Got the following error message when tried to parse TensorFlow Lite official model ResNet_V2_101, the frozen pb file is resnet_v2_101_299_frozen.pb.

NotImplementedError: The following operators are not implemented: {'FIFOQueueV2', 'QueueDequeueManyV2'}

Potential fix: Skip the two ops by simply mapping to _undef, they are not related inference in this graphdef, any suggestion or comments? @srkreddy1238 @zhiics

It looks these two ops are also training related: https://www.tensorflow.org/api_guides/python/threading_and_queues
It is probably safe to map them to _undef.

@srkreddy1238 Could you please take a look and confirm? Thanks.
