诸神缄默不语-个人CSDN博文目录
TensorFlow是学习深度学习时常用的Python神经网络框架，本文将介绍其部分版本在Linux系统使用pip进行安装的方法。
（注：TensorFlow官方推荐使用pip进行安装。）
作者使用anaconda作为管理虚拟环境的工具。以下工作都在虚拟环境中进行，对Python和Aanaconda的安装及对虚拟环境的管理本文不作赘述，后期可能会撰写相关的博文。
首先进入官网：TensorFlow
TensorFlow安装的总界面：Install TensorFlow 2
官方安装指南：Install TensorFlow 2
用pip安装的指南：Install TensorFlow with pip
TensorFlow基础的系统环境等要求可直接在该网站上查看，已经2022年了，一般电脑都不会这么老吧。
新建anaconda虚拟环境：conda create -n envtf2 python==3.8（Python版本需要是3.7-3.10，本文以3.8为例，主要是因为我需要用3.8版本来安装另一个包）
激活虚拟环境：conda activate envtf2
如果要使用cuda，首先确定本机安装有NVIDIA GPU driver：nvidia-smi（一般都会有的吧，没有的话到得了这一步吗）
安装指定的cudatoolkit和cudnn版本：conda install -c conda-forge cudatoolkit=11.2 cudnn=8.1.0
有两种指定配置路径的方式：
①临时的，每次会话都需要先激活虚拟环境然后：export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CONDA_PREFIX/lib/
②自动在每次激活虚拟环境后执行此操作（我没有试过，我一直都用的是上面那种方式）：
mkdir -p $CONDA_PREFIX/etc/conda/activate.d
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CONDA_PREFIX/lib/' > $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh
更新pip：pip install --upgrade pip
安装TensorFlow：pip install tensorflow
检验CPU版TensorFlow是否可用：python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
（我的服务器有4张卡）
检验GPU版TensorFlow是否可用：python3 -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))"
注意，以上操作是在终端上进行的，不能直接放到jupyter notebook。一个失败的例子：
在jupyter notebook上，我直接调用!export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CONDA_PREFIX/lib/也不行，用os.environ['LD_LIBRARY_PATH']也不行，用$env也不行，就把我整得相当困惑。我看了一下，好像如果用jupyter notebook的话就必须要修改jupyter内核才能用，但是我修改了jupyter kernelspec list路径中的kernel.json后仍然不行。（参考自python - How to set env variable in Jupyter notebook - Stack Overflow）
其他我在网上有看到一些使用全局配置解决此问题的方法，但是我这个服务器上还需要运行别的版本的别的项目，总之不太方便用这个。一般来说我对此问题的解决方法就是不用jupyter notebook来跑TF项目。我看的这些资料可资参考：
解决TensorFlow在terminal中正常但在jupyter notebook中报错的方案 - stardsd - 博客园
Add CUDA Library Path to Jupyterhub Notebook - AIML - wiki.ucar.edu
install pytorch with jupyter - 知乎
所以jupyter notebook上要成功使用TensorFlow GPU功能的话就必须要先在命令行上激活虚拟环境，然后export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CONDA_PREFIX/lib/，然后调用jupyter notebook命令打开jupyter notebook，这样就能直接正常使用了。
（注意：如果仅安装了ipykernel包，那么VSCode中可以打开notebook文件，但是无法使用jupyter notebook打开能够在浏览器中打开的网页，因此需要安装jupyterlab：pip install jupyterlab（参考Project Jupyter | Installing Jupyter）。VSCode即使在远程服务器上也可以把端口转到本地使用localhost域名在本地浏览器打开，挺方便的）
运行成功的效果：
这个是苏神bert4keras（https://github.com/bojone/bert4keras）的配置。
见TensorFlow官网（使用 pip 安装 TensorFlow），仅TensorFlow2.2以上支持Python3.8以上，所以我需要一个Python3.7的环境。
新建anaconda虚拟环境：conda create -n envtf114 python=3.7 pip
安装GPU版TensorFlow：pip install tensorflow-gpu==1.14
试用如下代码（来自tensorflow-gpu1.14代码测试_爱听许嵩歌的博客-CSDN博客_tensorflow-gpu测试代码）：
import tensorflow as tf
with tf.device('/cpu:0'):
a = tf.constant([1.0, 2.0, 3.0], shape=[3], name='a')
b = tf.constant([1.0, 2.0, 3.0], shape=[3], name='b')
with tf.device('/gpu:2'):
c = a + b
# 注意：allow_soft_placement=True表明：计算设备可自行选择，如果没有这个参数，会报错。
# 因为不是所有的操作都可以被放在GPU上，如果强行将无法放在GPU上的操作指定到GPU上，将会报错。
sess = tf.Session(config=tf.ConfigProto(allow_soft_placement=True, log_device_placement=True))
# sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
sess.run(tf.global_variables_initializer())
print(sess.run(c))
报错：

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates
嗯虽然不知道发生了什么总之我从善如流地照着改（参考1. Downgrade the protobuf package to 3.20.x or lower._weixin_44834086的博客-CSDN博客）：
pip install protobuf==3.19.0
然后重新运行代码，这回的输出信息变成了：

其他略，总之那一堆无法打开so文件就说明cuda安装有问题，无法使用GPU。
TensorFlow版本对应GPU版本（图源https://www.tensorflow.org/install/source#gpu）：
所以首先安装所需的cudnn和cuda：conda install -c conda-forge cudatoolkit=10.0 cudnn=7.4
报了个非常诡异的bug：

不知道发生了什么，总之换一种安装方式好了（参考TensorFlow-gpu安装和测试（TensorFlow-gpu1.14+Cuda10）_爱学习的小龙的博客-CSDN博客_tensorflowgpu测试）：
wget -P files/install_packages https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64/cudatoolkit-10.0.130-0.conda

重新运行Python代码。和之前一样的输出部分就不写了，直接从不一样的地方开始：

运行TensorFlow代码时需要在代码前加上这些：
import tensorflow as tf
import os
os.environ["CUDA_DEVICE_ORDER"] = "PCI_BUS_ID"
os.environ["CUDA_VISIBLE_DEVICES"] = "2" #这里是gpu的序号，指定使用的gpu对象
config = tf.ConfigProto()
config.gpu_options.allow_growth = True
Keras就自动安装好了。
直接用bert4keras代码来举个实际用例：
pip install bert4keras
wget -P /data/pretrained_model/chinese_L-12_H-768_A-12 https://storage.googleapis.com/bert_models/2018_11_03/chinese_L-12_H-768_A-12.zip
unzip /data/pretrained_model/chinese_L-12_H-768_A-12/chinese_L-12_H-768_A-12.zip -d /data/pretrained_model/chinese_L-12_H-768_A-12
