(pgqa) raphy@pc:~/pythonMatters/PathGenerator$ python3 --version
Python 3.10.0

尝试使用 pip 安装 PyTorch，但出现以下错误：

(pgqa) raphy@pc:~/pythonMatters/PathGenerator$ pip3 install torch==1.10.0+cpu 
torchvision==0.11.1+cpu torchaudio==0.10.0+cpu -f https://download.pytorch.org
/whl/cpu/torch_stable.html
Looking in links: https://download.pytorch.org/whl/cpu/torch_stable.html
ERROR: Could not find a version that satisfies the requirement torch==1.10.0+cpu (from versions: none)
ERROR: No matching distribution found for torch==1.10.0+cpu

操作系统：Ubuntu 20.04

pip 版本：

(pgqa) raphy@pc:~$ pip --version
pip 21.2.4 from /home/raphy/anaconda3/envs/pgqa/lib/python3.10/site-packages/pip (python 3.10)
(pgqa) raphy@pc:~$ pip3 --version
pip 21.2.4 from /home/raphy/anaconda3/envs/pgqa/lib/python3.10/site-packages/pip (python 3.10)

Python 版本：

(pgqa) raphy@pc:~$ python --version
Python 3.10.0

如果最新的稳定python版本是3.10，为什么它要求python3.1？ 如何解决问题？

【参考方案1】：

您是否尝试过升级您的pip？ 它适用于以下命令和版本：

$ python --version

 Python 3.8.10

$ pip --version

pip 21.3.1

$ pip install torch==1.10.0+cpu torchvision==0.11.1+cpu torchaudio==0.10.0+cpu -f https://download.pytorch.org/whl/cpu/torch_stable.html

【讨论】：

(pgqa) raphy@pc:~$ pip --version pip 21.2.4 from /home/raphy/anaconda3/envs/pgqa/lib/python3.10/site-packages/pip (python 3.10) (pgqa) raphy@pc:~$ pip3 --version pip 21.2.4 from /home/raphy/anaconda3/envs/pgqa/lib/python3.10/site-packages/pip (python 3.10) (pgqa) raphy@pc:~$ python --version Python 3.10.0 . 你是在建议我同时降级 python 和 pip 吗？

嗨@Raphael10，我已经尝试过使用 pip 21.3.1 和 python 3.8 并且效果很好。在这个阶段，我无法确认 python 3.10.0

是的。似乎问题出在python 3.10.0 : (pgqa) raphy@pc:~$ python --version Python 3.8.10 (pgqa) raphy@pc:~$ pip --version pip 21.1.1 from /home/raphy /anaconda3/envs/pgqa/lib/python3.8/site-packages/pip (python 3.8) (pgqa) raphy@pc:~$ pip3 install torch==1.10.0+cpu torchvision==0.11.1+cpu torchaudio ==0.10.0+cpu -f download.pytorch.org/whl/cpu/torch_stable.html查看链接：download.pytorch.org/whl/cpu/torch_stable.html收集火炬==1.10.0+cpu下载download.pytorch.org/whl/cpu/torch-1.10.0%2Bcpu-cp38-cp38-linux

github.com/pytorch/pytorch/issues/67669 估计3.10还不支持，
