pytorch 以前的版本在我的本地机器上安装冲突
pytorch previous version installation conflict in my local machine
我正在尝试在 python 2.7 环境
中使用以下 conda 命令安装 PyTorch 和 Torchvision
conda install pytorch==1.1.0 torchvision==0.3.0 -c pytorch
但是出现这个错误，
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- torchvision==0.3.0 -> python[version='>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']
Your python: python=2.7
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.
The following specifications were found to be incompatible with each other:

我针对特定 python 2.7 环境的 conda 列表是
# Name Version Build Channel
ca-certificates 2021.1.19 haa95532_0
certifi 2020.6.20 pyhd3eb1b0_3
pip 19.3.1 py27_0

wheel 0.36.2 pyhd3eb1b0_0
wincertstore 0.2 py27hf04cefb_0
我尝试将 sqlite 升级到 3.33.0，但它正在显示
All requested packages already installed.
当我尝试卸载 sqlite 时，整个 python 环境包都被卸载了。
请有人帮助我。
PyTorch 从未为 Python 2.7 构建 Windows 这些版本的 PyTorch 和 TorchVision。可以为此使用 conda search：
$ conda search 'pytorch[channel=pytorch,subdir=win-64,version=1.1]'
Loading channels: done
# Name Version Build Channel
pytorch 1.1.0 py3.5_cuda100_cudnn7_1 pytorch
pytorch 1.1.0 py3.5_cuda90_cudnn7_1 pytorch
pytorch 1.1.0 py3.6_cuda100_cudnn7_1 pytorch
pytorch 1.1.0 py3.6_cuda90_cudnn7_1 pytorch
pytorch 1.1.0 py3.7_cuda100_cudnn7_1 pytorch
pytorch 1.1.0 py3.7_cuda90_cudnn7_1 pytorch
至少你必须使用 Python 3.5，但如果你要使用 Python 3 并且需要那些特定的 PyTorch 版本，你也可以跳转到 Python 3.7.
conda create -n pytorch_1_1 -c pytorch python=3.7 pytorch=1.1 torchvision=0.3
