Python 如何卸载 PyTorch？

How can l uninstall PyTorch?

提问by vincent

I can't find any command to uninstall and remove all PyTorch dependencies. Even on the pytorch.orgwebsite.

我找不到任何卸载和删除所有 PyTorch 依赖项的命令。甚至在pytorch.org网站上。

I installed PyTorch with

我安装了 PyTorch

conda install pytorch torchvision cuda80 -c soumith

From the anaconda docs, you can uninstall with conda uninstall

从anaconda docs，您可以卸载conda uninstall

Try

尝试

conda uninstall pytorch torchvision cuda80 -c soumith

Alternatively, the pytorch docssuggest

或者，pytorch 文档建议

conda uninstall pytorch
pip uninstall torch
pip uninstall torch # run this command twice

You can also use

你也可以使用

conda remove torch torchvision

Please note that this will removethe specified packages (here: torch and torchvision) and any other package which depends on torch and torchvision, if there're any.

请注意，这将删除指定的包（此处：torch 和 torchvision）以及任何其他依赖于torch 和 torchvision 的包（如果有）。

P.S. conda uninstallis an alias to conda remove.

PSconda uninstall是conda remove.

I recently found a good tool!

我最近发现了一个好工具！

pip install pip-autoremove

This tool can delete all the tools you need to delete. For example, if you need to delete the torch, then it can delete torchvision as well!

这个工具可以删除所有你需要删除的工具。例如，如果您需要删除torch，那么它也可以删除torchvision！

Usage: pip-autoremove [OPTION]... [NAME]...

Options:
  --version     show program's version number and exit
  -h, --help    show this help message and exit
  -l, --list    list unused dependencies, but don't uninstall them.
  -L, --leaves  list leaves (packages which are not used by any others).
  -y, --yes     don't ask for confirmation of uninstall deletions.

Perhaps @Schütze meant with "This does not remove all the files." that there are still files in the Anaconda\pkgs folder.

也许@Schütze 的意思是“这不会删除所有文件”。Anaconda\pkgs 文件夹中仍有文件。

Mind that you can remove the tar.b2 and the folder of the now unused packages in Anaconda\pkgs. I uninstalled pytorch cuda version (because my display driver does not support cuda) and there were huge files there:

请注意，您可以删除 tar.b2 和 Anaconda\pkgs 中现在未使用的包的文件夹。我卸载了 pytorch cuda 版本（因为我的显示驱动程序不支持 cuda）并且那里有大文件：

• pytorch-1.5.0-py3.7_cuda102_cudnn7_0.tar.bz2
• pytorch-1.5.0-py3.7_cuda102_cudnn7_0
• cudatoolkit-10.2.89-h74a9793_1.conda
• cudatoolkit-10.2.89-h74a9793_1

• pytorch-1.5.0-py3.7_cuda102_cudnn7_0.tar.bz2
• pytorch-1.5.0-py3.7_cuda102_cudnn7_0
• cudatoolkit-10.2.89-h74a9793_1.conda
• cudatoolkit-10.2.89-h74a9793_1

This makes 3 GB altogether! Either do this manually, or with a command:

这总共有 3 GB！手动执行此操作，或使用命令执行此操作：

to delete all unneeded packages:

删除所有不需要的包：

    conda clean --yes --packages --dry-run

to delete all unneeded tar.bz2 / conda

删除所有不需要的 tar.bz2 / conda

    conda clean --yes --tarballs --dry-run

to delete all together

一起删除

    conda clean --yes --all --dry-run

First use parameter --dry-run to see what will happen. Afterwards, run without --dry-run. This has cleaned about 3.5 GB of the used 7 GB disk space that was used by Anaconda\pkgs.

首先使用参数 --dry-run 看看会发生什么。之后，在没有 --dry-run 的情况下运行。这已经清除了 Anaconda\pkgs 使用的 7 GB 磁盘空间中的大约 3.5 GB。
