`method`	Installation method. By default, "auto" automatically finds a method that will work in the local environment. Change the default to force a specific installation method. Note that the "virtualenv" method is not available on Windows (as this isn't supported by PyTorch). Note also that since this command runs without privillege the "system" method is available only on Windows.
`conda`	The path to a `conda` executable. Use `"auto"` to allow `reticulate` to automatically find an appropriate `conda` binary. See Finding Conda for more details.
`version`	PyTorch version to install. The "default" version is 1.4. You can specify a specific PyTorch version with `version="1.2"`, or `version="1.6"`.
`envname`	Name of Python or conda environment to install within. The default environment name is `r-torch`.
`extra_packages`	Additional Python packages to install along with PyTorch. If more than one package use a character vector: `c("pandas", "matplotlib")`.
`restart_session`	Restart R session after installing (note this will only occur within RStudio).
`conda_python_version`	the Python version installed in the created conda environment. Python 3.4 is installed by default. But you could specify for instance: `conda_python_version="3.7"`.
`pip`	logical
`channel`	conda channel. The default channel is `stable`. The alternative channel is `nightly`.
`cuda_version`	string for the cuda toolkit version to install. For example, to install a specific CUDA version use `cuda_version="10.2"`.
`dry_run`	logical, set to TRUE for unit tests, otherwise will execute the command.
`...`	other arguments passed to `reticulate::conda_install()` or `reticulate::virtualenv_install()`.
