I get this error

I am trying to convert this model: https://github.com/matpalm/bnn/blob/master/model.py

I converted the pb->tflite using

toco --graph_def_file=workspace/bnn_graph.predict.frozen.pb --input_format=TENSORFLOW_GRAPHDEF --output_format=TFLITE --output_file=workspace/bnn_graph.tflite --inference_type=FLOAT --input_type=FLOAT --input_arrays=input_imgs --output_arrays=train_test_model/output --input_shapes=1,768,1024,3

Which operator is not supported?
