Hi, I'm just wondering if other Windows users are having any issues installing/loading the awesome new torch install.packages("torch") and remotes::install_github("mlverse/torch"). Both seem to work fine, but when I run library(torch), I get this:
# trying URL 'https://download.pytorch.org/libtorch/cpu/libtorch-win-shared-with-deps-1.5.0.zip'
# Content type 'application/zip' length 99725651 bytes (95.1 MB)
# downloaded 95.1 MB
# trying URL 'https://storage.googleapis.com/torch-lantern-builds/refs/heads/master/latest/Windows-cpu.zip'
# Content type 'application/zip' length 1436082 bytes (1.4 MB)
# downloaded 1.4 MB
# Warning message:
# Failed to install Torch, manually run install_torch(). C:\Users\ethan\Documents\R\win-library\4.0\torch\deps\lantern.dll - The specified module could not be found.
So then I run install_torch() and get this:
# Error in cpp_lantern_init(normalizePath(install_path())) :
# C:\Users\ethan\Documents\R\win-library\4.0\torch\deps\lantern.dll - The specified module could not be found.
But if I go to that path, it's definitely there:
Any help is greatly appreciated, I'm really not sure where to go from here.

Hi @EeethB
Thanks for trying torch! Can you try the solution proposed in this issue?

Hi @dfalbel & collaborators,
Thank you for bringing "torch" interface to R, … enabling R to have better deep learning capabilities! I was keen to try out all examples in pkgdown website, but when I install "torch", I encounter the following issue, *C:\Users\User\Documents\R\R-4.0.2\library\torch\deps\lantern.dll - The specified module could not be found*:
``` r
remotes::install_github("mlverse/torch")

#> Running `R CMD build`...
#> * checking for file 'C:\Users\User\AppData\Local\Temp\RtmpwHIpeq\remotes11645e5530e6\mlverse-torch-52ded08/DESCRIPTION' ... OK

But when I check for existence of "lantern.dll", it did exist:
``` r
file.exists("C:\\Users\\User\\Documents\\R\\R-4.0.2\\library\\torch\\deps\\lantern.dll")
#> [1] TRUE
```

Could you advice how should I proceed? The following is my sessionInfo:

Hi, that seems to have worked! At least, I can now load torch. Thanks
