mindspore.set_deterministic

mindspore.set_deterministic(deterministic)

Enables or disables deterministic computing.

This configuration is a global configuration, and once enabled, subsequent calculation operations will follow the configuration setting. When deterministic computing is enabled, the same output is generated if an operator is executed for multiple times with the same hardware and input. This often slows down operator execution.

The framework not enabled deterministic computation by default.

Note

• In distributed scenario, we suggest user to set deterministic computing before calling mindspore.communication.init() to enable deterministic operation for communication operators in the global communication group.

• The fixed method for deterministic calculation must be in the same main process as the network, operator, etc. Only one deterministic state can be set in the same thread, and it is not recommended to set deterministic state multiple times in one thread.

Parameters

deterministic (bool) – Whether to enable deterministic computing.

Examples

>>> import mindspore as ms
>>> ms.set_deterministic(True)
