如何安装最新版本的TensoFlow 2? [英] How to install the latest version of TensoFlow 2?

问题描述

我想知道为什么我不能安装 TensorFlow 2.0.0 (到目前为止是稳定的版本 )

I am wondering that why I cannot install the TensorFlow 2.0.0 (stable version until now in their official website even in PyPi)

我曾经使用过TensorFlow 2.0.0b1版本，但是由于我的numpy版本与TensorFlow不兼容，所以我正在处理一些警告.它是1.17并且必须是1.16.4(

I used to had the TensorFlow 2.0.0b1 version, but I was dealing with several warnings because my numpy version wasn't compatible with the TensorFlow. It was 1.17 and must be 1.16.4 (Reference). Hence, I downgrade it but TensorFlow didn't work anymore. So I decide to reinstall the TensorFlow latest stable version as mentioned above.

到目前为止，我已经完成了:

Here is I've done so far:

pip install -U tensorflow

它从pip show tensorflow退回1.14

pip install tensorflow

它从pip show tensorflow退回1.14

pip install tensorflow==2.0
pip install tensorflow==2.0.0
pip install 'tensorflow>=2' 

他们抛出以下错误:
