 ### Test example
 
-When running the GPU Server, you need to set the GPUs used by the prediction service. By default, CPU version is used. You can configure it in two ways:
-
-1. Using the `CUDA_VISIBLE_DEVICES` environment variable, the following example specifies two GPUs with an index of 0 and 1:
-
-   ```shell
-    export CUDA_VISIBLE_DEVICES=0,1
-   ```
-
-2. Using the `--gpu_ids` option, which will overrides the configuration of `CUDA_VISIBLE_DEVICES`.

+When running the GPU Server, you need to set the GPUs used by the prediction service through the `--gpu_ids` option, and the CPU is used by default. An error will be reported when the value of `--gpu_ids` exceeds the environment variable `CUDA_VISIBLE_DEVICES`. The following example specifies to use a GPU with index 0:
+```shell
+export CUDA_VISIBLE_DEVICES=0,1
+python -m paddle_serving_server_gpu.serve --model uci_housing_model --port 9292 --gpu_ids 0

 ### 测试example
 
-在运行GPU版Server时需要设置预测服务使用的GPU，缺省状态默认使用CPU。可以通过下面两种方式进行配置：
-
-1. 使用`CUDA_VISIBLE_DEVICES`环境变量，下面的示例为指定索引为0和1两块GPU：
-
-   ```shell
-    export CUDA_VISIBLE_DEVICES=0,1
-   ```
-
-2. 使用`--gpu_ids`选项，该选项将覆盖`CUDA_VISIBLE_DEVICES`的配置。
