tf.config.set_visible_devices

View source on GitHub

Set the list of visible devices.

tf.config.set_visible_devices(
    devices, device_type=None
)

Specifies which PhysicalDevice objects are visible to the runtime. TensorFlow will only allocate memory and place operations on visible physical devices, as otherwise no LogicalDevice will be created on them. By default all discovered devices are marked as visible.

The following example demonstrates disabling the first GPU on the machine.

>>> physical_devices = tf.config.list_physical_devices('GPU')
>>> try:
...   # Disable first GPU
...   tf.config.set_visible_devices(physical_devices[1:], 'GPU')
...   logical_devices = tf.config.list_logical_devices('GPU')
...   # Logical device was not created for first GPU
...   assert len(logical_devices) == len(physical_devices) - 1
... except:
...   # Invalid device or cannot modify virtual devices once initialized.
...   pass
