Warning message: Failed to install Torch, manually run install_torch(). C:\Users...\Documents\R\win-library\4.1\torch\deps\lantern.dll - %1 is not a valid Win32 application.
Looks like an issue with underlying dependencies for the package. Consider installing PyTorch outside of RStudio and then try reinstalling the R package and see if that makes a difference.
Pytorch was already installed using conda in an environment via:
conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch

It seems that you are using 32 Bit version of R and that's why it's not working. Switching to the 64bit version should make it work.
