TensorFlow 的 JupyterLab 环境

TensorFlow 准备 JupyterLab 交互式笔记本环境，方便我们边写代码、边做笔记。

基础环境​

以下是本文的基础环境，不详述安装过程了。

Ubuntu​

CUDA​

  • CUDA 11.2.2
    • cuda_11.2.2_460.32.03_linux.run
  • cuDNN 8.1.1
    • libcudnn8_8.1.1.33-1+cuda11.2_amd64.deb
    • libcudnn8-dev_8.1.1.33-1+cuda11.2_amd64.deb
    • libcudnn8-samples_8.1.1.33-1+cuda11.2_amd64.deb

Anaconda​

conda activate base

安装 JupyterLab​

Anaconda 环境里已有，如下查看版本：

jupyter --version

不然，如下进行安装：

conda install -c conda-forge jupyterlab

安装 TensorFlow​

创建虚拟环境 tf，再 pip 安装 TensorFlow：

# create virtual environment
conda create -n tf python=3.8 -y
conda activate tf

# install tensorflow
pip install --upgrade pip
pip install tensorflow

测试：

$ python - <<EOF
import tensorflow as tf
print(tf.__version__, tf.test.is_built_with_gpu_support())
print(tf.config.list_physical_devices('GPU'))
EOF

Solution: Could not load dynamic library 'libcusolver.so.10'​

cd /usr/local/cuda/lib64
sudo ln -sf libcusolver.so.11 libcusolver.so.10

安装 IPython kernel​

在虚拟环境 tf 里，安装 ipykernel 与 Jupyter 交互。

# install ipykernel (conda new environment)
conda activate tf
conda install ipykernel -y
python -m ipykernel install --user --name tf --display-name "Python TF"

# run JupyterLab (conda base environment with JupyterLab)
conda activate base
jupyter lab

另一种方式，可用 nb_conda 扩展，其于笔记里会激活 Conda 环境：

# install ipykernel (conda new environment)
conda activate tf
conda install ipykernel -y

# install nb_conda (conda base environment with JupyterLab)
conda activate base
conda install nb_conda -y
# run JupyterLab
jupyter lab

最后，访问 http://localhost:8888/ ：
