Keras Multi Gpu Example

Keras Multi Gpu Example. Please keep in mind that cyclegan is used as an example due to its (relatively) complex loss calculations and. A keras `model` instance which can be used just like the initial `model` argument, but which distributes its workload on multiple gpus.

Scaling Keras Model Training to Multiple GPUs NVIDIA Developer News from news.developer.nvidia.com

When using multi_gpu_model (i.e., tf.keras.utils.multi_gpu_model) in tensorflow 2.0 to distribute a job across multiple gpus (4), only one gpu appears to be used. Kerastuner also supports data parallelism via tf.distribute.data parallelism and distributed tuning can be combined. Test on 2 1080ti gpus with:

Using tf.distribute.mirroredstrategy( ) since tf.keras.utils.multi_gpu_model( ) is deprecated and removed since april 2020. Tensorflow code, and tf.keras models will transparently run on a single gpu with no code changes required.

# Since The Batch Size Is 256, Each Gpu Will Process 32 Samples.

I'm using 1 gtx1080 and 3 gtx1070. Def multi_gpu(model, gpus=none, cpu_merge=true, cpu_relocation=false): And then calling multi_gpu_model which nests the model again when it splits the model once for each gpu using lambda and then concatenates the outputs back together in order to distribute the model over multiple gpus.

Concatenate The Results (On Cpu) Into One Big Batch.
