Failure in Loading a Single Operator Due to an OPP Version Issue

Symptom

An error is reported during the loading of a single operator. Information similar to the following is displayed in the log:

E19999: Inner Error
E19999 The opp version of the model does not match the current opp run package, Model is [6.4.T11.0.B300], opp run package is [7.0.T3.0.B107], try to convert the om again!

Possible Cause

In the dynamic-shape or Ascend virtual instance operator scenario, the OPP installation version in the environment for loading single-operator model data (the package name is Ascend-cann-toolkit _{version} _linux-{arch}.run) is inconsistent with the OPP installation version in the environment for building the .om model file. As a result, an error is reported during operator loading.

Solution

In the dynamic-shape or Ascend virtual instance operator scenario, the OPP installation version in the environment for loading the single-operator model data must be the same as the OPP installation version in the environment for compiling the .om model file. If this error is reported, check the installation version and replace the OPP package version in the operator loading environment or that in the environment for compiling the operator .om file. If you choose to replace the latter, you need to convert the model again.
