I'm using anaconda on a Windows 7 64 bits.

This is what I did:

conda update conda
conda create --name my_env python=3.5
conda activate my_env
conda install -c conda-forge tensorflow=1.8

When I try to install keras 2.0.5:

conda install keras=2.0.5

I get this message:

Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible so lve. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible so lve.

  • keras=2.0.5

Current channels:

To search for alternate channels that may provide the conda package you're looking for, navigate to

https://anaconda.org

and use the search bar at the top of the page.

I have also tried:

conda install -c conda-forge keras=2.0.5

With the same above message.

I have checked if keras is already installed:

python -c "import keras; print(keras.__version__)"

With the message:

ImportError: No module named 'keras'

I search keras package:

conda search keras

With the output:

It seems we never packaged 2.0.5. The easiest would probably be to install it with pip. If you really need a conda package, you could in principle build one in the conda-forge/keras-feedstock. – cel

You may consider using pip to install and its supported in Conda environment.
Use command:

pip install Keras==2.0.5

This would not throw any error.
