PyTorch installation problem- package not found using Jupyter notebook and Conda navigator
I have tried to install PyTorch using the installation code form official PyTorch website.
I run it locally in the Jupyter notebook on Conda navigator
conda install pytorch torchvision cudatoolkit=10.2 -c pytorch

I received the following mistake
    PackagesNotFoundError: The following packages are not available from current channels:

  - pytorch
  - cudatoolkit=10.2

Current channels:

  - https://conda.anaconda.org/pytorch/win-32
  - https://conda.anaconda.org/pytorch/noarch
  - https://repo.anaconda.com/pkgs/main/win-32
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/win-32
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/msys2/win-32
  - https://repo.anaconda.com/pkgs/msys2/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

What to do?

TL;DR Use 64-bit Anaconda
conda manages packages for one platform and architecture.
It looks like you installed 32-Bit (x86) Win Anaconda version, here:
- https://conda.anaconda.org/pytorch/win-32

You can check that channel under that link (https://conda.anaconda.org/pytorch/win-32) does not contain any pytorch package, and same is for this one: https://conda.anaconda.org/pytorch/noarch
If you look at the win64: https://conda.anaconda.org/pytorch/win-64 it actually contains pytorch packages.
So, there is no pytorch x86 packages in pytorch channels and in addition it is not possible to create environment of another architecture, meaning that you need to install 64-bit Anaconda to use pytorch.
