Keras Not Found

[etrauger]

I am sure I am making a relatively simple mistake having to do with how my environment is set up. In running relatively simple test code, I get the following error:

Using TensorFlow backend.
Error: Python module keras was not found.

I believe my issue may be similar to the issue brought up on this page but I am not sure how the problem was actually solved.

For some reason Keras isn't loadable (this could be for many different reasons). To get a better error message try this:

library(keras)
reticulate::py_run_string("import keras")
