python - 当conda尚未支持时，如何在Windows上安装最新的Tensorflow(在此处为: 2. 2)？

Question

我在Windows 8.1上有conda 4.8.3和Python 3.7.4。
我在conda环境中安装了tf 2.0.0。如何升级到2.2.x？
或者，如何在conda环境中安装2.2.x？
编辑1:pip install --upgrade tensorflow说:Requirement already up-to-date: tensorflow in d:\anaconda3\envs\tf2\lib\site-packages (2.1.0)但是TF版本仍然是2.0。
编辑2:conda install tensorflow == 2.2.0说:

PackagesNotFoundError: The following packages are not available from current channels:

tensorflow == 2.2.0

我确实有一些运气 here。

Answer 1

有两种方法
1.使用以下命令安装到虚拟环境中

pip TensorFlow

virtualenv --system-site-packages -p python3 ./venv

那么您需要激活您的新环境

pip install --upgrade pip

pip list  # show packages installed within the virtual environment
this command for quit 
deactivate  # don't exit until you're done using TensorFlow
we finish by installing tensor 

pip install --upgrade tensorflow

2.在您的系统中安装

python3 --version
pip3 --version
virtualenv --version

的Ubuntu

sudo apt update

sudo apt install python3-dev python3-pip

sudo pip3 install -U virtualenv  # system-wide install

然后

pip3 install --user --upgrade tensorflow  # install in $HOME
