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，但我无法导入 Keras，因为我收到以下错误消息:
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
Keras requires TensorFlow 2.2 or higher. Install TensorFlow via
pip install tensorflow
问题是我别无选择，只能安装 Tensorflow 1.15，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(没有 avs，只有 SSE)
- Windows 7 64 位操作系统
- 英伟达 GPU
- CUDA 10.1
我必须为该 Python 版本、我的 CPU 和名为tensorflow-1.15.0-cp37-cp37m-win_amd64"的 CUDA 版本下载并安装一个轮子.
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 似乎可以工作(它检测我的 GPU 并打印hello world"消息)，但问题在于 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，新版本兼容什么?
How can I specify an older, compatible version, and what is the newer version compatible?
推荐答案
我在上次 keras 版本中遇到了同样的问题，我记得是这样的():
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
(可能缺少一些包，直接pip安装)
(there might be some missing packages, just pip install them)
2-升级 Tensorboard
2-Upgrade Tensorboard
pip install --user --upgrade tensorboard
(可能缺少一些包，直接pip安装)
(there might be some missing packages, just pip install them)
3-降级 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)
如果有效请告诉我！
