Would you try checking the versions of pytorch and torchvision. Their versions should correspond to each other. – NiKS

Not sure if you are installing the correct versions of the libraries. This combination seems to work:

conda create --name test5 python=3.6
conda install -c pytorch pytorch torchvision cpuonly
python
>>> import torchvision
