[Python知识库]conda安装pytorch

?1、卸载虚拟环境

conda uninstall -n novelgnn --all

2、conda安装虚拟环境?

conda create -n Novelgnn python=3.7

3、安装pytorch

电脑只能安装cpu版本的，安装pytorch实际上就是安装torch和torchvision两个包，下载链接：https://download.pytorch.org/whl/torch_stable.html

?

下载好两个文件之后，存储在某个盘，安装

pip install d:\Anaconda\torch-1.5.0+cpu-cp37-cp37m-win_amd64.whl

pip install D:\Anaconda\torchvision-0.6.0+cpu-cp37-cp37m-win_amd64.whl

检查torch安装是否成功，输入python进入

import torch

torch.__version__

4、项目还需要安装torch-scatter?和?torch-sparse?

下载链接https://pytorch-geometric.com/whl/

pip install D:\Anaconda\torch_scatter-2.0.5-cp37-cp37m-win_amd64.whl

pip install D:\Anaconda\torch_sparse-0.6.7-cp37-cp37m-win_amd64.whl
