Error occured when trying to finetune the pre-trained model on hmdb51

Hey, I am trying to finetune the model on hmdb, but when I run the scripts tools/train_net.py, an error occured. Do you know how to fix it? Which version of caffe2 do you use, the official caffe2 or your personal fork of caffe2?

Did you mean: []

@wenjie710 the latest caffe2 should have VideoInputOp (https://github.com/pytorch/pytorch/tree/master/caffe2/video)

Thanks very much! It works now.

@wenjie710 Can you write how you solved this issue, please? I also see the error message now..

Unfortunately Caffe2 will need to be built from source in order to include an OpenCV and ffmpeg dependency required for those operators to be built. The binary install doesn't include these because we didn't want the additional dependencies. cc @pjh5
