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()
}
