【超快速教學】如何在Docker環境內使用GPU跑Tensorflow

安裝Nvidia Driver

先不用裝cuda以及cudnn

1. 移除舊的driver

   sudo apt-get purge nvidia*
   sudo apt-get autoremove
   sudo apt-get autoclean
   sudo rm -rf /usr/local/cuda*
   

2. Nvidia官網上面查詢符合目前GPU的驅動版本

   

   以我這台為例是版本510，後面小數點的不用記，我們不在這下載，用apt install比較快。

   

3. 安裝Nvidia driver

   $ sudo apt update
   

   $ sudo apt install nvidia-utils-"剛剛找出來的版號"
   $ sudo apt install nvidia-driver-"剛剛找出來的版號"
   # example
   $ sudo apt install nvidia-utils-510
   $ sudo apt install nvidia-driver-510
   

4. 重新開機

   $ sudo reboot
   

5. 確認安裝成功

   $ nvidia-smi

安裝NVIDIA Container Toolkit

在docker container中使用gpu加速運算必須安裝container toolkit

1. 設定repo以及GPG key

   $ distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
     && curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
     && curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | \
           sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
           sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
   

2. 安裝nvidia-docker2

   $ sudo apt-get update
   $ sudo apt-get install -y nvidia-container-toolkit
   

3. 設定 Docker 識別 NVIDIA Container Runtime

   sudo nvidia-ctk runtime configure --runtime=docker
   

4. 重啟 Docker

   $ sudo systemctl restart docker
   

5. 測試是否安裝成功

   $ sudo docker run --rm --runtime=nvidia --gpus all nvidia/cuda:11.6.2-base-ubuntu20.04 nvidia-smi
   

   出現GPU的訊息就表示安裝成功

在Docker環境中使用GPU跑Tensorflow

1. 拉一個image下來

   $ sudo docker pull tensorflow/tensorflow:latest-gpu
   

2. 使用GPU run起來，會進入到docker的環境裡面

   $ sudo docker run --gpus all -it tensorflow/tensorflow:latest-gpu bash
   

3. 直接import tensorflow確認

   #進入到python console
   $ python 
   

   >>> import tensorflow as tf
   >>> tf.config.list_physical_devices('GPU')
   

   下面訊息確認有抓到GPU

   >>> tf.config.list_physical_devices('GPU')
   2022-03-08 07:08:03.310660: I tensorflow/stream_executor/cuda/cuda_gpu_executor.cc:936] successful NUMA node read from SysFS had negative value (-1), but there must be at least one NUMA node, so returning NUMA node zero
