get_install_libs_url: Install Torch from files

Description

List the Torch and Lantern libraries URLs to download as local files in order to proceed with install_torch_from_file().

Installs Torch and its dependencies from files.

Usage

get_install_libs_url(version = NA, type = NA)
install_torch_from_file(version = NA, type = NA, libtorch, liblantern, ...)

Arguments

version

Not used

type

Not used. This function is deprecated.

libtorch

The installation archive file to use for Torch. Shall be a "file://" URL scheme.

liblantern

The installation archive file to use for Lantern. Shall be a "file://" URL scheme.

...

other parameters to be passed to "install_torch()"

Details

When "install_torch()" initiated download is not possible, but installation archive files are present on local filesystem, "install_torch_from_file()" can be used as a workaround to installation issue. "libtorch" is the archive containing all torch modules, and "liblantern" is the C interface to libtorch that is used for the R package. Both are highly dependent, and should be checked through "get_install_libs_url()"

Examples

if (torch_is_installed()) {
if (FALSE) {
# on a linux CPU platform 
get_install_libs_url()
# then after making both files available into /tmp/
Sys.setenv(TORCH_URL="/tmp/libtorch-v1.13.1.zip")
Sys.setenv(LANTERN_URL="/tmp/lantern-0.9.1.9001+cpu+arm64-Darwin.zip")
torch::install_torch()
}
}
