C3D Model for Keras

This is the C3D model used with a fork of Caffe to the Sports1M dataset migrated to Keras. Details about the network architecture can be found in the following arXiv paper:

Tran, Du, et al. "Learning Spatiotemporal Features With 3D Convolutional Networks." Proceedings of the IEEE International Conference on Computer Vision. 2015.

When using json model here is the error
ValueError: Improper config format:

When using previously created model (by adding layers manually) to lead h5 file weights here is the error
ValueError: You are trying to load a weight file containing 0 layers into a model with 11 layers.

Looks like the weights files cant be decoded properly. Any Idea on what to do?

@supun-kanda Based on this project: https://github.com/axon-research/c3d-keras
I created an updated version of the model (for keras 2.2.4): https://github.com/aslucki/C3D_Sport1M_keras
and weights.

Hi, I am facing this error. Did anyone else face this issue?

---

AttributeError Traceback (most recent call last)
in
22 weights_b = np.array(layer.blobs[1].data, dtype=np.float32)
23 weights_p = np.array(layer.blobs[0].data, dtype=np.float32).reshape(
---> 24 layer.blobs[0].num, layer.blobs[0].channels, layer.blobs[0].length,
25 layer.blobs[0].height, layer.blobs[0].width
26 )

AttributeError: length

I am new to caffe and getting attributes from blob using hpp files is sort of not understandable to me here.
Thanks in advance.

@albertomontesg
Is there any training code for the sports-1m dataset?

how can we use the C3D features to model violence detection on videos?
