About extraction of 3D feature

[BBBoundary]

Hello！I'm trying to use your project code to test my own video. Thanks for providing the code to extract the features. We import the models in 3D-ResNets-Pytorch demo you linked into the misc folder, but we have the following problems when extracting 3D features:

Traceback (most recent call last): File "./misc/extract_featsmotion.py", line 82, in model, = generate_model(opt) File "/media/louyu/DATA/SAAT/misc/model.py", line 51, in generate_model n_classes=opt.n_classes) File "/media/louyu/DATA/SAAT/misc/models/resnext.py", line 66, in generate_model **kwargs) File "/media/louyu/DATA/SAAT/misc/models/resnext.py", line 53, in init shortcut_type, n_classes) File "/media/louyu/DATA/SAAT/misc/models/resnet.py", line 132, in init shortcut_type) File "/media/louyu/DATA/SAAT/misc/models/resnet.py", line 189, in _make_layer downsample=downsample)) TypeError: init() got an unexpected keyword argument 'in_planes'

I wonder how to solve this problem. Thanks!

Hi, the feature is from the layer before the last fc-layer. I made two changes

Hope this can help~

Thanks for your quick reply~ But unfortunately we are new to this field, so we still can't this problem. We modified the code according to your help but it still reported the previous error. We guess there's something wrong with the previous code or we misunderstood your method. Since we don't have much experience in coding of Deep Learning, we hope we can learn from solving this problem. So it'll be highly appreciated if you can send the models files(resnet.py, resnext.py etc.) to our email@culaccino_9350@163.com QAQ!!

Hello,sir. When I try the code you open to extract motion features, I have the same problem.

TypeError: init() got an unexpected keyword argument 'in_planes

May you give the model file such as resnet.py resnext.py to the email 1552981316@qq.com. Thank you very much,sir

Hi,have you solved this problem?

Hi, I uploaded the files in 3D-ResNets-Pytorch/models @tangyuhao2016
