title: Getting flags parsing error while running EfficientDet-D0
body: <p>After downloading the pre-trained model efficientdet-d0 (using Google automl repository), running the code below, gives me FATAL Flags parsing error. Any ideas how to fix this error? thank you.</p>
  <pre><code>!python model_inspect.py --runmode=saved_model_infer\
  --saved_model_dir={saved_model_dir} \
  --model_name={MODEL}  --input_image=testdata/img1.jpg\
  --output_image_dir={serve_image_out} \
  --min_score_thresh={min_score_thresh}  --max_boxes_to_draw={max_boxes_to_draw}
