  • scalene

    Scalene: a high-performance, high-precision CPU, GPU, and memory profiler for Python

    I ran the code and copied and pasted the results. Code is here:

  • Keras

    Deep Learning for humans

    The report output for scalene does look much nicer, but the slowness for me dropped me from continuing to use it. Maybe there's some bad interaction with tensorflow/pytest. I can try to make an example, but I'd guess if you try running it on tensorflows actual unit tests (something like this) you'd get similar behavior.
