The error controller.impure

user: the script can change it: the error says what happened in the experiment’s names, and what to write instead.

Where MIME gives it, with what its message says happened and what its action says to do ({…} is filled in from the experiment):

• in mime/build/_in_graph.py:

  • what happened: the controller {…} cannot run inside the compiled step (mode {…}): {…}

  • what to do: run it as a callback, mode={…}, where each call of its step runs; or write its step as a pure function of its state and reads, with what changes between ticks in its state

Reading an error and reaching its full traceback: reading an error. Every code: the index.
