzktlMGXZrYcMRsNNiVZFQ/view?usp=sharing For imagenet ? But how can I got pth file.if the dataset.is different . Appreciating your reply. Thanks

problems about loading pretrained model with pytorch version below 1.6

problems about loading pretrained model with pytorch version below 1.6

pytorch 1.6 have switched torch.save to use a zip file-based format by default rather than the old Pickle-based format. This cause pytorchs with version below 1.6 can not load the pretained models AT ALL.

Can you use "_use_new_zipfile_serialization=False" when using torch.save()? just like torch.save(m.state_dict(), 'mymodel.pt', _use_new_zipfile_serialization=False). And provide another version of pretrained models?

Thanks a lot!!!!

PVT Large deosn't converge
Thanks for your great work. But when I trained PVT Large (pvt_large) as your default settings, the model didn't converge. The loss declined correctly in the first 37 epochs and the accuracy went to 57% but the model went wrong at 38th epoch. I used your code without any change. What's the problem? Thank you!

Below is a part of my training log.

pretrained model load

hello~, i am very interested in your work. Now i meet some questions when the pretrained model was load checkpoint = torch.load(args.finetune, map_location='cpu')

debug: pos_embed_checkpoint = checkpoint_model['pos_embed'] the checkpiont have "pos_embed1" "pos_embed2" "pos_embed3" "pos_embed4", but no "pos_embed"

Why there is no DETR+PVTv2 in object detection?

I noticed that there is DETR+PVTv1, although its AP value is not satisfactory. Why is there no implementation of DETR+PVTv2? Is it ineffective or just not provided yet.

Did you train PVT on ImageNet22k?

Thank you for your great work! As the title descripted, I want to know about your ImageNet22k results. I saw a checkpoint of PVT_v2_b5 on imagenet_22k in your release. Is that useful?

Question about cls token

Hi author! thanks for your nice work.

I have a question about cls token in PVT.

In ViT and DeiT, cls token is appended at input embedding process. But PVT append cls token at input of last stage.

Why PVT doesn't append cls token at input embedding process?

Thanks.

without Convolutions?

Paper offers convolution free architecture but implementation contains convolution, at pvt2 paper authors says spatial reduction done with conv but I could not see that in pvt1. Is there any other way to do that?

Question about pooling size

Hi @whai362

I was wondering why the pooling size is set to 7 for all stages? Have you tried a higher pooling size (e.g. more keys and values) for the initial stages while decreasing in later stages?

Code of PVTv2 is released! PVTv2 largely improves PVTv1 and works better than Swin Transformer with ImageNet-1K pre-training.
