ImportError: cannot import name '_C'

After adding C++ API, I tried to install torchvision both way.

pip install -v .
python setup.py install

Installation is successful.

However, when I import torchvision, I got following error.

(Server Spec: Ubuntu 16.04 , Cuda 10 + cudnn 7 , NVIDIA V100 GPU, PyTorch Nightly (13 May, 2019))

There has probably a problem with your install. Can you try uninstalling torchvision, and reinstall it again?

python setup.py clean
python setup.py install

sorry, i already installed previous version (vision v0.2.2) and started training model.
Next time, I will try this and leave comment. Thank you.

under the 'vision' directory,
python -c "impor torchvision" produced import error.
However, under the other directory. it doesn't
(vision v0.2.2 has no import error even under the vision directory
of course it's because there is not C++ api)
Thank you.

I fixed this error. You could add _C.cpython-36m-aarch64-linux-gnu.so to the file 'torchvision'(it's just for jetson nano)
