The error load.stage-writer

environment: something the run needs is missing or different where it runs (a package, a file, a device, the network): the error names what to install, fetch or attach.

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/saved/_folder.py:

  • what happened: the stage was written by stage writer {…}, and this MIME writes versions {…}

  • what to do: install the MIME that saved it, 'pip install mime-engine=={…}', or build the experiment from its script and save it again: 'built.save(folder)'

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