Using Guix 929ddec, it fails as reported previously; using
tensorflow@1.9.0. Let try with tensorflow@2.13.1.
Well, although I have guix.bordeaux.inria.fr as substitutes, I had to
rebuild tensorflow. Ouch!
Then I get this:

Would you like to create a default python environment for the reticulate
package? (Yes/no/cancel) no

You can install TensorFlow using the install_tensorflow() function.
