Dear Sir,
Below code will produce compilation error: 'input_sizes' does not name a
type.
This is because input_sizes must be assigned inside a context of a function
in c++, right ?
std::vectorint input_sizes;
input_sizes.push_back(sizeof(float));
input_sizes.push_back(sizeof(double));

We have gr_modtool disable ABC to disable the ABC custom block.
But how to enable it back?

Huh, I thought I'd put

Something like :

So, yes and no on that. There's the information theoretic concept of
