|
|
* fails to launch, execute_1_3 must immediately invoke the callback with

* execute_1_3 function. This callback must be provided with the ErrorStatus of

* the execution.

|
|
* any data object referenced by 'request' (described by the

* {@link @1.0::DataLocation} of a {@link @1.0::RequestArgument}) until the
|
|

|
|
* must not change the content of any of the data objects corresponding to

* If the prepared model was prepared from a model wherein all tensor
|
|
* operands have fully specified dimensions, and the inputs to the function
|

|
|
* - the execution should launch successfully (ErrorStatus::NONE): There
|
|
* must be no failure unless the device itself is in a bad state.

|
* - if at execution time every operation's input operands have legal
|

* values, the execution should complete successfully (ErrorStatus::NONE):

|
|
* to an abort must be sent the same way as other errors, described above.
