AssertionError: Export directory already exists. Please specify a different export directory: inference_graph\saved_model

Answer 1

It's saying the directory already exists. Either change your command in the terminal to point to a new directory or remove everything in this directory that you are currently setting as the output directory.

Answer 2

python3 export_inference_graph.py \
--input_type image_tensor \
--pipeline_config_path YOUR_PIPELINE.CONFIG_FILE_PATH \
--trained_checkpoint_prefix YOUR_MODEL_CHECKPOINT_PATH  \
--output_directory exported_graphs/saved_model2

Your try changing output directory.For example exported_graphs/ saved_model2 as above.
