+## Too many environment variables?

+Try `.cargo/config.toml` ([cargo book](https://doc.rust-lang.org/cargo/reference/config.html#env)).
+
+Instead of setting the environments in your shell, you can manually add them to your `.cargo/config.toml`:

+```toml
+[env]
+LD_LIBRARY_PATH = "/absolute/path/to/libtorch/lib"
+LIBTORCH = "/absolute/path/to/libtorch/libtorch"
+```
+

+LD_LIBRARY_PATH = "/absolute/path/to/libtorch/lib:$LD_LIBRARY_PATH"
+LIBTORCH = "/absolute/path/to/libtorch/libtorch"
+EOF

+This will automatically include the old `LD_LIBRARY_PATH` value in the new one.
