anaconda+pytorch安裝

1. anaconda安裝

官網下載Anaconda3-5.0.1-MacOSX-x86_64.pkg 點擊安裝

安裝完成後，可使用anaconda navigator,包括jupyter和spyder

2. pytorch安裝

官網的點擊是無響應的，根據提示使用終端，輸入

conda install pytorch=0.2.0 -c soumith

詢問是否肯定安裝而且對響應對包update，選擇y，回車。

安裝完畢，以下

3. 問題

使用conda install pytorch=0.2.0 -c soumith這個命令只是安裝torch(指定版本)，而沒有torchvision

 

使用conda install pytorch torchvision -c soumith將會安裝torch 和 torchvision

沒有cuda就不指定其版本，且不須要指定python的版本，具體安裝以下：

 

anenyangdeMacBook-Air:~ Anenyang$ conda install pytorch torchvision -c soumith
