Method VideoInput is not a registered operator

[DuJiajun1994]

I use Pre-Built Binaries to install Caffe2 (conda install -c caffe2 caffe2-cuda8.0-cudnn7). During feature extraction, I get an error as following. Why is VideoInput not registered?

Traceback (most recent call last): File "tools/extract_features.py", line 292, in main() File "tools/extract_features.py", line 287, in main ExtractFeatures(args) File "tools/extract_features.py", line 118, in ExtractFeatures devices=gpus, File "/home/dujiajun/anaconda2/envs/caffe2/lib/python2.7/site-packages/caffe2/python/data_parallel_model.py", line 32, in Parallelize_GPU Parallelize(*args, **kwargs) File "/home/dujiajun/anaconda2/envs/caffe2/lib/python2.7/site-packages/caffe2/python/data_parallel_model.py", line 208, in Parallelize input_builder_fun(model_helper_obj) File "tools/extract_features.py", line 94, in input_fn use_local_file=args.use_local_file, File "/home/dujiajun/R2Plus1D/lib/utils/model_helper.py", line 120, in AddVideoInput data, label, video_id = model.net.VideoInput( File "/home/dujiajun/anaconda2/envs/caffe2/lib/python2.7/site-packages/caffe2/python/core.py", line 2067, in getattr ",".join(workspace.C.nearby_opnames(op_type)) + ']' AttributeError: Method VideoInput is not a registered operator.

Make sure that you compile caffe2 correctly and set the LIBRARY_PATH and PYTHON_PATH correctly point to caffe2. Please check https://caffe2.ai/docs/faq.html
