Model Optimizer ERROR for .pb to .xml/.bin

[wang__libing]

I tried to convert  .pb model to .xml/.bin in OpenVINO R5 just following the official instructions.It is successful to create a .bin model,but failed to create a .xml model.

 It shows the error:

[ ERROR ]  List of operations that cannot be converted to IE IR:
[ ERROR ]      Exp (1)
[ ERROR ]          activation_1/Exp
[ ERROR ]      Sum (1)
[ ERROR ]          activation_1/Sum
[ ERROR ]  Part of the nodes was not translated to IE. Stopped. 
 For more information please refer to Model Optimizer FAQ (<INSTALL_DIR>/deployment_tools/documentation/docs/MO_FAQ.html), question #24.

Does anyone know how to fix it?

Those layers are unsupported layers. To convert, you need to create a custom layer yourself. https://software.intel.com/en-us/articles/OpenVINO-ModelOptimizer#inpage-nav-4
