simple gradient: Error During Test at REPL[59]:1
51+
Got exception outside of a @test
52+
Constant memory is stored (or returned) to a differentiable variable.
53+
As a result, Enzyme cannot provably ensure correctness and throws this error.
54+
This might be due to the use of a constant variable as temporary storage for active memory (https://enzyme.mit.edu/julia/stable/faq/#Runtime-Activity).
55+
If Enzyme should be able to prove this use non-differentable, open an issue!
56+
To work around this issue, either:
57+
a) rewrite this variable to not be conditionally active (fastest, but requires a code change), or
58+
b) set the Enzyme mode to turn on runtime activity (e.g. autodiff(set_runtime_activity(Reverse), ...) ). This will maintain correctness, but may slightly reduce performance.
