theano.fuction in cuda mode takes hours to compiles

[jiangnanhugo]

I implement a seq2seeq model and find that in cuda mode, it cannot pass the theano.function step, and it works in cpu mode. can anyone offer me any idea?
theano version 1.0.3

What do you mean by canot pass the theano.function step? It is not usual that it compile for hours on GPU while it is fast to compile on the CPU.

But we do not develop Theano anymore, so I would be surprisez if someone work on this. But to have a chance of having someone to work on this, you should give code that allow people to reproduce the problem. This is needed for this type of problems.
