Is there a way to run Paddle Serving without GPU or on Colab?

[l03126]

I've been finetuning my rec model on Colab/ Kaggle with GPUs on those platforms. Is there a way to run it on a device without GPU or is there a workaround to get it to work on Colab/ Kaggle? I'm just looking to test the service feature out.

Yes, you can run Paddle Serving without a GPU, and there are also workarounds to test the service on platforms like Colab or Kaggle.

Running Paddle Serving Without a GPU

1. Install the CPU Version of PaddlePaddle:
   If you're working on a device without a GPU, you need to install the CPU version of PaddlePaddle. For example:

   pip install paddlepaddle

   This ensures that PaddlePaddle will use the CPU for computation.

2. Set Paddle Serving to Use the CPU:
   Paddle Serving will automatically work on the CPU if the GPU is not available. However, you can explicitly set the device to CPU in your serving configuration or environment variables.

3. Performance Consideration:
   Running models on the CPU will be slower than on a GPU. For small-scale testing or deploying lightweight models (such as MobileNetV3), the CPU should suffice.

Running Paddle Serving on Colab or Kaggle

Colab and Kaggle provide free GPUs, but you can also run your service without GPU or specifically test Paddle Serving on these platforms. Here’s how:

1. Install Paddle Serving on Colab or Kaggle:
   Use the following commands to install Paddle Serving and its dependencies:

   !pip install paddle-serving-server # For CPU
   !pip install paddle-serving-client

   If you want to use a GPU on these platforms:

   !pip install paddle-serving-server-gpu
   !pip install paddle-serving-client

2. Testing Paddle Serving Without GPU:

   • Even if a GPU is available in Colab or Kaggle, you can force Paddle Serving to use the CPU by installing the CPU version of PaddlePaddle and its serving components as shown above.
   • Ensure that your PaddlePaddle version matches the platform's compatibility.

3. Using Paddle Serving on Colab/Kaggle with GPU:
   If you want to test with a GPU on these platforms:

   • Ensure Colab/Kaggle runtime is set to use a GPU.
   • Install the GPU version of PaddlePaddle and Paddle Serving (paddle-serving-server-gpu).
   • Check GPU usage with a command like:

     !nvidia-smi

Workaround for Testing the Service Feature

If your goal is just to test the service feature:

1. Use a lightweight model like MobileNetV3. Such models are optimized for low-resource environments, making them feasible to run on a CPU.
2. Test on a small subset of data to reduce computational load.
3. Use Colab/Kaggle for quick deployment and testing without worrying about hardware limitations.

Related Issues and Discussions

While the provided GitHub discussion (#14057) is focused on GPU utilization during training, it highlights that PaddlePaddle can operate in both CPU and GPU modes. This flexibility extends to Paddle Serving as well, and you can seamlessly switch to the CPU if needed.
