Flux.@functor errors

[BCRARL]

This cell didn't work in a a brand new notebook and I can't see why it shouldn't

begin
	using Flux
	struct Reshape
	   shape
        end; 
	Reshape(args...) = Reshape(args); 
	(r::Reshape)(x) = reshape(x, r.shape);
	Flux.@functor Reshape ()
end

The response is

LoadError: UndefVarError: Flux not defined
in expression starting at .julia/pluto_notebooks/Cute program.jl#==#3623c510-f95d-11eb-149e-c99cf971ce14:8

This is the same problem as #1340 (comment). You can solve it by moving using Flux to its own cell.

Except that the split followed by

using BSON

and then loading a Flux model with

BSON.@load "path" Model

leads to

UndefVarError: Flux not defined

[BCRARL]

That's what I call a catch 22

[Pangoraw]

You should use BSON.load("path", @__MODULE__) because the using Flux is not in Main but in workspaceXXX (due to Pluto internals). You can help Pluto determine the execution order by adding a dummy reference to Reshape in the loading cell:

begin
    Reshape # to make sure Reshape is defined before this cell is run
    model = BSON.load("path", @__MODULE__)[:model]
end

[BCRARL]

At this point I am manually building the execution tree with hacks. I guess Pluto is not the right solution to my development needs.
