How to load pretranid 3D model?

[fengwhu]

@chuckcho I want to load the pre-trained Sport1m model via net = caffe.Classifier(MODEL_FILE, PRETRAINED) in video-caffe. I used the prototxt file provided by you in #facebookarchive/C3D#59, but I failed to load the 3D model conv3d_deepnetA_sport1m_iter_1900000. I wonder how to modify the prototxt file if using function net = caffe.Classifier() in video-caffe?

[chuckcho]

It doesn't look like a trivial task to use a model generated by different Caffe (facebook/C3D) because there have been fundamental changes in blob definitions, and etc. If I have a good Sport1m or UCF101 model trained using video-caffe later, I'll share it.

[fengwhu]

@chuckcho Thank you!

[fengwhu]

@chuckcho Excuse me. I wonder if the good Sport1m or UCF101 model is available for video-caffe. Could you share it?

[chuckcho]

Yes. Will share it when I have a good one. Thanks.

Hi, all. I have transplanted a model from the original conv3d_deepnetA_sports1m_1900000 model. I tried to make a fork from the master, but when i tried to upload the model file, it reminds me the file is too big so i can't do it. How could i deal with this problem? @chuckcho.

[attitudechunfeng]

I don't check its correctness, but I've uploaded the model file to onedrive and you guys can get it from the link below:

[chuckcho]

@attitudechunfeng, awesome! will try this out. thanks for your contribution.

[fengwhu]

@attitudechunfeng Sorry. I still can't load the transplanted Sport1m model with its 'deploy.prototxt' file by net = caffe.Classifier(MODEL_FILE, PRETRAINED) in video-caffe. The python console gets error: It seems the kernel died unexpectedly. Use 'Restart kernel' to continue using this console.

[attitudechunfeng]

@fengwhu I've not tried python interface before, however, when i use command interface it works well. Maybe you can try the command way.

[fengwhu]

@attitudechunfeng Could you share your command interface codes for this?

[attitudechunfeng]

@fengwhu for example, if you'd like to fine-tune the pre-trained model. First, u need to write a "train_test.prototxt" like the "deploy.prototxt", also with a "solver.prototxt". Make sure all the path in above files right. Then run the command
../../build/tools/caffe train --solver=solver.prototxt --weights=../../conv3d_deepnetA_sport1m_iter_1900000.caffemodel
u can make a try.

[fengwhu]

@attitudechunfeng I write a "train_test.prototxt" with a "solver.prototxt" and run the command just as you said. But I am getting the following error when using conv3d_deepnetA_sport1m_iter_1900000.caffemodel

[haohao900618]

@fengwhu Hello, I encountered the same problem like you. Did you have solved it. If you have solved the problem, please share your experience here! Thank you very much!

[fengwhu]

@haohao900618 Sorry, I haven't solved the problem yet.

[mzolfaghari]

@attitudechunfeng Is it possible to provide your train.prototxt? Because I get same error as @haohao900618 and @fengwhu.
Also, why did you set number of outputs in your deploy.prototx to 1? ( num_output: 1)

Thanks,

[mzolfaghari]

@chuckcho Could you please share your trained models? specially, trained models on sport1m dataset.

Best,

[chuckcho]

unfortunately i don't have trained models on Sports1m.

[mzolfaghari]

@chuckcho , @fengwhu , @haohao900618 :
Maybe this could be interesting for you: https://gist.github.com/bearpaw/5c38196a3f0c755621b8
converting new caffemodel to old caffe!

Best,

[chuckcho]

@mzolfaghari cool. thx.

[chuckcho]

For those who follow this thread, I've posted a sport1m-pretrained model. Look here for the detail: #21 (comment)

[icbcbicc]

@attitudechunfeng Sorry to bother, I want to use a model which I have already trained to classify some videos. I follow your suggestions but I still encounter some problems. Is the train_test.prototxt" same with the "deploy.prototxt"? What's more, can you share your solver.prototxt?
Thanks.

[icbcbicc]

@chuckcho
In order to classify some videos after training, I use ./build/examples/cpp_classification/classification.bin together with the deploy.prototxt given above, but it seems that it only supports image input.
What should I do to get the labels?
Thanks.

[chuckcho]

@icbcbicc i don't have a python script for that, but you can prepare test video as in UCF-101 example, and use test script.

[icbcbicc]

@chuckcho I have tried this test script before, but it only outputs the accuracy of each iteration rather than the labels.

[pelun]

Everyone can help me step-by-step what I can do after I download source code "video-caffe". I want to run this project. When I run extract_UCF-101_frames.sh, I modified directory but it show error syntax in /. Thanks
