Unable to create model file 'detect.tflite' to use with TensorFlow Lite!

I executing the following command:

bazel run --config=opt tensorflow/lite/toco:toco -- --input_file=../../models/research/object_detection/TFLite_model/tflite_graph.pb --output_file=../../models/research/object_detection/TFLite_model/detect.tflite --input_shapes=1,300,300,3 --input_arrays=normalized_input_image_tensor --output_arrays=TFLite_Detection_PostProcess,TFLite_Detection_PostProcess:1,TFLite_Detection_PostProcess:2,TFLite_Detection_PostProcess:3 --inference_type=QUANTIZED_UINT8 --mean_values=128 --std_values=128 --change_concat_input_ranges=false --allow_custom_ops

Command response:

Although file is exists. I have checked it properly. Also I put the file in the same directory despite not working.
