(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
点子版本:

(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

Conda 4.10 与 python 3.10 不兼容。
您无法使用 conda 安装许多软件包的原因是 conda 4.10 具有处理 python 3.10 的已知错误。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.
作为一种解决方法，您仍然可以尝试使用 pip。
