It does not require the original model building code to run, which makes it useful for sharing or deploying (with TFLite, TensorFlow. 私はケラスをしゃべっていて、今のところ好きです。 かなり深いネットワークで作業しているときには、私が持っていた大きな問題が1つあります:モデル. In a workstation with multiple GPU cards, each GPU will have similar speed and contain enough memory to run an entire CIFAR-10 model. The way that we use TensorBoard with Keras is via a Keras callback. When I was researching for any working examples, I felt frustrated as there isn't any practical guide on how Keras and Tensorflow works in a typical RNN model. By default, TensorFlow pre-allocate the whole memory of the GPU card (which can causes CUDA_OUT_OF_MEMORY warning). I am working with a few experienced Googlers who have used Tensorflow/Tensorboard for years, and we still had no idea that this was the case (it made us think that we had made mistakes writing summaries etc). It takes a computational graph defined by users, and automatically adds swap-in and swap-out nodes for transferring tensors from GPUs to the host and vice versa. nvidia-smi to check for current memory usage. 1 Total amount of global memory: 11264 MBytes (11810963456 bytes) (28) Multiprocessors, (128) CUDA Cores/MP: 3584 CUDA Cores GPU Max Clock rate: 1645 MHz (1. Note that some operations are not available for GPU atm. Check Nvidia-smi. Note: If the model is too big to fit in GPU memory, this probably won't help!. So I think the biggest improvement for you would be to implement NCE loss function.
