It seems there is a problem with the conda installation of the 1.0.0 version for cuda 10. If I execute:
/usr/local/anaconda3/bin/conda install -y pytorch=1.0.0 torchvision cudatoolkit=10.0 -c pytorch

Then If executing. I get cuda version 9:
(/tmp/cuda10.0_pytorch_1.0.0/) user@usermachine1:/tmp$ python -c "import torch; print(torch.version.cuda)"
9.0.176
