www.tensorflow.org › guide › gpuNov 11, 2021 · By default, TensorFlow maps nearly all of the GPU memory of all GPUs (subject to CUDA_VISIBLE_DEVICES) visible to the process. This is done to more efficiently use the relatively precious GPU memory resources on the devices by reducing memory fragmentation. To limit TensorFlow to a specific set of GPUs, use the tf.config.set_visible_devices method.

https://www.tensorflow.org/guide/gpu11.11.2021 · TensorFlow code, and tf.keras models will transparently run on a single GPU with no code changes required.. Note: Use tf.config.list_physical_devices('GPU') to confirm that TensorFlow is using the GPU. The simplest way to run on multiple GPUs, on one or many machines, is using Distribution Strategies.. This guide is for users who have tried these …
