See tf.config.get_logical_device_configuration and tf.config.set_logical_device_configuration for usage examples.


  • memory_limit: (optional) Maximum memory (in MB) to allocate on the virtual device. Currently only supported for GPUs.
  • experimental_priority: (optional) Priority to assign to a virtual device. Lower values have higher priorities and 0 is the default. Within a physical GPU, the GPU scheduler will prioritize ops on virtual devices with higher priority. Currently only supported for Nvidia GPUs.
