What should a PhD in physics put in a CV?
This is why it's a good idea to think about these things during, or preferably before, your PhD. You're picking up skills, but how useful those skills are and how you're going to use them is a big question. Fortunately, you're not out of options, and you've probably learned more than you think. Some thoughts:


You should absolutely list Keras. With the amount of hype machine learning has been getting having experience with neural networks is a big deal. I'd go much more than that: list everything you know about data analysis. It doesn't matter if it's something as simple as linear regression. List it all, give details.
You should absolutely list Python as well. In fact, list all the programming languages you know. You don't have to be an expert in all of them because you can learn the others quickly. Are you able to read C/C++ code? Java? R? You can also list Mathematica.
You should absolutely list all the languages you can speak. These skills aren't easy to pick up. If you can speak Japanese for example, that might make you the only viable candidate for a company that's looking to send a consultant to a Japanese client.
What else did you learn in your research? Did you learn any algorithms that might have wider applications? For example, did you learn how to parallelize code? Did you learn how to use a Linux terminal? Git and Github?
Did you engage in science communication and / or teaching? If so definitely list this as well, since it indicates you can mentor others.


You should also visit your university's career center. They'll have experts who can help you.

EDIT: One more thing, take a look at the advertisements you're responding to before sending in a CV. Do you know any of the things they request? For example looking at one such advertisement, there's this:


  
  Ability to query a SQL and/or NoSQL database efficiently
  


If you know how to do this, you should absolutely list it on your CV as well.
