Windows 64: keras

Posted by flopit about 2 years ago


next challenge is to get keras for windows-64 installed, can you please also provide help (as with the opensim package; maybe there is a URL for keras for Windows available)? Thanks!

Regards Florian


(opensim-rl) C:\WINDOWS\system32>conda install keras Fetching package metadata ………..

PackageNotFoundError: Package not found: ‘’ Package missing in current win-64 channels: - keras

You can search for packages on anaconda.org with

anaconda search -t conda keras

Did you try : pip install keras

inside the conda environment ?

No, I am afraid it does not help: …

or this : conda install -c jaikumarm keras=1.2.0

Hi, unfortunately installing keras on windows is a big challenge in general. Some people succeeded - you can try this: http://ankivil.com/installing-keras-theano-and-dependencies-on-windows-10/

or as Mohanty suggested conda install -c jaikumarm keras=1.2.0

Our environment is fully independent from keras, so you can use any other RL framework available on windows, ex. https://pypi.python.org/pypi/Reinforcement-Learning-Toolkit/1.0 https://github.com/rlpy/rlpy

Please let us know if you succeed moving forward.

Best, Łukasz

Hi, I am unable to install theano on my windows 7 machine using anaconda3-4.2.0. I am using python3.5.

I searched lot of Q and A on stackoverflow but couldn’t resolve the issue. some posts mentioned to use anaconda’s older version which uses python3.4 or earlier pthon3.x But i couldn’t find such anaconda version on the continnum website. Could anybody suggest me the correct way to install theano.

Many Thanks

EDIT: I will check the link mentioned in the discussion thread and come back how it goes. http://ankivil.com/installing-keras-theano-and-dependencies-on-windows-10/

Hi I am afraid I still can not get keras running with the command and links you provided. The new code for submitting (havent seen the old one) for submitting uses “import keras”. Do I need keras for submitting?

@flopit : No you do not need keras for this challenge. As @Lukasz mentions, you are free to choose any framework that works for you. To help you quickly get started, here is a gist detailing how you can put up a submission with random actions (and the inline comments also have pointers on what changes you would need to make when you are changing between a submission script and a training script.

Hi, what version of Windows do you have? If it’s Win 10, pip install worked ok for me. But I didn’t try it installing Keras in the conda environment and still is using Ubuntu for opensim-rl.
