我现在应该怎么做才能安装 PyTorch?

What should I do now to install PyTorch?

我几乎尝试了谷歌上提到的所有方法.我在 Ubuntu 上工作，我也尝试使用 conda，但我无法在 conda 之外使用该软件包.

I tried almost every method mentioned on google. I am working on Ubuntu, I tried using conda too, but I am unable to use that package outside conda.

推荐答案

对于 pip 环境使用这个

For pip environment use this

pip3 install torchvision

对于 conda 环境使用这个(在 anaconda 提示符下运行这个命令)

For conda environment use this (run this command on anaconda prompt)

conda install PyTorch -c PyTorch

更新

使用此代码关闭缓存

Update

Use this code to turn off your cache

pip3 --no-cache-dir install torchvision

或

pip3 install torchvision--no-cache-dir

或

pip install --no-cache-dir torchvision

一个一个试试
