I would like to convert pb file which is in ssd_mobilenet_v1_quantized_300x300_coco14_sync to uff file. So, I tried use convert_to_uff.py. But, I could not do this work.

$python3 /usr/lib/python3.6/dist-packages/uff/bin/convert_to_uff.py tflite_graph.pb -o ssd_mobilenet_v1.uff -O NMS -p config.py

My config.py is config.py.txt (2.0 KB)

The error message are following:

How can I convert pb file to uff file? Thank you for your support.

Hi,

The error indicates the layer for removal mentioned in the config.py file doesn’t exist.
Could you delete following two lines and try it again?

all_assert_nodes = dynamic_graph.find_nodes_by_op("Assert")
dynamic_graph.remove(all_assert_nodes, remove_exclusive_dependencies=True)

Thanks.

Thank you for your support! I remove 2 lines from config.py. But, the error was same:

Hi,

Sorry that there is some mistake. The error is caused by the line below:

dynamic_graph.find_nodes_by_op("NMS_TRT")[0].input.remove("Input")

Please remove the line instead.

Thanks.
