ubuntu如何安装pytorch

pytorch新版本对api有较大改动，0.40版以后已经取消了Variable的类型，并入tensor。所以从官网获取最新版本很有必要。

打开官网PyTorch

pip install http://download.pytorch.org/whl/cpu/torch-0.4.1-cp27-cp27mu-linux_x86_64.whl
pip install torchvision
# if the above command does not work, then you have python 2.7 UCS2, use this command
pip install http://download.pytorch.org/whl/cpu/torch-0.4.1-cp27-cp27m-linux_x86_64.whl
