Looks like Python 3.7 is not supported yet:

Somewhat off topic: I'm rediscovering the dance required to set up a new Windows 10 laptop with Python, CUDA, and TensorFlow. If I understand correctly, pyenv does not work on Windows. Is there something similar?
Also, if I installed TensorFlow in WSL, it wouldn't be able to use the GPU, would it?
