After having no luck with various manual build manuals for Caffe2 and OpenCV (within my anaconda python 2.7 environment, Ubuntu 16.04), I followed the advice to install the nightly build binaries via:
conda install pytorch-nightly torchvision -c pytorch
I want to use models from R2Plus1D for extracting action recognition features. However, when running their
extract_features.py it will throw the following error message:

Some issues mention that there is a simple solution. Does somebody know a solution?
