Hello,
Even I was trying to convert the checkpoint to .tflite.

I converted successfully using "exporter_main_v2.py".

But when converting it to tflite I am facing issues.

Model I am using is "ssd_resnet50_v1_fpn_640x640_coco17_tpu-8"

I am using the export_tflite_ssd_graph.py to creating tflite file

In the script, I have disabled eager execution also.

Then I get the error

File "export_tflite_ssd_graph.py", line 148, in <module>
    tf.app.run(main)
  File "/usr/local/lib/python3.6/dist-packages/tensorflow/python/platform/app.py", line 40, in run
