Re: [theano-users] Why is this GpuFromHost call generated?

My guess is that you use the old GPU backend. Can you confirm you use the Theano flag device=gpu? And that also you have float64 in the graph. The old backend don't support them. I suggest that you install the just released 0.10 beta and that you use the new backend with device=cuda. Also,you can

Re: [theano-users] Replace a Shared Variable by a scalar

When you do y=... You don't replace y. Theano create a new node (a Python object), and assign it to a Python variable y. It is the same as if you named the second variable y2. I don't understand what you want to do, so I can't be more precise. Fred Le ven. 4 août 2017 20:22, a écrit : > Hello

Re: [theano-users] Split Op (OpFromGraph) to save intermediate results for grad

I don't understand what you mean by "forward the precomputed output" What I would recommand is to make 1 op for the forward. The intermediate value that can be reused for the gradient, make them output. Don't use them in the forward, but you can reuse them your grad override. Frédéric On Mon, Ju

You are mixing cuda 7.5 and 8 in your end variable. Never do this. Delete your Theano cache. It is not safe to reuse it. The new backend support cuda 8. Your warning is about cudnn version. This is not the same. If in a clean environment,you still have problems, give the error you have. Fred Le

Re: [theano-users] Re: How to delete theano model from GPU before initiating another model

Pure Theano Do not expect shapes. By default shapes can changes. You just need to be consistent in the computation you do on the shapes. If you set the batchsize shape to None, you are not using pure Theano. Do you use lasagne? Keras? Can you show the code where you set the shape to None? Fred

You don't need to re create a new model of you just change the batch size. What make you think this is needed? Some great framework on top of Theano will request that you set the batchsize to None to tell that it will change. Fred Le mar. 4 juil. 2017 17:21, Feras Almasri a écrit : > I'm re-ini
