(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

O.S.: 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？

Answer 1

您是否尝试过升级 pip？
它适用于以下命令和版本：

$python--版本

 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

Answer 2

Conda 4.10 与 python 3.10 不兼容。

你不能用 conda 安装很多包的原因是 conda 4.10 有一个已知的错误处理 python 3.10。将您的 conda 更新到 4.11 或将您的 python 恢复到 3.9 或更早版本。 Read more here in this SO answer.

作为解决方法，您仍然可以尝试使用 pip。
