Zero nodes when converting to memmapped format. Deepspeech

Hello,
I have successfully downloaded the convert_graphdef_memmapped_format. However, I am getting 0 nodes:

./convert_graphdef_memmapped_format --in_graph=/home/neha/Documents/DeepSpeech/test/export/output_graph.pb --out_graph=/home/neha/Documents/DeepSpeech/output_graph.pbmn

2020-11-07 16:43:40.497728: I tensorflow/contrib/util/convert_graphdef_memmapped_format_lib.cc:171] Converted 0 nodes

Can you please advise. I saw that model has to be frozen in the documentation, please advise on how to proceed.

Hard to tell as you don’t give us any info on the model data:
