I’m reading the code for linkers and I have 2 questions:
1- Is there any reason why the file structure is different for numba and jax linkers?
2- Is there any way to print the generated code without compiling for debugging ? That was very useful with MCX.
Probably because Jax offers much more flexibility than Numba.
For instance take the case of Scan. Jax has an inbuilt scan like functionality, but in case of Numba we have to create the loops manually.
We can use code generation approach in Jax too, but i think we're yet to run into logic that cannot be implemented in Jax.
Op.performimplementations will ultimately be able to serve as the only necessary
lists serve as "pointers" to memory that Theano manages manually
brandonwillard: I tried to follow your blogpost on DLMs, but I didn't succeed in getting auto_updates to work with this minimal graph:
rng = aesara.shared(np.random.default_rng(), borrow=True) rng.tag.is_rng = True rng.default_update = rng def step(v_tm1, rng): v_t = at.random.normal(v_tm1, 1.0, name='v', rng=rng) return v_t v, updates = aesara.scan( fn=step, outputs_info=[np.array(0.0)], non_sequences=[rng], n_steps=5, strict=True, ) v_draws = aesara.function(, v, updates=updates)() assert len(np.unique(np.diff(v_draws))) > 1 # All values have the same offset
Any thing obvious I am missing?
for key, value in updates.items(): key.default_update = value
