Error "Keras requires TensorFlow 2.2 or higher"

Question

I just installed Visual Studio 2019 and Tensorflow, but I cannot import Keras because I get the following error message:

Keras requires TensorFlow 2.2 or higher. Install TensorFlow via pip install tensorflow

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 (no avs, only SSE)
• OS Windows 7 64
• Nvidia GPU
• CUDA 10.1

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 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.

How can I specify an older, compatible version, and what is the newer version compatible?

Answer 1

I had the same issue caused by last keras release,what i remember did():

1-Upgrade tensorflow:

  pip install --user --upgrade tensorflow-gpu 

(there might be some missing packages, just pip install them)

2-Upgrade Tensorboard

pip install --user --upgrade tensorboard 

(there might be some missing packages, just pip install them)

3-Downgrade Keras

pip install keras==2.3.1 

(latest version working for me)

4-Downgrade tensorflow-gpu

pip install --user --upgrade tensorflow-gpu==1.14.0 

(latest version working for me)

Let me know if worked!

Answer 2

Following the advice given here, downgrading Keras did the trick for me without having to touch any other packages. Just do:

pip install keras==2.3.0 

I hope this only remains a temporary issue and will be fixed in future versions of TensorFlow and Keras.

Other possible solutions, are discussed here.
