cellmap_flow.dashboard.routes.finetune.channel
==============================================

.. py:module:: cellmap_flow.dashboard.routes.finetune.channel

.. autoapi-nested-parse::

   The channel of a model of several that the viewer shows, in server mode:
   the browser's route (web/src/backend/routes/), answered by the dashboard,
   so the Finetune tab's pick (Use this model, the training form's Channel)
   shows the same in both.

   POST /api/finetune/channel {model_name, select_channel} records the channel
   (an index into the model's output channels, as select_channel takes it, or
   null to forget the pick) as the one to show of that model
   (Session.shown_channels), and moves the model's layer to it, and its
   running finetunes' that follow its pick, if the viewer has them: the paint
   and the training are for that channel (fly_organelles' mito, not all_mem,
   the first of its eight). Every layer built for the model after (a redraw,
   a start, viewer.layers prediction_layer), and for a finetune of it unless
   one was picked for that (Session.shown_channel), opens on it. A model with
   no channel axis, or under a chain that changes the number of its channels,
   shows no pick (viewer.layers display_channel refuses it). Forgetting the
   pick leaves the layer where it is, where the user may have moved it since.
   Answers ``{success, shown}``, ``shown`` whether a layer was moved.

   The 400 for a ``select_channel`` that is neither a channel's index (0
