Hi all. There's some really unintuitive/inconsistent behaviour with theano's scan and I'm wondering how I should work around it. Take the following test, which I would expect to pass: import theano import theano.tensor as tt def test_scan_tuple_output(): x = tt.matrix() def

[theano-users] Re: How to: data parallelism in new GPU backend

2017-01-16 Thread Adam Stooke
Thinking of a different design: 1. Master python process builds and compiles all theano functions like normal (for GPU), and pickles them. 2. Worker processes initialize on other GPUs and unpickle all the functions. 3. User calls wrapped theano functions in master process, which signals to
