 You can optionally configure your `model_mount_path` value. By adjusting this setting, you can change the path where the model is mounted.

+> [!IMPORTANT]
+> `model_mount_path` is usable only in BYOC (Bring your own container) scenario. In BYOC scenario, the environment that the online deployment uses must have [`inference_config` parameter](#the-inference_config-parameter) configured. You can use Azure ML CLI or Python SDK to specify `inference_config` parameter when creating the environment. Studio UI currently doesn't support specifying this parameter.
 
 When you change the value of `model_mount_path`, you also need to update the `MODEL_BASE_PATH` environment variable. Set `MODEL_BASE_PATH` to the same value as `model_mount_path` to avoid a failed deployment due to an error about the base path not being found.
