tf.random.shuffle supported

[chan4cc]

I'm trying to convert a keras h5 model(create with tf1.12) to ONNX:

from tensorflow.keras.models import load_model

model = load_model(my_model_file)

onnx_model = keras2onnx.convert_keras(model, model.name)
onnx_model.save_model('model.onnx')

which report a error like:

WARN: No corresponding ONNX op matches the tf.op node cos_sim/RandomShuffle_6 of type RandomShuffle
      The generated ONNX model needs run with the custom op supports.
WARN: No corresponding ONNX op matches the tf.op node cos_sim/RandomShuffle_5 of type RandomShuffle
      The generated ONNX model needs run with the custom op supports.
WARN: No corresponding ONNX op matches the tf.op node cos_sim/RandomShuffle_4 of type RandomShuffle

There is an error(<class 'StopIteration'>) happened during optimizing on the converted model!

I tried pass param custom_op_conversions with {'RandomShuffle': tf.random.shuffle}, and it report the same error. it seems that keras2onnx not support op tf.random.shuffle yet?
