介绍

Ubuntu 18.04.5 LTS
GTX 1070
TensorFlow 2.4.1

所需软件

NVIDIA® GPU drivers —CUDA® 11.0 需要 450.x 或者更高版本。
CUDA® Toolkit — TensorFlow 所需 CUDA® 11 (TensorFlow >= 2.4.0)
cuDNN SDK 8.0.4 cuDNN versions。
(Optional) TensorRT 6.0 改善延迟和吞吐量，以在某些模型上进行推理。
Miniconda — 创建虚拟环境。

安装前

GCC

$ gcc --version
Command 'gcc' not found, but can be installed with:
sudo apt install gcc
$ sudo apt install gcc
$ gcc --version
gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0

NVIDIA package repositories

$ wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin
$ sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
$ sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub
$ sudo add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/ /"
$ sudo apt-get update

NVIDIA machine learning

$ wget http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64/nvidia-machine-learning-repo-ubuntu1804_1.0.0-1_amd64.deb

$ sudo apt install ./nvidia-machine-learning-repo-ubuntu1804_1.0.0-1_amd64.deb
$ sudo apt-get update

NVIDIA GPU driver

$ sudo apt-get install --no-install-recommends nvidia-driver-460

注：这里需要使用 460 版本，TensorFlow 官网写的是 450，实测失败。

重启并使用以下命令检查 GPU 是否可见。

安装 JupyterLab 和 matplotlib

$ pip install jupyterlab matplotlib

在 JupyterLab 中运行 TensorFlow

$ jupyter lab

JupyterLab 将自动在浏览器打开。

从 https://www.tensorflow.org/tutorials/images/cnn 下载并导入 CNN notebook。

安装 VSCode

前往官网下载并安装 VSCode。

打开 VSCode 并安装 Python 支持。

image

选择某个文件夹（这里以 ~/tensorflow-notebook/01-hello 为例），新建文件 hello.ipynb。

import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
hello.numpy()

使用 VSCode 打开刚才创建的 ~/tensorflow-notebook/01-hello/hello.ipynb，并选择 Python 为创建的虚拟环境。
