How Can L Uninstall PyTorch?

I can't find any command to uninstall and remove all PyTorch dependencies. Even on the pytorch.org website. I installed PyTorch with conda install pytorch torchvision cuda80 -c sou

Solution 1:

From the anaconda docs, you can uninstall with conda uninstall

Try

conda uninstall pytorch torchvision cuda80 -c soumith

Alternatively, the pytorch docs suggest

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

Solution 2:

Here's the correct set of commands according to CONTRIBUTING.md from the pytorch github repo:

---

Uninstall all existing pytorch installs

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

Solution 3:

You can also use

conda remove torch torchvision

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

P.S. conda uninstall is an alias to conda remove.

Solution 4:

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

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:

• 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:

to delete all unneeded packages:

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

to delete all unneeded tar.bz2 / conda

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

to delete all together

    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.

Solution 5:

You can safely delete the pytorch installation using the following conda command:

conda uninstall pytorch-cpu torchvision-cpu pytorch
