错误"Keras需要TensorFlow 2.2或更高版本". [英] Error "Keras requires TensorFlow 2.2 or higher"
问题描述
我刚刚安装了Visual Studio 2019和Tensorflow，但是由于出现以下错误消息，所以无法导入Keras:
I just installed Visual Studio 2019 and Tensorflow, but I cannot import Keras because I get the following error message:
Keras需要TensorFlow 2.2或更高版本.通过
pip install tensorflow
问题是我除了安装Tensorflow 1.15外别无选择，因为我有以下设置:
The problem is that I had no choice but to install Tensorflow 1.15, because I have the following setup:
- Visual Studio 2019
- Python 3.7
- CPU i7 920(无avs，仅SSE)
- OS Windows 7 64
- Nvidia GPU
- CUDA 10.1
我必须下载并安装该Python版本，我的CPU和那个名为"tensorflow-1.15.0-cp37-cp37m-win_amd64"的CUDA版本的轮子.
I had to download and install a wheel for that Python version, my CPU, and that CUDA version named "tensorflow-1.15.0-cp37-cp37m-win_amd64".
Tensorflow似乎可以正常工作(它检测到我的GPU并显示"hello world"消息)，但问题是Visual Studio安装了最新版本的Keras.
Tensorflow seems to work (it detects my GPU and prints a "hello world" message) but the problem is that Visual Studio installs the newest version of Keras.
如何指定较旧的兼容版本，以及较新的版本兼容?
How can I specify an older, compatible version, and what is the newer version compatible?
推荐答案
我上次发布keras时也遇到了同样的问题，我记得did():
I had the same issue caused by last keras release,what i remember did():
1-升级张量流:
pip install --user --upgrade tensorflow-gpu
(可能缺少一些软件包，只需点子安装即可)
(there might be some missing packages, just pip install them)
2-升级Tensorboard
2-Upgrade Tensorboard
pip install --user --upgrade tensorboard

(there might be some missing packages, just pip install them)
3-降级Keras
3-Downgrade Keras
pip install keras==2.3.1
(适用于我的最新版本)
(latest version working for me)
4-降级tensorflow-gpu
4-Downgrade tensorflow-gpu
pip install --user --upgrade tensorflow-gpu==1.14.0
(适用于我的最新版本)
(latest version working for me)
