During handling of the above exception, another exception occurred: Traceback (most recent call Single-host, multi-device synchronous training. run for an explanation. In this setup, you have one machine with several GPUs on it (typically 2 to 8). Unless specified, the value "auto" will be assumed, indicating that the reduction strategy should be chosen based on the current running environment. Server and there is another task that creates resources on workers and parameter servers, dispatches functions, and coordinates the training. TensorFlow Datasets から MNIST データセットを読み込みます。 これは、tf. The argument dataset_fn that users pass in is an input function that has a tf. keras and custom training loops. The next step's to ensure data is fed in expected format; for LSTM, that'd be a 3D tensor with dimensions (batch_size, timesteps, features) - or equivalently, (num_samples, timesteps, channels). The method employed to reduce per-replica values during training. distribute は、入力を自動的にデバイスに分散できる API を提供します。 The problem's rooted in using lists as inputs, as opposed to Numpy arrays; Keras/TF doesn't support former. In this example, you will train a simple convolutional neural network on the Fashion MNIST dataset containing 70,000 images of size Given a per-replica value returned by run, say a per-example loss, the batch will be divided across all the replicas. 16.
