通过Conda安装PyTorch [英] Installing PyTorch via Conda

问题描述

目标:使用pytorch和torchvision创建一个conda环境. Anaconda Navigator 1.8.3，python 3.6，MacOS 10.13.4.

Objective: Create a conda environment with pytorch and torchvision. Anaconda Navigator 1.8.3, python 3.6, MacOS 10.13.4.

我尝试过的事情:

• 在Navigator中，创建了一个新环境.尝试安装pytorch和torchvision，但由于用户界面搜索软件包找不到与pytorch，torch，torchvision或类似字符串匹配的任何可用软件包，因此无法进行安装.
• conda install pytorch torchvision -c pytorch
• conda update --all

• In Navigator, created a new environment. Tried to install pytorch and torchvision but could not because the UI search for packages does not find any packages available matching pytorch, torch, torchvision, or similar strings.
• conda install pytorch torchvision -c pytorch
• conda update --all

pytorch 0.3.1，torch 0.3.1和torchvision 0.2.0现在显示为在根环境中安装.但是，根环境不再是可克隆的.克隆按钮为灰色/禁用(以前是启用/可克隆).我可以将根环境用作后备环境，但是conda的主要目的是能够创建单独的且可处理的环境.我想念什么?

pytorch 0.3.1, torch 0.3.1, and torchvision 0.2.0 now appear as installed in the root environment. However, the root environment is no longer cloneable; the clone button is gray/disabled (it used be enabled/cloneable). I could use the root environment as a fallback but the main point of conda is to be able to create separate and disposable environments. What am I missing?

更新-----------------

UPDATE -----------------

运行conda install -c pytorch pytorch会产生: # All requested packages already installed.但是，如果我激活了pytorch环境并在其中列出了软件包，则没有包含单词"torch"的软件包.如果再执行conda search pytorch，我将得到PackagesNotFoundError: The following packages are not available from current channels: - pytorch.如果我激活base环境然后执行conda list，则pytorch在基本软件包列表中.那么如何创建一个包含pytorch的单独环境?

Running conda install -c pytorch pytorch yields: # All requested packages already installed. But if I activate the pytorch environment and list the packages therein, there is no package containing the word "torch". If I then do conda search pytorch I get PackagesNotFoundError: The following packages are not available from current channels: - pytorch. If I activate the base environment and then do conda list then pytorch is in the package list for base. So how does one create a separate environment containing pytorch?

推荐答案

您似乎已在基本环境中安装了PyTorch，因此无法在其他"pytorch"环境中使用它.

You seem to have installed PyTorch in your base environment, you therefore cannot use it from your other "pytorch" env.

要么:

• 使用PyTorch直接创建一个新环境(简称为pytorch_env):conda create -n pytorch_env -c pytorch pytorch torchvision

切换到已使用以下命令创建的pytorch环境:source activate pytorch_env，然后在其中安装PyTorch:conda install -c pytorch pytorch torchvision

switch to the pytorch environment you have already created with: source activate pytorch_env and then install PyTorch in it: conda install -c pytorch pytorch torchvision
