Cuda 11.6 deprecated

[AGPatriota]

I updated the r-base and torch recently (UBUNTU 18.04). The last version seems not to be compatible with cuda version 11.6

✖ Unsupported CUDA version "11.6"

Do not understand why. I am trying to downgrade to find the last version that accepts cuda version 11.6

LibTorch is very finicky to support older CUDA versions (actually also for newer versions too) so we have a very small range of versions supported.

I recommend installing torch using the pre-buiilt binaries from. Those bundle CUDA and CUDNNN versions required by torch, so you don't need to manage a CUDA installation.

You can install them with somehting like:

kind <- "cu118"
version <- "0.12.0"
options(repos = c(
  torch = sprintf("https://torch-cdn.mlverse.org/packages/%s/%s/", kind, version),
  CRAN = "https://cloud.r-project.org" # or any other from which you want to install the other R dependencies.
))
install.packages("torch", type = "binary")

I got it with:

install.packages("https://cran.r-project.org/src/contrib/Archive/torch/torch_0.11.0.tar.gz", repos = NULL, type = "source")

It is installing the additional packages.

require('torch')

ℹ Additional software needs to be downloaded and installed for torch to work correctly.

I have to change my GPU.

Thanks
