ValueError: Unsupported Ops in the model before optimization LogSoftmax

Hi, I'm trying to convert a .pb file using

tensorflowjs_converter --input_format=tf_frozen_model --output_node_names='LogSoftmax,concat_40,concat_41' --saved_model_tags=serve test.pb testout/test

and get an error

Using TensorFlow backend.

LogSoftmax

tensorflow.js version

Using TensorFlow backend.

tensorflowjs 0.5.7

Dependency versions:
  keras 2.1.6
  tensorflow 1.9.0

Is that operation not satisfied? Any way I could add it?
Thanks a lot!
